**Section 1**  **- Aircraft** **Electronics**

**MC** - The **M** ain **C** ontroller is the brain of the Phantom. The MC is the primary flight control computer that contain the programming firmware. It connects the IMU, GPS, Compass, ESC and R/C Receiver to achieve manage stable flight and aircraft control by issuing high speed control commands to each motor. **IMU** - An inertial measurement unit (IMU) is an electronic device that measures and reports a craft's velocity, orientation, and gravitation al forces, using a combination of accelerometers and gyroscopes, sometimes also magnetometers. An IMU is used to maneuver aircraft Phantom, among many others, and spacecraft, including satellites and landers. Recent developments allow for the production of IM U - enabled GPS devices. The IMU allows the GPS receiver to work when GPS - signals are unavailable. Read More **ESC** - Each of the motors on the Phantom has an **Electronic Speed Control** or ESC which is an electronic circuit with the purpose to vary the motor's speed, its direction and possibly also to act as a dynamic brake. ESCs are critical to the brushless motors, essentially providing an electronically generated three - phase electric powe r low voltage source of energy for the motor. **GPS -**  **What is the IMU and how does it work** The IMU Inertial Measurement Unit is a small boxcomponent on the motherboard containing three accelerometers and three gyroscopes. The accelerometers are placed so that their measuring axes are orthogonal to each other. They measure inertial acceleration, also known as G -fo rces. These are really incredible devi ces that make miniaturization possible. You probably have one in your smart phone. The IMU in the Phantom 3 works by detecting the current rate of acceleration using micro accelerometers, and detects changes in rotational attributes like pitch, roll and yaw using micro gyroscopes. The compass (magnetometer) assists to counter orientation drift. The angular accelerometer measure how the Phantom is rotating in space. There is one sensor for each of the three axes: pitch (nose up and down), yaw (nose left a nd right) and roll (clockwise or counter- clockwise). The linear accelerometers measure non - gravitational accelerations of the aircraft. Since it can move in three axes (up & down, left & right, forward & back), there is a linear accelerometer for each axi s. The Main Controller (MC) of the Phantom continually takes the data feed from the IMU and calculates the aircraft’s current position. First, it integrates over time the sensed acceleration, together with an estimate of gravity, to calculate the current velocity. Then it integrates the velocity to calculate the current position. The Main Controller of the Phantom also integrates inputs from the GPS system, barometric pressure sensor for altitude correction, and the magnetic compass.IM U’s aren’t perfect and a major disadvantage of using IMUs for navigation is that they typically

suffer from accumulated errors. Because the guidance system is continually adding detected changes to its previously- calculated positions, any errors in measurement, however sma ll, are accumulated from point to point. This leads to 'drift', or an ever- increasing difference between where the system thinks it is located, and the actual location. Because the devices are only able to collect data in a finite time interval, IMUs are always working with averages. So if an accelerometer is able to retrieve the acceleration once per second, the device will have to work as if that had been the acceleration throughout that whole second, although the acceleration could have varied drastical ly in that time period. Of course modern devices are able to collect data much faster than once per second, but over time that error increases exponentially. Because the sensors in an IMU are so delicate, they are also very sensitive to temperature. Duri ng the calibration process, the phantom has an internal heater that will heat it to the max temp. So if you start the imu cal at 25 deg c and the max temp is 50 deg c then the imu cal has accurate data from 25 - 50 deg c. If you do an imu cal when it is already hot, 45 deg c let's say, then it'll warm to 50 deg c , and then you'll only have accurate data from 45 - 50 deg c. So what does this mean when you fly? The phantom starts warming up (literally using its internal heater. This is a physica l warm up) to the range it was calibrated in. Calibrate it across a wider range (25 - 50) and when you fly in 20 deg c weather, it only has to warm up 5 degrees. That should be 20 - 30 seconds or so. But if you calibrated it in the 45 - 50 degree range, then it needs to warm up 25 degrees. That'll take longer. Maybe up to 2 - 3 minutes? Not sure. 

## What are Flight Modes **Available Flight Modes** Three flight modes are available. The details of each flight mode are found below: 

### P - mode (Positioning) : P - mode works best when GPS signal is strong. There are three different states of P - mode, wh ich will be automatically selected by the Phantom 3 Professional depending on signal strength of GPS and Vision Positioning sensors :  **P -**  **GPS:** GPS and Vision Positioning both are availa ble. The aircraft is using GPS for positioning.  **P -**  **OPTI:** Vision Positioning is available but the GPS signal strength is not sufficient. The aircraft is using only the Vision Positioning System for positioning.  **P -** **AT TI:**  Neither GPS nor Vision Positioning is available. The aircraft is using only its barometer for positioning, so only altitude can be stabilized. 

### A - mode (Attitude): GPS and Vision Positioning System are not used for stabilization. The aircraft only uses its barometer. The aircraft can still automatically return to the home point if the control signal is lost and the Home Point was recorded successfully.

### F - mode (Function):

Intelligent Orientation Control (IOC) is activated in this mode. Use the Flight Cont roller mode switch to change the flight mode of the aircraft, refer to the “Flight Mode Switch” 

### Flight Mode Switch Toggle the switch to select the desired flight mode. You may choose between; P - mode, F - mode and A mode. **Operating Note:** By default, the Flight Mode Switch is locked to P - mode. To unlock other flight modes, launch the DJI Pilot app, enter the “Camera” page, and tap “Mode”, then activate “Multiple Flight Mode”. 

### Flight Data Recorder 

## What is the “Internal” Flight Data Record er and what does it do? Flight data is automatically recorded to the internal storage of the aircraft. This includes flight telemetry, aircraft status information, and other parameters. To access this data, connect the aircraft to the PC through the Micro - USB port and launch the DJI Pilot app. Notes: This is not the camera media micro SD Card, it is a different micro SD card internal to the P3 and not removable and only accessible using the micro - USB port on the front of the P3. This hidden micro - SD card records the flight data logs. creating large .DAT files. In order to access the >DAT files, or your can go to mode, advanced enter flight data mode. Then connectthe usb cable to your computer. You will see a folder on your desktop. You can manually clean

out the drive there. Power cycle the P3 and it will clear the card 

### DJI Phantom 3 Firmware Update Procedures

**Disclaimer** - Please verify these instructions with the official DJI Update instructions that get downloaded along with the firmware update package from the DJI website. If in doubt - Ask DJI. 

### Overview The DJI Phantom 3 is an incredibly sophisticated UAV and if properly maintained and operated will provide photo opportunities never before possible at a reasonable price. Taking the time to know and understand this flying machine will prove satisfying and interesting for many flights to come. Firmware is the fixed programs and/or data structures that resides on the internal board processing chips of the Phantom and controls virtually all of the operating functions of the copter. The Phantom 3 will not operate without correctly installed firmware as it is essentially the brains of the Phantom. Proper firmware upgrading is one of the first and also one of the most important tasks you must accomplish correctly as the owner of a new Phantom. You must get this right and although the procedure may seem overwhelming at first, take your time and follow the process described below to upgrade the aircraft, remote controller and battery firmware. Described here, is Part 1, which updates th e Phantom 3 Aircraft Firmware and Part 2 which updates the remote controller firmware. In step 2, you will see three different options to get the firmware file (.bin) that is still residing on the microSD card after Part 1, over to the Remote Controller. There is no preferred option for Step 2, just whatever you feel most comfortable with and whether or not you have the USB adapter or thumbdrive. 

### Before you start Read through these instructions completely before you begin and it will help you a great deal in accomplishing the update procedure effectively. If there is a step you don’t understand, do not start the process until you do. Take your time, turn off the distractions and pay attention to what you are doing, this is important. If you have any quest ions, ask someone on one of the many forums; this is all part of learning your job as a Phantom Pilot. **Ad ditional Notes and cautions:**   **Do not perform firmware update while the aircraft is still fly ing in the air.**   Be sure to update the remote controller’s fi rmware to the latest version after you upgrade the aircraft’s firmware.  The remote controller may become unlinked from the aircraft after updating. Re - link the remote controller and aircraft. Confirm the update results according to the gimbal sounds. I t is normal for the aircraft

to sound or the LED to blink during the update process.  Ensure there is only one firmware package file stored on your SD card.  Only storage devices that are formatted for FAT32 and exFAT file systems are supported for aircraf

t and remote controller firmware updates. Delete any automatically generated txt files (xxx_GS.TXT) in the SD card when updating multiple remote controllers.  Perform a compass calibration as part of the process 

### Battery Charge Before you start, make sure the Phantom 3 flight battery and the remote controller are at least 50% charged. You can check the battery charge level by pushing once on the flight battery power button. Likewise with the remote controller, press once on the power button. You should get at least two of the four indicator lights to light up. The firmware update procedure is accomplished in two parts that must be done in order. The fi rst step is to update the Phantom 3 aircraft firmware and the second step is to update the remote controlle r firmware. (note: battery firmware is updated automatically once the firmware is up to date - and the .bin file (the .bin file is the actual firmware update) remains on the camera micro - SD card that is installed in the Phantom camera component. 

### Tools To accomplish the upgrade, you will need a micro - SD card adapter. SInce the micro - SD card that comes with the Phantom is fairly small capacity, you will get the card reader when you purchase a larger capacity card. You can use this same reader for the upda te process. If you choose Part 2 - option 2, you will need a MicroSD - USB Adapter card. If you choose Part 2 - option 3, you will need an USB thumbdrive with at least 100MB capacity. 

### Part 1 **- Updating the Aircraft Firmware**  1. Check the battery and SD Card Capa city making sure that the Intelligent Flight Battery has at least 50% power and there is at least 100MB of free space on the SD card. You can check battery levels on both the flight battery and the remote controller by pushing once on the power button for one second. You should have at least two bars on the indicators, if not, take the time to charge the devices. 2. Verify that power is off for both the aircraft and the remote controller. 3. Download and preparation of the firmware update package - download the firmware update package from the official DJI website ( http://www.dji.com/product/phantom - 3 ). **Caution:**  Wh en downloading the firmware from the DJI website, double check to make sure you download the firmware for the correct model - there is separate packages for the Professional and Advanced versions.  Remove the Gimbal Guard as it moves when the copter is powered on.

**Note:** for ease of download, the firmware package consists of two files that are zipped into a.zip file. One file is an instructional pdf file for reference only and the other file is a .bin file that

is the actual firmware update. Unzip the downloaded file anywhere onto your PC/mac and remember wh ere you put it, then copy the .bin file that was just unzipped, to the root directory of the SD card. (the root directory is the first directory you see when you view the card) **Note: if the .bin file is not in the root directory, the update will not work** 1. Remove the micro - SD card from the Phantom camera and insert the card into the adapter card and then into your PC. Proceed to copy the bin file as described above onto the card. Delete any old .bin files or .txt files that may be on the card from previous updates. Once the .bin file is copied to the SD card, remove the SD card from your PC, ensure the aircraft is powered off then insert the micro - SD card back into the Phantom camera card slot. - You are now ready for the firmware update to the aircraft. 2. Aircraft Firmware Update - Once the card is installed, power on the aircraft, **do not** power on the remote controller. The upgrade will begin automatically after the craft is powered on and after a brief pause. The camera will sound pulses of "D - D - D - D" beepi ng sounds to indicate the upgrade is in progress, this will continue for the duration of the upgrade process which could take up to 25 minutes, but, more likely will only take a few minutes depending on the size of the upgrade. Once the upgrade is complete, the sound will switch to a “D --- DD” beeping sound to indicate the update is completed with success. 3. The process generates a .txt file back onto the micro - SD card once the update is complete, in the same location as the bin file. 4. Power down the copter, remove the micro - SD card and put it back into your pc. Locate this txt file and open it, it will tell you if the upgrade was successfull or not. If not- try updating the firmware again if the text “result: failed” is found or the gimbal sounds a long bee p sound. 5. Delete the txt file once you have verified a successful upgrade to the phantom. Congratulations, now on to the Remote Controller. 

### Part 2 (option 1) **- Updating the Remote Controller Firmware**  This option uses the micro - USB cable that came in the box to update the remote controller from the firmware file (.bin) that was copied onto the camera MicroSD in Part 1. 1. Check Battery and SD Card Capacity - Minimum 50% on both the flight battery and the remote controller. 2. Wi th power still off on the Phantom, insert the Micro - SD card back into the Phantom camera slot. 3. Connect the micro - USB cable (the one that came in the Phantom box), the micro USB end to the Phantom camera, the standard USB end to the con troller. (see photo)4. Power on the Phantom, it should be a normal start- up.

5. Power on the remote controller and wait a few seconds and the upgrade will begin. Do not power off the remote controller during the update. 6. It will take several minutes to complete the firmware update. The controller will sound a beeping sound and the Status LED on the remote controller will show solid blue to indicate the update is in progress. This will cycle several times before completion. Once complete, the Status LED on remote controller will turn solid green and the beeping sound will stop. The Status LED on the remote controller will turn solid red if upgrade fails, in this case, try the upgrade again. 1. Power off the Controller and the Phantom 2. Remove the micro - SD card from th e Phantom camera, and put it back into the PC/mac. The remote controller update process also generates a .txt file upon completion that you can verify successful completion by reading the txt file on your PC. 3. Once you have verified a successful update of the remote controller, delete the txt files that were generated after the update and put the micro - SD card back into the Phantom camera. 

### Part 2 **- (**  **option 2 ) Micro SD**  **- USB Adapter**  This step is another way the get the firmware (.bin) file to the remote controller. 1. After completion of part 1, remove the microSD card from the Phantom camera slot and place it into your microSD - USB adapter. 2. Insert the USB adapter into the Remote Controller USB port and proceed with step 5 of Part 2 - Option 1.Transcend Adapter



### Part 2 **- (**  **option 3 ) USB Flash Drive**  This step is another way the get the firmware (.bin) file to the remote controller. 1. Insert a USB thu mbdrive into your PC/Mac and copy the update bin file to the root directory of the USB thumbdrive 2. Insert the USB thumbdrive into the USB port on the remote controller and proceed with step 5 of Part 2 - Option 1.



### Updating Intelligent Flight Battery **Firmware** The Intelligent Flight Battery is updated during the aircraft firmware update process. It is recommended to keep the latest upgrade .bin files on your SD card, this will update any addition batteries when they are installed. The upgrade will start automatically after power cycling the aircraft. **Ad ditional Firmware Update Verification**  - You can also verify that the installation of the fi rmware update is completed correctly by connecting your tablet back into the USB port on the remote controller, turning on the remote controller and turning on the Phantom 3 aircraft. Openthe Pilot App and when you select “Camera” from the home page, the first info screen “Aircraft

State” will show the firmware status. Alternatively, select the aircraft parameter icon in the upper right corner, then select aircraft general/about in the pop - up menu to show the current firmware version. **Last Resort:** If you have tried all the above methods and still cannot get the update to work, try turning on both the controller and phantom with the bin file on the card. This has worked as a last resort for some folks. 

### Video Tutorials: note: these Youtube tutorial describe different ways to upgrade, and are all effective in completing the job. https://youtu.be/aSPRLjnTwc4 https://youtu.be/BNs5UdvKbm4 https://youtu.be/DNfL4nN1fMc https://youtu.be/- Ni7Z_NPfck https://youtu.be/oOfCK47eiyY https: //youtu.be/bWl oW B8 Mj 6A 

### DJI Phantom 3 Intelligent Orientation Control (IOC) 

## What Is IOC IOC allows users to lock the control orientation of the aircraft in different modes. There are three working modes for IOC that can be selected in the DJI Pilot app. IOC only works when the aircraft is in F - mode, therefore the user must toggle the flight mode switch to activate IOC. Refer to the table below 

## IOC Modes **Course Lock (CL)** The nose direction, at the time that CL is set, will remain the forward direction regardless of how the orientation and position of the aircraft changes. This will remain fixed until you reset it or exit CL mode. 

### Home Lock (HL)* Record a Home Point (HP) and enter HL mode. The forward and backward controls will move the aircraft farther from and closer to the established Home Pont, regardless of how the orientation and position of the aircraft changes. 

### Point of Interest (POI)* Point of Interest. Record a point of interest (POI). The aircraft can then circle around the POI and the nose wi ll always points toward the POI.**Note: *** Home Lock and Point of Interest feature are coming soon.

IOC Requirements IOC is only available under the following conditions:



## Using IOC Toggle the Flight Mode Switch F - mode and follow the instructions prompted on the DJI Pilot app to select the desired IOC mode. 

## Po**we r**  DJI Intelligent Flight Battery The DJI Intelligent Flight Battery has a capacity of 4480 mAh, a voltage of 15.2 V, and a smart charge/ discharge functionality. It should only be charged using an a ppropriate charger that has been approved by DJI. **? A bout LIPO Batteries:**  These batteries have three main things going for them that make them the perfect battery of choice for the Phantom over conventional rechargeable batteries.

 **Light weight** and can be made in almost any shape and size.  **Large capacities,** meaning they hold lots of power in a small package.  **High discharge** abilities capable of meeting the demanding power requirements of the UAV’s. On the downside the batteries are still fairly expens ive compared to NiCad and NiMH, but coming down in price all the time. Although getting better.

 Another issue is that **they don’t last that long** , perhaps only 400 charge cycles (much less if not cared for properly). That said, they are getting better all the time, especially if cared for properly.  **Safety**

**issues** - because of the volatile electrolyte used in LiPo’s, they can catch fire or explode. The DJI Smart Battery concept with the built in balancer and charger has reduced the risk of some of the handle dangers, but regardless, Lipo batteries demand your respect.  **Require unique and proper care** if they are going to last for any length of time mor e so than any other battery technology. Charging, discharging, and storage all affect the lifespan

–one mistake and serious damage can be done. 

### DJI Intelligent Flight Battery Functions 1. Battery Level Display: the LED indicators display the current batter y level.2. Battery Life Display: the LEDs display the current battery power cycle.

3. Auto - Discharging Function: To prevent swelling, the battery automatically discharges to below 65% of total power when it is idle for more than ten days. It takes around two days to discharge the battery to 65%. It is normal to feel moderate heat being emitted from the battery during the discharge process. Discharge thresholds can be set in the DJI Pilot app. 4. Balanced Charging: Automatically balances the voltage of each battery cell when charging. 5. 5. Overcharge Protection: Charging automatically stops when the battery is fully charged. 6. 6. Temperature Detection: The battery will only charge when the temperature is between 0°C (32°F) and 40°C (104°F). 7. 7. Over Current Protection: The battery stops charging when high amperage (more than 8 A) is detected. 8. 8. Over Discharge Protection: To prevent over- discharge damage, discharging automatically stops when the battery voltage reaches 12 V. 9. 9. Short Circuit Protection: Automatically cuts the power supply when a short circuit is detected. 10. Notice: The Intelligent Flight Battery must be fully charged before using it for the first time. Refer to 11. "Charging the Intelligent Flight Battery" for more information. 12. 10. Battery Cell Damage Protection: The DJI Pilot app displays a warning message when a dam aged 13. battery cell is detected. 14. 11. Battery Error History: Browse the battery error history in the DJI Pilot app. 15. 12. Sleep Mode: To save power, the battery enters sleep mode after 20 minutes of inactivity. 16. 13. Communication: Information pertaining to the battery’s voltage, capacity, current, etc. is transmitted to 17. the aircraft’s main controller. 

### Using the Battery **Turning ON/OFF Turning On:**  Press the Power Button once, then press again and hold for 2 seconds to turn on. The Power LED will turn red and the Battery Level Indicators will display the current battery level. **Turning Off:** Press the Power Button once, then press again and hold for 2 seconds to turn off. The battery power LED will flash wh en powering off the Phantom to allow automatically stopping of a recording during the event recording wasn’t stopped. 

### Checking the Battery Level The Battery Level Indicators display how much power remains. Wh en the battery is turned off, press the Power Button once. The Battery Level Indicators will light up to display the current battery level. See below for details.

### Charging the Intelligent Flight Battery

1. Connect the Battery Charger to a power source (100 - 240 V 50/60 Hz). 2. Open the Prote ction Cap and connect the Intelligent Flight Battery to the Battery Charger. If the battery level is above 95%, turn on the battery before charging. 3. The Battery Level Indicator will display the current battery level as it is charging. 4. The Intelligent Flight Battery is fully charged when the Battery Level Indicators are all off. 5. Air- cool the Intelligent Flight Battery after each flight. Allow its temperature to drop to room temperature before storing it for an extended period. **Caution:** Do not charg e the Intelligent Flight Battery and remote controller with the standard charger at the same time, otherwise the charger may overheat.**Warning:** Always turn off the battery before inserting it or removing it from the Phantom 3.

Never insert or remove a battery when it is turned on. After these issues are resolved, press the Power Button to turn off the Battery Level Indicator. Unplug the Intelligent Flight Battery from the charger and plug it back in to resume charging. Note that you do not need to unp lug and plug in the charger in the event of a room temperature error; the charger will resume charging when the temperature is within the allowable range. DJI does not take any responsibility for damage caused by third - party chargers. 

### How to discharge your **Intelligent Flight Battery: Slow :**  Place the Intelligent Flight Battery into the Phantom 3 Professional’s Battery Compartment and turn it on. Leave it on until there is less than 8% of power left, or until the battery can no longer be turned on. Launch th e DJI Pilot app to check battery levels. **Rapid :** Fly the Phantom 3 Professional outdoors until there is less than 8% of power left, or until the battery can no longer be turned on. Note: Be aware that the output power of the supplied Phantom 3 Professional charger is 100W

. **Comment:** Flying is surely the fastest way to discharge a battery. However, your Phantom might drop from the sky if it does not land itself in time when the battery is low. For that reason, I do not recommend anyone ever try to completely discharge a battery by flying the Phantom until the battery is in a dangerously low state. If you value your investment, you should always land at or before the battery reaches the low level. 

### Cold Weather Operation: 1. Battery capacity is si gnificantly reduced when flying in low temperature (< 0°C) environments. 2. It is not recommended that the battery be used in extremely low temperature (< - 10°C/14F) environments. Battery voltage should reach the appropriate level when operating environment with temperatures between - 10°C and 5°C. 3. End the flight as soon as the DJI Pilot app displays the “Low Battery Level W arning” in low temperature environments. 4. Keep the battery indoors to warm it before flying in low temperature environments. 5. To ensure optimal performance of the battery, keep the battery temperature above 20°C/68F. 6. The charger will stop charging the battery if the battery cell’s temperature is not with in the operating range (0°C/32F ~ 40°C/104F ). **Important:** In cold environments, insert the battery into the battery compartment and allow the aircraft for approximately 1 - 2 minutes to warm up before taking off.**Battery**

**life** Battery life refers to how many more times the battery can be discharged and recharged before it must be replaced. When the battery is turned off, press and hold the Power Button for 5 seconds to check the battery life. The Battery Level Indicators will light up and/or blink for two seconds, as shown below:

Wh en battery life reaches 0%, it can no longer be used. Wa rning: W hen battery life reaches 0%, it can no longer be used. 

### Battery Protection LED Display The table below shows battery protection mechanisms and corresponding LED patterns.



## Safety Guidelines To avoid fire, serious injury, and property damage, observe the following safety guidelines when using, charging, or storing your batteries.

### Battery Use

 Do NOT allow the batteries to come into contact with any kind of liquid.  Do NOT leave batteries out in the rain or near a source of moisture.  Do NOT drop the battery into water. If the inside of the battery comes into contact with water, chemical decomposition may occur, potentially resulting in the battery catching on fi re, and may even lead to an explosion.  Never use non - DJI batteries. Go to www.dji.com to purchase new batteries. DJI takes no responsibility for any damage caused by non - DJI batteries.  Never use or charge swollen, leaky, or damaged ba tteries. If your batteries are abnormal, contact DJI or a DJI authorized dealer for further assistance.  Never install or remove the battery from the aircraft when it is turned on. Do NOT insert or remove batteries if the plastic cover has been torn or comp romised in any way.  The battery should be used in temperatures from - 10 °C to 40 °C . Use of the battery in environments above 50 °C can lead to a fire or explosion. Use of battery below- 10 °C can lead to permanent damage 6) Do NOT use the battery in strong electrostatic or electromagnetic environments. Otherwise, the battery control board may malfunction and cause a serious accident during flight.  Never disassemble or pierce the battery in any way or the battery may leak, catch fire, or explode.  Electrolytes in the battery are highly corrosive. If any electrolytes make contact with your skin or eyes, immediately wash the affected area with fresh running water for at least 15 minutes, and then s ee a doctor immediately.  Check the condition of the battery if it falls out of the aircraft. Make sure the battery is NOT damaged or leaking before putting it back into the aircraft.  If the battery falls into water with the aircraft during flight, take it out immediately and put it in a safe and open area. Maintain a safe distance from the battery until it is completely dry. Never use the battery again, and dispose of the battery properly as described in the Battery Disposal section below.  Do NOT heat batteries. Put out any battery fire using sand or a dry powder fire extinguisher. Never use water to put out a battery fire.  Do NOT put batteries in a microwave oven or in a pressurized container.  Do NOT place loose battery cells on any conductive surface, suc h as a metal table.  Do NOT put the loose cells in a pocket, bag or drawer where they may short- circuit against other items or where the battery terminals could be pressed against each other.  Do NOT drop or strike batteries. Do NOT place heavy objects on th e batteries or charger. Avoid dropping batteries.  Clean battery terminals with a clean, dry cloth. 

### Battery Charging  Do **NOT** attach the batteries to wall outlets or car charger sockets directly, and always use a DJI approved adapter. DJI takes no responsibi lity if the battery is charged using a non - DJI charger.  Never leave the battery unattended during charging. Do NOT charge the battery near flammable  Materials or on flammable surfaces such as carpet or wood. Do NOT charge battery immediately after flight, because the battery temperature may be too high.  Do NOT charge the battery until it cools down to near room temperature. Charging the battery outside of the temperature range of 0 °C -40 °C may lead to leakage, overheating, or battery damage. 2) Disconnect the charger when not in use. Examine the charger regularly for damage to

the  cord, plug, enclosure, or other parts. Do NOT clean the charger with denatured alcohol or other flammable solvents. Never use a damaged charger.  Charge and discharge the battery completely once every 20 charge/discharge cycles. Discharge the battery until there is 8% remaining power or until it can no longer be turned on, then recharge it to the maximum capacity. This power cycling procedure will optimize battery life.  The Intelli gent Flight Battery is designed to stop charging when it is full. However it is a good practice to monitor the charging progress and disconnect the batteries when fully charged. 

### Battery Storage  Keep batteries out of the reach of children and pets.  Do NOT leave the battery near heat sources such as a furnace or heater. Do NOT leave the batteries inside of a vehicle on hot days. The ideal storage temperature is 22 °C - 28 °C

.  Keep the battery dry. Never drop the battery into water.  Do NOT drop, strike, impale, or manually short- circuit the battery.  Keep the battery away from metal objects such as glasses, watches, jewelry, and hairpins.  Discharge the battery to 30% - 50% if it will NOT be used for 7 days or more. This can greatly extend the battery life.  The battery automatically discharges to below 65% when it is idle for more than 10 days to prevent it from swelling. It takes approximately 2 days to discharge the battery to 65%. It is normal that you may feel moderate heat emitting from the battery during the discha rge process. Set the discharging thresholds in the DJI Pilot app.  The battery will enter hibernation mode if depleted and stored for a long period. Wh en in hibernation mode, if you try to power on the battery, the battery power LED will show a solid red li ght and the battery level LEDs will all be off. You cannot manually turn off the battery power LED in this state. Leave the battery unattended for 5 minutes, and then the light will turn off. Recharge the battery to bring it out of hibernation.  Remove batteries from the aircraft when stored for an extended period. 

### Battery Disposal Dispose of the battery in specific recycling boxes only after a complete discharge. Do NOT place the battery in regular trash containers. Strictly follow your local regulations regarding the disposal and recycling of batteries. Note: If the power on/off button on the Intelligent Flight Battery is disabled and the battery cannot be fully discharged, please contact a professional battery disposal/recycling agent for further assista nce. 

### Battery Maintenance  Never use the battery when the temperature is too high or too low.  Never store the battery in environments with a temperature higher than 60 °C

.  Never over- discharge, as this may lead to battery cell damage.  Battery life may be reduced if not used for a long time.

### Battery Use

1) Make sure the batteries are fully charged before each flight. 2) It is recommended that you do NOT charge the Intelligent Flight Battery and remote controller at the same time. 3) Land the aircraft immed iately when the low battery level warning activates in the DJI Pilot app. **Travel Notice** - Before carrying the Intelligent Flight Battery on an airline flight, it must first be fully discharged. This can be done by using your aircraft until the battery is d epleted. Only discharge the battery in a fireproof location. 

## Propellers **Propellers** Use only DJI approved propellers with your Phantom 3 Professional. The grey and black nuts on the propeller indicate where they should be attached and in which direction they should spin. To attach the propellers properly, match the nut color with the motor axis color.

# At**taching the propellers**

Be sure to remove the warning stickers from the motors before attaching the props.

 The black and silver tipped motors spin in opposite directions -- which is why you need two of each prop. W hen installing your props, make sure the black topped props go on top of the black topped motors -- and the same for the silver tops.  Ensure propellers are attached to its corresponding motors , otherwise the aircraft cannot take off.  Hand tighten each of the propellers on the corresponding motors to ensure it is attached firmly

. **Detaching the Propellers**

 Hold the motor in place with one hand, then spin the propeller in the indicated unlock direction.  Check that the propellers and motors are installed correctly and firmly before every flight.  Ensure that all propellers are in good condition before each flight. DO NOT use aged, chipped,  or broken propellers.  To avoid injury, STAND CLEAR of and DO N OT touch propellers or motors when they are spinning.  ONLY use original DJI propellers for a better and safer flight experience. P3 are model 9450 self tightening. P3 props are not interchangeability with P2 props as they a specially made to not spin off when dynamic braking is initiated by the aircraft Prop Balancing video https://youtu.be/OXuNnYQO2s4 

### DJI Phantom 3 **- RTH**  **- Return to Home**  

## What Is RTH The Return - to - Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH procedures: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail. 

## RTH Modes **Smart (RTH)** Use the RTH button on the remote controller or tap the RTH button in the DJI Pilot app and follow the on - screen instructions when GPS is available to initiate Smart RTH. The aircraft will then automatically return to the last recorded Home Point. You may use the remote controller’s control sticks to control the aircraft’s position to avoid a collision during the Smart RTH process. Press and hold the Smart RTH button once to start the process, and press the Smart RTH button again to terminate the procedure and regain full control of the aircraft.

### Low Battery (RTH)

The low battery level failsafe is trigg ered when the DJI Intelligent Flight Battery is depleted to a point that may affect the safe return of the aircraft. Users are advised to return home or land the aircraft immediately when prompted. The DJI Pilot app will display a notice when a low battery warning is triggered. The aircraft will automatically return to the Home Point if no action is taken after a ten - second countdown. The user can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds for these warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point. The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. The u ser can still use the remote controller to alter the aircraft’s orientation during the landing process. **Caution:** Wh en Critical battery level warning is triggered and the aircraft begins to land automatically, you may push the throttle upward to make the a ircraft hover at its current altitude, giving you an opportunity to navigate to a more appropriate landing location. The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time. They are automatically adjusted according to the aircraft’s current location and status. **Failsafe** 

### (RTH) If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically be activated if the remote controller signal is lost for more than three seconds. The Return - to - Home process may be interrupted and the operator may regain control of the aircraft if the remote controller signal connection is re established. **Warning:** The aircraft cannot avoid obstruction during the Failsafe RT H, therefore, it is important to set an suitable Failsafe altitude before each flight. Launch the DJI Pilot app and enter “Camera” and select “MODE > Advanced Settings > Failsafe mode” to set the Failsafe altitude. The aircraft will stop its ascent and ret urn to the Home Point immediately if the throttle stick is moved during the Failsafe RTH procedure.

## What is the VPS and how does it work

The DJI Vision Positioning System uses ultrasound and image data to he lp the aircraft maintain its current position. Wi th the help of Vision Positioning, the P3 can hover in place more precisely and fly indoors or in other environments where a GPS signal is not available. The main components of the Vision Positioning System are located on the bottom of your Phantom 3 Professional; they include [2] two ultrasonic sensors and [1] one monocular camera. This system combines visual data and sonar waves in a single unit, detecting both variance in patterns on the ground and curren t altitude. Wi th this information, the P3 can hover in place without GPS assistance provided it can work properly with the conditions that is is operating in. This VPS is a very sophisticated and accurate system if used within it’s design limits. Please read all of the warnings, notes, and cautions associated with this device.



## What affects VPS accuracy Using VPS By default the Vision Positioning System is activated automatically when the Phantom 3 is turned on. No further action is required. Vision Positioning is typically used in indoor environments, where GPS is unavailable. Using the sensors that are built into the Vision Positioning system, the Phantom 3 can hover precisely even without GPS. 

## Checking the status of the VPS - Pilot App VPS Indicator On the Pilot App main camera interface, you will notice a small VPS indicator icon that shows the P3 distance above ground level.

## Turning ON/OFF VPS

Turn on VPS by selecting General Settings>Advanced Settings>Enable VPS ON/OFF **Operating Note:** If you intend to use VPS, place the aircraft on a flat surface that has a clear pattern variation. 3. Turn on the aircraft. The aircraft status indicator will flash green two times, which indicates the Vision Positioning system is ready and you should see the VPS status icon on the main screen**Warning:** Wh ile the VPS System can be a very helpful device for indoor flying under the

proper conditions, make sure you read and understand its application and limitations. Wh en flying outdoors, it may introduce input errors that could lead to unexpected flight ope rations. Since the VPS has limited use when flying outdoors, some pilots will turn it off and leave it off unless they intend to fly the P3 indoors and understand the conditions that may cause erratic flight behavior, even indoors.

**Warning:** The per

formance of your Vision Positioning System is affected by the surface over wh ich it is flying. The ultrasonic sensors may not be able to accurately measure distances when operating above sound - absorbing materials. In addition, the camera may not function correctly in suboptimal environments. The aircraft will switch from P - mode to A- mode automatically if neither GPS nor Vision Positioning System are available. Operate the aircraft with great caution in the following situations:  Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).  Flying over a highly reflective surfaces. Flying at high speeds(over 8 m/s at 2 meters or over 4 m/s at 1 meter).

 Flying over water or transparent surfaces.  Flying over moving surfaces or objects.  Flying in an area where the lighting changes frequently or drastically.  Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.  Flying over surfaces that can absorb sound waves (e.g. thick carpet).  Flying over surfaces without clear pa tterns or texture.  Flying over surfaces with identical repeating patterns or textures (e.g. tiles with the same design).  Flying over inclined surfaces that will deflect sound waves away from the aircraft. **Operating Note:**  Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness of the sensors.  Vision Positioning is only effective when the aircraft is at altitudes of 0.3 to 3 meters.  The Vision Positioning System may not function properly when the aircraft is flyin g over water.  The Vision Positioning System may not be able to recognize pattern on the ground in low light conditions (less than 100 lux).  Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning system is in operation.  Vision Positioning System may not be able to stabilize the aircraft when flying close to the ground (below 0.5 meters) at fast speeds.  Keep the animals away from the aircraft when Vision Positioning system is activated. The sonar sensor emits high frequency sound s that are only audible to some animals. 

## Pilot App VPS Indicator On the Pilot App main camera interface, you will notice a small VPS indicator icon that showd the P3 distance above ground level.

## Compass Calibration

### Overview

This document reviews the process to calibrate the navigational compass on the DJI Phantom UAV. In this lesson, you will learn:  

### How the compass works  

### Compass location  

### Wh y compass calibration is necessary  

### Wh en to perform a compass calibration  

### Wh at to do if calibration fails 

### How the Phantom 3 compass works Wh ile the GPS system on the Phantom 3 does a great job at locating the Phantom both geographically and vertically, it cannot tell which way the nose is pointed. The Flight Control Computer on the Phantom needs to know which direction the nose is pointing in order to be able to properly give the correct control commands received from the pilot. The Phantom must also transmit this information the the Pilot App for orientation display on the radar. 

### Compass Location The Phantom compass is located on the rear lower left leg as you look at the aircraft from the front. The instrument is wired from this location up into the sensor IMU unit for data processing. The compass is designed to operate in this location so it will be as far away from the magnetic fields of the spinning motors and power distribution wires as possible. Wi th the compass be ing located out on a leg like it is, it is susceptible to magnetic fields from exterior sources. Since the compass is essentially a magnet itself, its magnetic field interacts with any close by magnetic fields that it comes close with. Note: The compass i s calibrated for the left rear leg of the copter and it must be fixed in the direction that it is mounted so that it is pointing forward. If you move it for some reason, it still needs to face forward. 

### What affects compass accuracy External magnetic fields are present in metal and electronic objects, including cell phones, automobile bodies, even rebar in the concrete floor or parking lot. All these items contain magnetic fields that could affect compass accuracy if brought too close to the aircraft. Note : unless the field is extremely powerful, the magnetic field of the compass will return to its normal position once the Phantom is moved away from the particular influence.

### Why compass calibration is necessary

The compass is very sensitive to electromagnetic interference, which can produce abnormal compass data and lead to poor flight performance or flight failure. Regular calibration is required for optimal performance. The compass needs to accurately sense the earth's magnetic field and only the earth's field. Wh en it has been exposed to any other field, it’s ability to sense the earth's field may become inaccurate. It is good practice to first of all be aware of where the compass is located on the aircraft and avoid getting it close to stro ng magnetic fields that may affect its own magnetic field. This of course isn’t always possible and calibration is necessary. Caution: the compass can also be influenced by magnetic fields when in flight, therefore, it is prudent to keep some distance fro m influencing forces. 

### When to perform a compass calibration Wh ile the aircraft's internal programming will sense a need for compass calibration, it is a good idea to perform a calibration when:  Aircraft Status Indicator lights are blinking green and yell ow .  The Pilot APP alerts you of the need for calibration You fly from a new flight location or in a location that is different from the most recent

flight.  There had been a modification to the Phantom including firmware updates or physical changes.  Wh en severe drifting occurs in flight or the aircraft does not fly in straight line. 

### Calibration Procedures Choose an open area to carry out the following procedures. 1. Tap the Aircraft Status Bar in the app and select “Calibrate”, then follow the on - screen inst ructions.

2. Put the remote controller down and take a few steps away, make sure there are no magnetic fields or metal objects in the area. 3. Hold the aircraft horizontally, the indicator lights will flash yellow. Rotate 360 degrees. The Aircraft Status Ind icators will display a solid green light.4. Hold the aircraft vertically, with nose pointing downward, and rotate it 360 degrees around the

center axis. The indicator lights will turn off

. 5. If the Aircraft Status Indicator blinks red and yellow after the calibration procedure, move your aircraft to a different location and try again.**Caution**

 Do not calibrate your compass where there is any possibility of strong magnetic interference.  Sources of potential interference include magnetite, parking structures, and subterranean metal structures  Do not carry ferromagnetic materials with you during calibration such as keys or cellular phones.  Do not calibrate in direct proximity to large metal objects.  DO NOT calibrate indoors. 

## IMU Calibration Overview This document reviews the process to calibrate the Inertial Measurement Unit IMU of the DJI Phantom UAV. In this lesson, you will learn:  

### Wh at is an IMU and how does it work  

### Wh at affects IMU Accuracy  

### Wh en to perform an IMU calibration  

### How to perform an IMU calibration  

### Wh at to do if IMU calibration fails **What is an IMU and how does the w**  **ork** The IMU in the Phantom 3 works by detecting the current rate of acceleration using micro accelerometers, and detects changes in rotational attributes like pitch, roll and yaw using micro gyroscopes. The compass (magnetometer) assists to counter orientation drift. For the aircraft to be able to stay level. it needs to know what level looks like - and needs to be reset occasionally for it to shed any accumulated error. Inpu ts from the IMU also allow the camera to hold steady on the horizon, which is a very difficult task, give the constant aircraft adjustments and vibrations. If you would like more info on the IMU, READ MORE HERE 

## When to perform an IMU Calibration Wh ile IMU calibration is not performed that often, it should be one of the first things you look at when troubleshooting a problem or when performing routine maintenance. The IMU accumulates small errors as time goes on and need to be occasionally reset to perfect level.  Wh en drifting and instability becomes apparent  After Firmware Updates  Camera horizon is not level  Receive an alert notice from the P3 MC that calibration is needed. 

## Calibration Procedures 1. Turn on the Remote Controller, Phantom and tablet/phone. Connect the remote controller to the tablet/smartphone with the appropriate cable.2. Enter the Pilot App and navigate to the IMU calibration page b y going to: DJI Pilot app

>Camera> MC Settings > Sensors > IMU calibration. 3. Start the IMU Calibration, click through the message and warning screens. The IMU Calibration will take 3 - 10 minutes - Notification messages will pop up as calibration procedes. Ensure you get an IMU Calibration complete message.**Operating Note:** IM U calibration should be considered routine maintenance and

accomplished when it needs it and at scheduled intervals, much like a tire rotation on your car.

**Caution:**  Before starting the IMU Calibration, the P3 should be as cool as possible. Not freezing, but cool. Also, not recently flown (give it an hour to cool off). Remove the battery and let it sit in a cool room if possible, removing the battery will help it cool down qu icker, of course you will need to reinstall the battery before you start. Remember, this procedure isn’t done that often, but, needs to be done right. The P3 must be sitting on a firm, perfectly level surface with no vibrations.

 You must not touch, bump or move the P3 during the IMU calibration process and you should minimize/avoid any floor vibrations (people walking nearby, doors slamming, dogs kids running through the room etc.).

**Operating Note:** After a successful IMU calibration, while the P3 is still sitting on the level surface, is a good time to proceed and do a Gimbal Auto Calibration. Going outside and performing a compass calibration is also a good idea. The image below shows the sensor readings after a good calibrations. the Gyroscope M OD reading should be near 0, and the Acceleration MOD reading should be right around 1.0. Compass MOD 1400 - 1600

## What to do if IMU Calibration fails

If IMU calibration fails, power down the P3, let it cool off and start over

### SECTION 4

**– Flight**  **Training PURPOSE OF FLIGHT TRA** **INING** The overall purpose of primary and intermediate flight training is the acquisition and honing of basic airmanship skills as they pertain to operating the Phantom. Airmanship can be defined as: • A sound acquaintance with the principles of UAV flight. • The ability to operate a UAV with competence and precision in different settings and conditions. • The exercise of sound judgment that results in optimal operational safety and efficiency of the aircraft. Learning to fly a Phantom is not an easy feat. Since an Phantom operates in a three dimensional environment it requires a type of motor skill development that is more sensitive to this situation such as:

• **Coordination**

—The ability to use the your hands subconsciousl y and in the proper relationship to operate the control transmitter sticks, switches, and levers in a manner thataccurately controls the Phantom.

• **Timing**

—The application of muscular coordination at the proper instant to make flight, and all maneuvers in cident thereto, a constant smooth process without looking at the controls. • **Control touch**

—The ability to sense the action of the copter and its probable actions in the immediate future, with regard to attitude and speed variations. Unlike a pilot siting the the aircraft, you do not have the ability to feel the aircraft movement, so, your eyesight is more important than ever. The goal that comes through proper training and practice is that the pilot becomes one with the Phantom, rather than a just machine operator. This is where aircraft systems knowledge, simulator training, and a structured flight training program combine into a well trained pilot. It does not come easy and like anything else in life, you get out what you put into it. An accomplished pi lot demonstrates the ability to assess a situation quickly and accurately and deduce the correct procedure to be followed under the circumstance; to analyze accurately the probable results of a given set of circumstances or of a proposed procedure; to exercise care and due regard for safety; to gauge accurately the performance of the Phantom; and to recognize personal limitations and limitations of the aircraft and avoid approaching the critical points of each. The development of airmanship skills require s effort and dedication on the part of the pilot, beginning with the very first training flight where proper habit formation begins by using good operating practices. The underlying purpose of flight training is to develop skills and safe habits that are transferable to any UAV. Basic airmanship skills serve as a firm foundation for this. The pilot who has acquired necessary airmanship skills during training, will easily advance to more technical skills. The goal of flight training is a safe and competent pilot. Every flight should be considered a training flight consisting of a well thought out plan, a set of goals, and a post flight evaluation of lessons learned. **Basic Flight Training -**  **Maneuvers** This section describes a series of basic flight maneuvers that should be mastered before preceding further. W hile the addition of the flight navigation systems adds a great measure of ease and confidence to flying the Phantom, the following procedures are critical to basic skills and should be practiced in on on going basis. Take your time and practice these maneuvers until you can do them without hesitation. If you practice the same maneuver on a flight simulator and than proceed to practice with the Phantom, your training will be much accelerated. **Exercise 1 -**  **Takeoff and Landing** Double check that the conditions for flying are still safe (no people entered the flying area without you noticing as you were focused on the model, nose of model is pointing away from you and into the wind, nothing hanging loose from the model)If the flying conditions are still OK, switch the motor on, do not use auto - take - off for this

exercise. Increase the throttle stick until the model gets light on its feet. Time for lift- off! Increase the throttle stick a little bit faster so that the Phantom quickly lifts off. You want it to go to an altitude of 3 feet or more to get out of ground turbulence caused by the downward airflow from the propellers. Once you are at 5 - 10ft, gradually reduce the throttle to slow down the ascent, and gradually decrease it further to descend slowly land again. Do NOT suddenly decrease the throttle or you will crash. If you start descending too quickly, increase the throttle a little bit to slow down the descent. Unfortunately the very sensors that the Ph antom uses to keep it level etc will cause it to 'bunny hop' if you are not careful. Basically the Phantom behaves differently as it gets closer to the ground due to ground effect. That is the downwash of the props against the ground affecting the lift and stability. W hat you need to do is to bring the Phantom down to about 3 feet then slowly descend keeping the aircraft level, once you are just about to touch the ground reduce the throttle completely. If you reduce it slightly it will bounce, the sensor wi ll increase the gas and it will rise, you will then reduce the gas, the sensor will also reduce the gas and it will bounce again and so on. Reducing the gas completely means the sensor's input is not enough to give it enough lift to keep it in the air. Kee p the left stick completely down for a few seconds and it will shut off the motors. If the copter drifts a bit during this phase, just re - position it on the ground between take - offs. We 're not yet going to try flying it back to its position. Practice lift- off and landing repeatedly until you can fully control it and landings are soft and smooth. Reduce the throttle to idle between landings and recheck the environment! If for some reason something goes wrong and the copter lands on its side or upside down, IMMEDIATELY turn off the motors (throttle stick full down) to avoid unnecessary damage to ESCs, propellers or motors. Reposition it, and check for damage. Reposition yourself and recheck the environment. Restart the motors and restart lift- off and landing practice. Remember: **Small stick movements!** If you can't get the Phantom back to its starting position, it is safer for both the copter and yourself to land, manually reposition it and restart, rather than to continue to try and correct drift wh ich could lead to disorientation followed by crashing the model into the ground or yourself. **Exercise -** **2** - **Hovering ATTI**  **- mode**  - Once you are comfortable with takeoff and landing, it’s time to practice one of the important maneuvers, hovering. Wi th the Phantom pointe d away from you and at chest height to avoid ground effect, hold the aircraft in a hover. Wi th the nose continuing to point away from you, lightly maneuver roll left and right, and pitch fore and aft. Practice this for 10 minutes or until your battery ge ts low. This is called nose - out flying and is the easiest way for new pilots to get a good feel for the aircraft. Mo ving left or right, or forward or aft is of course great. But the big advantage of a Phantom is that it can hover. It can hang still above a given point. Hovering an UAV means that in additionto the self- stabilization by the flight controller you provide some additional control inputs to keep

the copter over the same spot on the ground at the same altitude. Carefully combing the roll, nick, yaw and throttle inputs to correct drift in any of these four axis, trying to keep the model in a stable hover at between 1 and 2 meters above its take - off position. If the craft moves too far out of the hover area, just land and reposition it. Hovering is a very critical flying skill so practice it extensively. It may require several hours of practice under different conditions to master it to such a degree that even in some wind you can keep the model within 20cm of its intended hovering position. If yo u can do this well, you will most likely be able to get out of trouble during other maneuvers by going into a hover quickly, reassessing the situation, and flying to a safer position or landing spot. At first, just practice over the general area of your s tarting point. Later consider marking a point on the ground (e.g. a helipad made from plywood or canvas, or a pylon or plastic bottle) and hover exactly above that point. You may be surprised how difficult it can be to stay correctly above a clearly marked spot for several minutes. Once you can control the Phantom left/right and forward/backward, do some practice on rudder / yaw. From a hover position, carefully move the rudder stick to turn the nose of the copter approx 45 degrees to the left or right, an d then yaw back. You do not yet want to go further than 60 - 70 degrees because you will quickly run into control reversal and get disoriented. Exercise - 3 House pattern A typical flying maneuver is the "house". Lift- off, at about breast height hover for ab out 5 seconds, then fly 3 -4 meters sideways, again hover for about 5 seconds and land. Then do the same in opposite direction. Keep the nose pointing away from you (tail - in). Exercise -4 - Sq uare - Flying **Fly along the borders of a square and break at the edg**  **es for about 5 seconds. Chose a height about 6 feet and a side**  **- about 6 feet in length. The nose always points a** **way from**  **the pilot's position. Repeat this exercise for 15 -** **20 minutes.** Exercise - 5 Hover Sideways **Its very important to break the habit of the fix** **ed view to y our copter. Think like y** **ou w ere**  **hovering in the model and from the left to the right side. Turn the nose in flight -**  **direction and than gradually** 

**bring it to 90 degrees from there. If y ou loose orientations, bring the**  **nose back to the starting po sition and try**  **again.** Exercise - 6 Square pattern Mark four corners of a 3 to 5 meter square around your lift- off position. Lift- off, hover for 5 seconds, and then fly the shortest line to the first corner. Hover above this corner for 5 seconds and then fly to the next corner in a direct line, hover for 5 seconds, etc. Do this in both directions (clockwise and counter- clockwise). You may have a clear preference but should be able to do this in both directions. Also occasionally fly across diagonally from one corner to the opposite. Make sure you do this purposefully: have a flight plan and don't adapt going from one corner to the diagonal corner instead of the next because you drifted off a bit and it looks so sloppy if you have to fly a curve instead of a st raight line. During movement from one corner to another keep the nose directed away from you. Fly at a constant altitude (about chest height). Try flying at aconstant speed. Keep the speed low to allow easy transition to hover without overshooting the

mark. Exercise - 7 Circles **Plot out or envision a 50 ft circle on the ground, Take off and fly the circle alternating**  **clockwise and counter clockwise. Practice with the nose pointing a way**  **from y ou (Nose**  **** **out). Exercise**  **- 8 Nose Flying Side** **way s**  Once you have maste red flying house and square patterns "tail in", it is time to start gradually getting used to flying the Phantom more from the models' perspective. So repeat the above house pattern, but now when preparing to move sideways, in the hover yaw (turn) the nose a bit (30 - 60 degrees) in the direction you will be flying in, and then try flying the same straight line that you could fly so nicely "tail in". Repeat this until you can comfortable turn the nose the full 90 degrees in the direction you want to fly in an d not confuse the roll and nick directions. Once you can fly the house pattern nose sideways, you can also practice the square. However when moving back towards you, either yaw the model so that it is again nose - out, or fly it sideways (alternate this according to your "flight plan"). **Tip:** Flying nose sideways can be easier if you also turn your body sideways a bit. In fact you will then be flying tail - in again but with the model to your left or right. This trick does not help much in the transition to no se - in flying. But keep in mind if you get into trouble during flights later on due to some disorientation. It may help you recover. Exercise - 9 The walk- along For the walk- along you walk along a path with the MK tagging along at a fixed position in front, or next to you. If you reach a corner, of course you must yaw the MK to be tail - in or nose - in or sideways again, whichever mode of flying you want to practice. Of course you do have to make sure there are no other people walking the path. Practical use of this exercise is mainly in the RCAP arena where you often do walk around a bit to change your position and that of the model to take pictures from a different angle. Also the change in relative positions between you and the model forces you to focus on the model and not orientate your control movements to the position of the model relative to its surroundings. Exercise 10 - The circle me For the circle me, the intent is to fly a full circle around yourself, or another given target, at a fixed distance and yawing at a same angular rate as the craft is moving through the circle. So if you fly it tail - in, the craft should be looking straight out from the circle (and if shooting video this would result in a wide panorama). If flying nose - in it should be looking you in the eye at all times. Try to also maintain a constant altitude during this exercise. And make sure that there are no people standing anywhere near you if you do this at practice hover altitudes (1 - 2 meters). This is again an exercise which is usefu l later on for RCAP flying. However it also helps improve control of left and right sticks. Exercise - 11 Flying nose - in The most difficult way of flying is with the models nose pointed at you. Once you have mastered flying nose sideways, you're almost there

.There are now two ways to progress.

1.You can restart hovering practice but now lifting off with the models' nose pointed at you. The advantage of this approach is that you learn to transition well from nose in to hover to flight and vice versa, a crit ical ability to get out of trouble. If you start with hovering nose - in just repeat the house and square patterns after that. 2. Alternatively you can gradually progress from nose - sideways flying the house and square fi gures to flying them with nose in the direction of flight at all times, and eventually to fully nose in (i.e. flying away from you with the noise pointing at you, and flying from left to right or right to left with the nose pointing at you). Before you do this, practice 360 degree yaw in both directions from normal tail - in hover. In all cases make sure you practice flying the square nose - in in both directions (clockwise and counter- clockwise). Practice nose in flying very, very extensively. You must eventually be able to transition from tail in to nose - sideways to nose - in flying without any hesitations or mistakes with respect to control inputs for flying your intended pattern / direction, and transition at a moment’s notice to a hover. If you have trouble controlling the aircraft nose - in at s ome point, just yaw it back tail - in and regain hover position. Never panic and pull the throttle down !!! If necessary, slightly increase the throttle to remain between 1 and 2 meters above the ground until you have been able to regain hover. If all else f ails, very carefully decrease the throttle and land. **Tip:** Until you have mastered nose - in flying, do NOT attempt either aerial photography or aerobatic flying. Not having mastered this skill properly will eventually cost you your camera or model.

## Inflight Standards

 Do not take risks! Your own safety and that of your environment depend on the good behavior of the pilot.  Always keep a distance from people, animals and objects. Improper operation can cause serious injury and property damage!  Never fly towards viewers and avoid overflights of spectator  Keep in mind that viewers could get close to the Phantom, without being aware of potential dangers  Always turn off the Phantom 3 first and disconnect the flight battery before turning off the transmitter  Only fly in sigh t. In the case of a manual control, you must be able to see the position and attitude  Never rely 100% on functions such as GPS, compass, or altitude control. You must always be able to take manual control of the Phantom  Reduce the gas or switch off the motors in case of a crash or failure  Do not fly in blocked air space, such as in the vicinity of airports, etc.  Pay attention to undervoltage warning - a flight to empty battery can cause damage to the Smart Battery and crash.  If a defect or malfunction has occurred, it must be corrected before the next start 

## Post Flight

 Disconnect the battery  Check for damage  Make sure that the propellers are not damaged  See the Handling and safety precautions of Lipo batteries  After a crash the sensors and electronics might be damaged. Before the next start everything must be checked 

## Cold Weather Flying **Batteries** Batteries used in Phantom and Transmitter are very susceptible to cold weather flying (below freezing). Expect half capacity if battery cools to 10F. Batteries should be kept warm in an insulated box if possible. **Electronics** The electronics do not care about cold, however, once the Phantom and transmitter have become frozen, condensation may form on the electronics when brought into a warm room. In this case, do not apply power until condensation has evaporated.**Propellers**

The props that come standard on the Phantom 3 become very brittle in cold weather and may snap off even with light contact with the ground. **Fingers** Fingers quickly become num b in cold weather and control sensitivity fads with numbness. 

## Section **6 -**  **Emergencies** In - llight emergencies, as with any emergency is the least practiced and least experiences situation that you will encounter when flying. Wh ile many emergencies are not planned, proper maintenance and calibration will greatly reduce the chances of an emergency situation occurring. Also, knowing the aircraft limits and your own, can help you avoid situations that may lead to an emergency situation. Routine habits formed by following "Best Practices" for flying operations will create a mindset that the worst case scenario could happen on any flight and lead to a thought process of emergency "what if's". Thorough checklists help preparedness **Simulator practice** Since it would be a very expensive and risky operation to practice "real" emergencies, simulators fill the gap. All major airlines and the military use simulators extensively to prepare pilots for emergency situations. Use the Phantom simulator to constantly practice manual flying for those times when you are forced to. **What If's**

 Wh at should Coming Home Alt be set at  Wh at is I lose sight of the aircraft  Wh at if

it fly's away  Wh at is a "real" aircraft appears  Wh at If, W hat If, Wh at If..... **Rescue maneuvers!** A important rescue maneuver is to practice fast yaw into the nose out position where situational awareness is easiest to acquire. Note: Make a relatively slow descents if coming straight down, the prop wash disturbs the gyros and altimeter.

 Consider a locator beacon installation

## Section 7

– Photography

Aerial Photography Flying for aerial photography poses several unusual challenges. Compared to normal or aerobatic RC flying you are usually much more restricted in the space you have to take off and land fro m, you fly closer to people, property, and all sorts of obstacles, and you fly (much) higher than you do for normal or aerobatic RC flying. In addition you if you fly alone you will also have to control the camera. And for video flying you want your fli ght to be fluent so that the resultant movie requires limited editing. DO NOT do any aerial photography or aerial video flying until you are confident that you can properly control the Phantomunder the conditions you will need to fly in. **Camera gimbals** As with any muti - rotor aircraft, there are inherent vibrations due to structural design, motor imperfections, and unbalanced propellers. Wi th proper attention much of the vibration can be greatly reduces, but it impossible to eliminate all vibration. This is were a quality camera mount that has good vibration damping design comes in. **Cameras** Aerial photography has always demanded very high resolution cameras because of the altitude required for safe flight and FAA regulations. One of the great advantage s of the Phantom is that is can fly at a much lower altitude and obtain the same, quality images and often times even better. Military drone operations use micro cameras with outstanding success. Extend the basic flying practice with the following mane uvers in an open field: **Exercise A P1.**  Practice flying up to 5 - 10 meters, and then hover. Practice yawing 360 degrees in steps of about 15 degrees. Press the shutter control between each step of the yaw. After doing a full turn practice tilting the camera mount down about 15 degrees and doing another step -wise 360 - degree yaw. Do this in both directions while maintaining a stable hover. **Exercise A P2.**  Once you are confident that you can control the Phantom at this altitude, go up to about 20 meters and repe at the exercise. Note that from about 20 meters and up the altitude hold function can be used quite well to help stabilize the altitude. However you will still have to control nick, roll and yaw. Do not fly any significant distances horizontally until your are confident in hovering at larger altitudes. Only increase your altitude in a step -wise fashion after you are confident at a current altitude. **Exercise A P3.**  The maximum altitude your copter can fly under visual control is the altitude at which you can still sufficiently see the position of the MKPhantom to allow you to properly control the hover. This will vary based on weather, eyesight of the pilot, and experience. For most people it will probably be between 50 and 75 meters. That may not seem like mu ch, but remember that a 20 - story building is quadcopter. usually about 60meters so you can still take good AP pictures of even such a high buildingPhantom. You

can carefully test this envelope in an open field away from people and houses. Never try to extend this envelope beyond your known capabilities while doing an actual RC AP flight. **Exercise A P4.**  Once you can confidently hover at altitude, practice flying a virtual square of about 50 meters in each direction at the same altitudes, starting at about 10 meters and then working your way up. This is an important maneuver to master as you usually want to take your pictures from different angles. **Exercise A P5.**  For aerial video flying after having mastered the above exercises draw up a clear flight plan in which you determine a flight path and direction of view of the Phantom at each point in its path. Start easy with a square or circle at about 10 meters with a gradual ascent (either vertical or along a slope) yawing the MKPhantom if needed to keep the nos e (camera) pointed at the intended target(s). Gradually increase the complexity (e.g. with hover points where you do a particular yaw, tilting of the camera mount, increasing the altitude, etc). Also practice lower altitude flights along curving paths as for AV you may also be following e.g. speedboats or go - carts from altitudes of just 1 - 3 meters. **Exercise A P6**  . Gradually allow yourself to fly in increasing wind conditions. Although you preferably want only light winds. Once you have mastered the above, find a quiet park or field with some obstacles of different height (e.g. some spread out trees) to add complexity. Try to stay well clear of the trees. Remember that they are alive and always trying to grab your Phantom out of the sky. But think of the tree s as houses, obstacles, and targets, and use them to gradually increase the complexity of you flying conditions. Note down an outline of your flight plan before every flight, or describe it after a flight. It may we ll be that you want to make a very simil ar flight at another time at the same site to show changes over time. The closer you can copy your previous flight the better the results will be. Over time it is very likely that you will progress to flying in more densely populated areas. As indicated a bove, be obsessively compulsive about the quality and condition of your aircraft and RC system. Do not compromise on safety.
