## Flight Status Indicator The Phantom 3 Professional has Front LEDs and Aircraft Status Indicators. The positions of these LEDs are shown in the figure below:

The Front LEDs show the orientation of the aircraft. The Front LEDs glow solid red when the aircraft is turned on to indicate the front (or nose) of the aircraft. The Aircraft Status Indicators communicate the system status of the flight controller. Refer to the table below for more information about the Aircraft Status Indicators: 

# Aircraft
Flight Controller The Phantom 3 Professional’s flight controller features several important upgrades, including a new flight mode. Safety modes include Failsafe and Return-to-Home. These features ensure the safe return of your aircraft if the control signal is lost. The flight controller can also save critical flight data from each flight to the on-board storage device. The new flight controller also provides increased stability and a new air braking feature. 

## Flight Mode 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, which 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 available. 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-ATTI: 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. For more information about IOC, refer to the IOC section in the Appendix.

Use the Flight Controller mode switch to change the flight mode of the aircraft, refer to the “ Flight Mode Switch” on Page 26 for more information.

## Return-to-Home (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. GPS Description

Home Point If a strong GPS signal was acquired before takeoff, the Home Point is the location from which the aircraft was launched. The GPS signal strength is indicated by the GPS icon ( ). The aircraft status indicator will blink rapidly when the home point is recorded.



## Smart RTH Use the RTH button on the remote controller (refer to “RTH button” on page 26 for more information) or tap the RTH button in the DJI GO 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.© 2015 DJI.

Low battery level warning The battery power is low. Please land the aircraft. Aircraft status indicator blinks RED slowly. Tap “Go-home” to have the aircraft return to the Home point and land automatically, or “Cancel” to resume normal flight. If no action is taken, the aircraft will automatically go home and land after 10 seconds. Remote controller will sound an alarm. Fly the aircraft back and land it as soon as possible, then stop the motors and replace the battery.

Critical Low battery level warning The aircraft must land immediately. Aircraft status indicator blinks RED quickly. The DJI GO app display will flash red and the aircraft will start to descend. The remote controller will sound an alarm. Allow the aircraft to descend and land automatically.

Estimated remaining flight time Estimated remaining flight based on current battery level. N/A N/A N/A 

## Low Battery RTH The low battery level failsafe is triggered 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 GO 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 user can still use the remote controller to alter the aircraft’s orientation during the landing process.


### The Battery Level Indicator is displayed in the DJI GO app, and is described below:

Aircraft cannot return to the Home Point when GPS signal is weak ( [ ] displays grey) or unavailable. Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 20 meters (65 feet) radius of the Home Point. Aircraft will stop ascending and immediately return to the Home Point if you move the throttle stick if the aircraft reaches 20 meters (65 feet) altitudes or beyond during Failsafe. The aircraft cannot avoid obstruction during the Failsafe RTH, therefore, it is important to set an suitable Failsafe altitude before each flight. Launch the DJI GO app and enter “Camera” and select “MODE > Advanced Settings > Failsafe mode” to set the Failsafe altitude. User cannot control the aircraft while the aircraft is ascending to its failsafe altitude. However, user can press RTH button once to exit ascending and regain control.

## Vision Positioning System
The DJI Vision Positioning System uses ultrasound and image data to help the aircraft maintain its current position. With the help of Vision Positioning, your Phantom 3 Professional 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.

[1] [2] 20 m 20 m
H If the aircraft is flying under 20 meters (65 feet) and Failsafe (including Smart RTH, Lower Battery RTH ) is triggered, the aircraft will first automatically ascend to 20 meters (65 feet) from the current altitude. You can only cancel the ascending by exiting the Failsafe. Refer to “ RTH Button ” on page 26 for more information on how to exit the Failsafe and regain the control of the remote controller.

20 m 20 m
H Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 20 meters (65 feet) radius of the Home Point. Aircraft will stop ascending and immediately return to the Home Point if you move the throttle stick if the aircraft reaches 20 meters (65 feet) altitudes or beyond during Failsafe.

20米 20米
H Aircraft cannot return to the Home Point when GPS signal is weak ( [ ] displays grey) or unavailable.

20米 20米
H if you move the throttle stick after the aircraft rises above 65 feet (20m) but below the pre-set Failsafe RTH altitude, the aircraft will stop ascending and immediately return to the Home Point.

Using Vision Positioning Vision Positioning is activated automatically when the Phantom 3 Professional 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 Professional can hover precisely even without GPS.

### 16 © 2015 DJI. All Rights Reserved. The performance of your Vision Positioning System is affected by the surface over which 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 patterns 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. 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 th e aircraft is flying 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 sounds that are only audible to some animals. Follow the steps below to use Vision Positioning: 1. Toggle the flight mode switch to P-mode. 2. Place the aircraft on a flat surface. Note that the Vision Positioning system cannot

work properly on surfaces without clear pattern variations. 3. Turn on the aircraft. The aircraft status indicator will flash green two times, which

indicates the Vision Positioning system is ready. Gently push the throttle up to lift off and the aircraft will hover in place.



## Flight Recorder Flight data is automatically recorded to the internal storage of the aircraft. This includes flight telemetry, aircraft status information, and other parameters. To access these data, connect the aircraft to the PC through the Micro-USB port and launch the DJI GO app.© 2015 DJI. All Rights Reserved.
