CEMC Electric Utilities Unmanned Aerial System Operations Manual 

Part A: INTRODUCTION

The following procedures are intended to promote the safe, efficient, and lawful operation of the 

Cumberland Electric Membership Corporation (CEMC) unmanned aerial system (UAS). 

Section 1: Introductory Statement 

It is the mission of the personnel of CEMC who are trained in the use of UAS, to use this resource to 

enhance the lives and property of the citizens of Tennessee in a constitutionally and legally sound 

manner. Use of an aerial system can be utilized in circumstances which would further the public interest 

in the safe and reliable delivery of electricity to customers, as well as allow the decreased need of 

bucket trucks or conventional aircraft. This would increase the safety and efficiency of Utility workers 

who would now be able to conduct inspections without being in close proximity to high-voltage 

equipment or subject to the height related hazards of the bucket trucks and conventional aircraft. 

The need for the use of UAS’s is growing at an incredible rate and the implementation of commercial 

rules and regulations is desperately needed. UAS’s can be used for a variety of purposes. CEMC proposes 

to use UAS’s to streamline transmission/distribution line repair, troubleshooting, etc. Today, CEMC uses 

comparatively hazardous conventional rotary aircraft or foot patrols for these inspections. These 

inspections can also be in areas of downed power lines. The use of UAS’s allow tasks such as these to be 

accomplished from the air in an efficient, effective, and safe manner. UAS's also provide a measure of 

safety to the general public that is not available with traditional helicopter use for inspection of 

transmission and distribution lines. 

It shall be the intent of every UAS operator to not invade a person’s privacy when operating the UAS. 

When operating the UAS, CEMC will abide by all FAA Regulations for flight, receive the proper 

authorization for flight, and follow all preflight and flight procedures listed below.

Compass - Guidelines: 

1. Ensure the compass is calibrated before every flight. Failure to calibrate may lead to a poor 

flight performance or even failure. 

2. DO NOT calibrate the compass when there is a chance of strong magnetic interference. This 

includes areas where there are massive metal objects, parking structures, steel reinforcements 

underground, or under bridges. 

3. DO NOT carry ferromagnetic materials with you during calibration, such as keys or mobile 

phones. 

4. The compass should always be recalibrated when moving from indoor to outdoor spaces. 

5. If the rear LED shows a solid RED light, the compass calibration has failed. The compass must be 

recalibrated. 

6. After successful calibration, the compass may become abnormal when you put the aircraft on 

the ground. This is because of magnetic interference that may be underground. Move the 

aircraft to another location and try again.

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

Parameter Settings: 

The Inspire-1 has a built in flight control system to make operations as safe as possible. It is good 

practice to remove all propellers before switching it on for calibration or changing other parameter 

settings. 

Section 7: Area of Operation 

All unmanned aerial systems (UAS) operators must abide by all regulations from the Federal Aviation 

Administration (FAA) and any other applicable airspace regulations in their area. In order to increase 

flight safety and prevent accidental flights in restricted areas, DJI has a "No Fly Zone" feature to help 

utilize DJI products safely. These zones include airports and other areas where flying may pose an 

unnecessary risk (such as national borders, sensitive institutions, etc.). Around large airports (DJI 

category A airports) there is a no fly zone with a 5 NM (8 km) radius. Around small airports (DJI category 

B airports) there is a no fly zone with a 0.6 NM (km) radius. 

Areas of operation will include property owned by CEMC and in areas that are utility right-of-way. 

Submitted with this document are the KMZ files of the operating areas. These UAS routes follow 

transmission and distribution lines controlled by CEMC. 

The areas of operation for UAS’s will have an altitude limitation of 200 feet AGL. 

Section 8: Operating Limitations and Conditions Operational Control 

The following limitations are set forth per the manufacturer's instructions. Any additional flight 

parameters will be addressed in the operating procedures section. 

8.1: Flight Environmental Requirements: 

1. Do not use the aircraft in severe weather conditions. This includes but is not limited to: wind 

speeds exceeding 10 m/s, snow, rain, and smog. 

2. Only fly in open areas. Tall buildings and steel structures may affect the accuracy of the onboard compass and GPS signal. 

3. Avoid from obstacles, crowds, high voltage power lines, trees or bodies of water. 

4. Minimize electromagnetic interference by not flying in area with high levels of 

electromagnetism, including mobile phone base stations or radio transmission towers. 

5. Aircraft and battery performance is subject to environment factors such as air density and 

temperature. Be careful when flying 14700 feet (4500 meters) or more above sea level as 

battery and aircraft performance may be reduced. 

6. The Inspire 1 cannot operate within the polar areas in "P" mode. 

8.2: Flight Limits and Flight Restriction Area 

All UAS PIC are to abide by all regulations from such organizations as the International Civil Aviation 

Organization (ICAO), FAA, as well as the regulations set forth by CEMC. 

For safety reasons the flight limits function is enabled by default to help users use this product safely 

and legally. The flight limits function includes height limits, distance limits, and No Fly Zones. 

For operations in "P" mode, height, distance limits, and No Fly Zones work together to manage flight. In 

"A" mode, only height limits work and flights cannot go higher than 120 meters.

No-Fly Zones 

All No Fly Zones are listed on the DJI website at www.dji.com/no-fly. These No Fly Zones are divided into 

Airport and Restricted Areas. Airports include major airports and flying fields where manned aircraft 

operate at low altitudes. Restricted Areas include borders between countries or sensitive sites. 

Airports: 

1. Airport No-Fly Zones are comprised of Takeoff Restricted Zones and Restricted-Altitude Zones. 

Each zone features various sized circles. 

2. R1 depends on the size and shape of the airport. It is an area around the airport that is a Takeoff 

Restricted Zone. In side this circle take-off and flight is prevented. 

3. R1 + 1 mile around the airport, flight altitude is limited on a 15° incline. This begins at 65 feet (20 

meters) from the edge of the airport, radiating outward. The flight altitude is limited to 1640 

feet at R1 + 1 mile. 

4. When the UAS is within 320 feet (100 meters) of a No Fly Zone, a warning message will appear 

in the DJI Pilot app. 

Figure 1: Airport No Fly Zone 
17 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

Restricted Areas: 

1. Restricted Areas do not have a flight altitude restriction. 

2. R around the designated Restricted Area is a Take-off Restricted area. Aircraft cannot takeoff 

within this zone. The value of R varies depending on the definition of the Restricted Area. 

3. A "warning zone" has been set around each Restricted Area. When the aircraft is within 0.6 

miles (1 km) of this zone, a warning message will appear in the DJI Pilot app.

is not limited to: mobile base stations and broadcasting towers. Failing to do so may 

compromise the transmission quality of this product, cause remote controller and video 

transmission errors may affect flight orientation and location accuracy. 

 P mode is unavailable in polar zones. Users can use ATTI mode instead. 

 Do not fly the aircraft within no fly zones specified by local laws and regulations. 

Range Limits: 

4. Fuel 

 Fuel capacity is a primary limiting factor. 

 Flying into the wind will use more battery power to travel the same ground distance. 

Higher air speeds will be required to penetrate the wind which used more battery 

power. Take this into account when flying a mission. 

 Where possible, fly upwind at the start of a mission and downwind at the end to avoid 

depleting the battery before returning to base. Have alternative landing sites available 

in case of emergency landing. 

Section 9: Supervision of UAS Operations

 Check the battery pins and rub them clean with an eraser if any residue is observed. This will 

help to ensure a more reliable connection. 

 Check the metal battery power connectors for damage. If the connectors appear burnt, try 

to clear them. This can be done by inserting a piece of sandpaper (1 mm thick) into the 

connectors to polish the metal. 

 Check the contact pins in the battery compartment to ensure that the pins are clear. They 

should be able to establish easy contact with the battery connectors and should not be 

bent. 

 Check the electrodes on the battery. If they appear burnt, polish them with sandpaper. If 

there is serious erosion, send the battery in for repairs. 

 Check the plastic components of the battery bracket to see it is in good condition and that 

all screws are secure. This prevents the battery from becoming loose during flight. 

 Check the power cables between the arms and the center plate, if the cables are worn, 

contact DJI to arrange repairs. 

 For long term storage, please refer to the "Intelligent Flight Battery Safety Guidelines" and 

check the battery once a month to prevent the battery cell from being damaged. 

 Run the DJI Pilot App to confirm that all battery cells are at similar voltage levels and stay at 

the same level when the battery is fully charged. If all cells maintain voltage levels above 

3.7V but any cell is 0.2V higher or lower than the others, contact DJI for analysis. You can 

also check the battery cell warning history. If any warnings are reported, contact DJI. 

3. Transformation System 

 Check the servomotor cables for wear. Also confirm that the connection points are still in 

good condition. 

 Check the lead screws and contact DJI Support to arrange repairs if any bending or damage 

is discovered. Clean the lead screws with WD-40 spray if they show signs of rust. 

 Listen to the servomotors during the transformation, if there is abnormal noise, it may 

indicate that the servomotors worn. 

 After the landing gear rises, check the lead screws and bearings. If any dirt or dust is found, 

clean and grease the bearings. 

 Check the lead screws. If there are any scratches, dents, or plastic particles underneath 

them, contact DJI Support to arrange repairs. 

4. Checking the Aircraft 

 Confirm that all the screws are still adequately tightened. 

 Check the aircraft for breaks or damage. If there is any reason to believe that detectable 

damage might affect flight safety, consult with DJI support.

 Ensure that there are no obstacles on or around the GPS module or around the antennas on 

the landing gear. Remove any obstacles (such as tape with conductive material) that might 

affect or block the signal. 

 Check that the right and left landing gear rest at the same tilt angle. 

5. Checking the Motors 

 Check the rotors to confirm that they have not become loose. 

 Detach the propellers and start the motors. Listen carefully. If there is any abnormal noise, 

please replace the motors. This may be a sign that the bearings have been worn out. 

 Detach the propellers and start the motors. Carefully examine the edge of the rotor and 

confirm that the shaft is perfectly centered on the motor. Check for any abnormal or 

excessive vibration. If any problems are detected, contact DJI Support to order replacement 

motors. 

 Check for deformities by confirming that the gap between the motor and the motor base is 

even. If not contact DJI Support to order replacement motors 

 Ensure that the screws used to secure the motor base are tight and the plastic components 

around the motors are in good condition. If not please tighten the screws and contact DJI to 

repair any broken plastic components. 

6. Checking the Propellers 

 Check the propellers. If there is any bending, breakage or cracking on a propeller, do not use 

it. 

 Attach the propeller to the motor, turn on the aircraft, and place it on the ground. Stand 1 

meter away from the aircraft and observe the rotating propellers. If you can see two distinct 

propeller outline layers, when looking at a spinning propeller from the side, this propeller is 

damaged and should not be used. 

7. Checking the IMU 

 Open DJI Pilot app to check the condition of the IMU and perform an advanced IMU 

calibration. Please place the aircraft in a cool environment and on a flat, stable surface (if 

the landing gear is damaged, support the aircraft with four objects of equal height). Do not 

touch the craft during the calibration. 

 Turn off the aircraft and listen for any abnormal noise or vibration from the fan located on 

the front of the aircraft. If any irregularity is detected, replace the fan. 

8. Checking the Control and Video Transmission System 

 Check the four antennas on the landing gear to ensure that they are secure. Also check for 

any bending or damage. 

 Check the antennas for the remote controller for damage. 

 Check the neck strap for damage or wear, replace if necessary. 

9. Checking the Gimbal and Camera 

 The quick-mount connector for the camera is a particularly vulnerable component. If the 

gimbal fails to initialize when turned on, fails to work after initialization, or fails to transmit 
28 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

video to the app (while OSD data is displayed), the quick-mount connector may be worn. In 

this case, replace the rubber amt, circuit board, and/or connector on the gimbal quickmount. 

 Check the metal contacts on the quick mount board, if any contact is bent, replace the 

quick-mount connector. 

 Check the contact pins on the quick-mount connector board, if there is any dirt, rub it clean 

with an eraser. If any contact pins are worn out if should be replaced. 

 Confirm that the gimbal is able to properly stabilize itself. If its stabilizing performance 

deteriorates, contact DJI to arrange repairs. 

 Listen for any abnormal noise from the fan when the gimbal is turned on. This may indicate 

unusual vibration and the fan should be replaced. 

10. Checking the Vision Positioning System 

 Check the lends of the camera. If any dirt or residue is detected, gently clean the lens. 

 Check for and remove objects that might block the sensors. 

 Ensure that the Vision Positioning System is securely installed on the aircraft. 

 Detach the propellers and turn on the aircraft. Hold the aircraft 1-2 meters above a surface 

with rich patterns, under good lighting conditions. Change the Flight Mode switch to P Mode 

on the controller and check the DJI Pilot app. If the app displays an altitude value and 

indicates that P-OPTI mode is active, the Vision Position System should function normally.

PREVENTATIVE MAINTENANCE 

11. Annual Inspection

information to make themselves familiar with the weather situation existing throughout the 

area of deployment. The operator shall utilize FAA approved weather resources to obtain the 

latest and most current weather conditions. 

 An anemometer should be utilized in order to better estimate the wind speed and determine if 

it is within the capabilities of the airframe being flown. 

 Operators/Observers should use the Beaufort Scale when making deployment decisions in 

regards to wind conditions. This scale can be located in the manufacturer's user manual. 

 The weather conditions reported for the operation shall be recorded in the flight log. 

 The operator shall ensure that the flight will occur within FAA VFR weather requirements. 

2.7: Refueling 

The DJI Inspire-1's fuel supply is through a battery. Flights shall be terminated at 25% battery power 

reserve. The total maximum operation flight time shall be 60 minutes or less. 

The following factors shall be considered prior to flight regarding fuel/refueling: 
31 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

 Fuel capacity is a primary limiting factor. The capacity of the fuel for a UAS shall be considered 

prior to any and all flights. 

 Flying into the wind will use more battery power to travel the same ground distance. Higher air 

speeds will be required to penetrate the wind which used more battery power. Take this into 

account when flying a mission. 

 Where possible, fly upwind at the start of a mission and downwind at the end to avoid depleting 

the battery before returning to base. Have alternative landing sites available in case of 

emergency landing. 

2.8: Loading of Equipment 

The only type of equipment that shall be loaded onto the UAS is the camera/optical element. This shall 

be loaded as instructed per the Manufacturer's instructions.

***It is important to note that the compass should be calibrated prior to every flight, in every new flight 

location. The compass is very sensitive to electromagnetic interference, which can cause abnormal 
34 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

compass data leading to poor flight performance or even failure. Regular calibration is required to 

optimum performance. 

Compass Calibration Precautions: 

 DO NOT calibrate your compass where there is a chance of strong magnetic interference, such 

as magnetite, parking structures, and steel reinforcements underground. 

 DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular 

phones.

 DO NOT calibrate beside massive metal objects. 

Calibration Procedures 

Chose an open space to perform the following procedures: 

 Ensure that the compass is calibrated. If you did not calibrate the compass as part of your preflight preparations, or it you have moved to a new location since the last calibration, tap Aircraft 

Status Indicator bar in the app and select "Calibrate", then follow the on-screen instructions. 

 Hold and rotate the aircraft horizontally 360°. The aircraft Status Indicator will display a solid 

green light. 

 Hold the aircraft vertically with the nose pointing downward. Rotate the aircraft 360° around 

the center axis. Recalibrate the compass if the Aircraft Status Indicator shows solid RED. 

*If the Aircraft Status Indicator blinks RED and YELLOW after the calibration, move your aircraft to a 

different location to carry out compass calibration. 

**Calibrate the compass before each flight. Launch DJI Pilot App, follow the on-screen instruction to 

calibrate the compass. 

Recalibration of Compass is Necessary: 

 When compass data is abnormal and the Aircraft Status Indicator is blinking RED and YELLOW. 

 When flying a new location or a location that is different from the previous flight. 

 When the mechanical structure of the Inspire-1 has changed (i.e. changed mounting position of 

the compass). 

 When severe drifting occurs in flight (i.e. the Inspire-1 does not fly in straight lines). 

2.12: P Mode 

In P Mode, the DJI Inspire-1 has a strong GPS signal and can use the Vision Positioning System. This 

allows the aircraft to hover accurately in position indoors and out. If outside, P Mode also means that a 

Home Point has been locked so that it can Return to Home if the control signal is lost. 

If this mode is not enabled, toggle the Flight Mode Switch to the P position to enable. The Flight Mode 

Switch is locked in P Mode by default. 

There are three states in P Mode: 
35 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

1. P-GPS: GPS works best when outside in wide open areas. The Inspire-1 uses GPS to hover in 

place while the GPS signal is strong. 

2. P-OPTI: If GPS is not available, the aircraft can use the Vision Positioning System to hover 

accurately. 

3. P-ATTI: Both GPS and Vision Positioning System are unavailable. The aircraft is using only its 

barometer for positioning; only altitude is controlled. 

***Vision Positioning System may not work properly when the Inspire-1 is flying over water, over 

surfaces without a clear pattern or in low light environment.

3.4: Return to Home (RTH) 

The Return to Home (RTH) brings the aircraft back to the last recorded Home Point. There are three 

cases that will trigger the RTH procedure: Smart RTH, Low Battery RTH, and Failsafe RTH. 

Smart RTH: 

Using the RTH button on the remote controller or the RTH button in the DJI Pilot App when GPS signal is 

available to enable smart RTH. The aircraft will return to the latest recorded Home Point. The operator 

may retain control of the aircraft's orientation to avoid collision during the Smart RTH. Press the Smart 

RTH button once to start the process. Press the Smart RTH button again to exit Smart RTH and regain full 

control. 

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 these warning are shown. The DJI Pilot App will advise the operator to return the 

aircraft to the Home Point when the battery warning is triggered. The aircraft will automatically return 

to the Home Point if no action is taken after a 10 second countdown. Operators may cancel the RTH by 

pressing once on the RTH button. The thresholds for these warnings are automatically determined 

based on the current aircraft altitude and its distance from the Home Point. 

The aircraft will land automatically if the current battery level can only support the aircraft to land to the 

ground from the current altitude. Operators may use the remote controller to control the aircraft's 

orientation during the landing process.

4.2: Additional Guidelines 

The following section describes additional guidelines as related to features associated with the DJI 

Inspire-1. 

1. Dynamic Home Point 

The Dynamic Home Point is useful in situations during motion of the operator when the Home Point is 

different from the takeoff point. To ensure proper function of the Dynamic Home Point, it is important 

that the space above the GPS module is not obstructed during use. 

There are two options for the Dynamic Home Point. 

 Set the aircraft current coordinates as the new Home Point; or 

 Set the remote controller's coordinates as the new Home Point. 

To set up the Dynamic Home Point, please refer to the instructions listed on page 15 of the User Manual 

issued by the manufacturer. 

2. Vision Positioning System 

The DJI Vision Positioning System uses ultrasonic and image data to help the aircraft identify its current 

position. The Vision Positioning System assists the Inspire-1 to hover in place more precisely, fly indoors, 

or in other environments where there is no GPS signal available. The main components are located on 

the bottom of the Inspire-1 and includes two sonar sensors and one monocular camera. 

The Vision Positioning System is automatically activated when the Inspire-1 is powered on. No additional 

manual action is required. 

The performance of the Vision Positioning System is directly related to the surface the Inspire-1 is flying 

over. The ultrasonic waves may not be able to accurately measure the distance over sound absorbing 

materials and the camera may not function correctly in suboptimal environments. The aircraft will 

switch from 'P' mode to 'A' mode automatically if both GPS and Vision Positioning System are not 

available. Be cautious when flying: 

 Over monochromatic surfaces (i.e. pure black, pure white, pure red, pure green, etc.) 

 Over a highly reflective surface 

 At high speeds (over 8 m/s at 2 meters or over 4 m/s at 1 meter) 

 Over water or transparent surfaces 

 Over moving surfaces or objects 

 In an area where lighting changes frequently or drastically 

 Over extremely dark (lux < 10) or bright (lux > 10,000) surfaces 

 Over surfaces that can absorb sound waves such as thick carpet 

 Over surfaces without clear patterns or texture 

 Over surfaces with identical repeating patterns or textures such as tiles with the same 

design 

 Over inclined surfaces that will deflect sound waves away from the aircraft 

In the event of the loss of remote controller signal, the aircraft will hover for 8 seconds and then autoland if it is in 'P' mode. 

Additional Guidelines: 

 Keep the sensors clean at all times. Dirt or other debris may adversely affect the 

effectiveness of the sensors.

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

 The effective hovering altitudes of the aircraft is from 0 to 2.5 meters. 

 The Vision Positioning System may not function properly when the aircraft is flying over 

water. 

 The Vision Positioning System may not be able to recognize pattern on the ground in low 

light conditions (< 100 lux). 

 Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning 

system is in operation. 

 The Vision Positioning System may not be able to stabilize the aircraft when flying too close 

to the ground (< 5 meters) in fast speed. 

 Keep animals away from the aircraft when the Vision Positioning System is activated. The 

sonar sensor emits a high frequency sound that is only audible to some animals. 

3. Flight Recorder 

Flight data is automatically stored in the internal storage device of the aircraft. Users can gain access to 

this data through the DJI Pilot App. This includes flight duration, orientation, distance, aircraft status 

information, speed, and other parameters. 

4.3: Warnings and Limitations 

Flight Warnings 

Failsafe and Return to Home 

 Return to Home will not work if the GPS signal is insufficient or GPS is not active. 

 Press the RTH Button on the remote controller to bring the aircraft back to Home Point 

instead of turning off the remote controller. 

 Tall buildings may adversely affect the Failsafe function. Please adjust the aircraft location, 

altitude, and speed while returning home to avoid obstacles. 

 Make sure to always fly the aircraft within the transmission range of the remote controller. 

 When updating the Home Point, do not block the GPS signal of the remote controller and 

ensure the new Home Point is correct on the live map. 

 Do not update the Home Point near tall buildings, as the GPS may be blocked and lead to an 

incorrect location being stored. 

 Only use the Failsafe and Return to Home functions in case of emergency, as they may be 

affected by the weather, the environment, or any nearby magnetic fields. 

Low Battery 

 When the Critical Battery Level Warning activates and the aircraft is descending 

automatically, you may push the throttle upwards to hover the aircraft and navigate it to a 

more appropriate location for landing. 

 When the battery warning are triggered, please bring the aircraft back to the Home Point or 

land to avoid losing power during flight. 

Vision Positioning System 

 The Vision Positioning System cannot work properly over surfaces that do not have pattern 

variations. The effective altitude for Vision Positioning System to function correctly is less 

than 2.5 meters. 

 Vision Positioning System may not function properly when the aircraft is flying over water or 

other highly reflective surfaces. 
49 | Page

CEMC Electric Utilities Unmanned Aerial System Operations Manual 

 Vision Positioning System may not be able to recognize patterns on the ground in low light 

conditions (less than 100 lux). 

 Keep pets away from the aircraft when Vision Positioning System is activated, as the sonar 

sensors emit high frequency sound that is only audible to some pets. 

 Note that Visual Positioning System may not function properly when the aircraft is flying too 

fast or too low. 

Transformation Function 

 Ensure the landing gear is lowered before landing. 

 Stay away from the aircraft when it is transforming to prevent injury. 

 DO NOT attempt to catch the aircraft, as the landing gear will lower if the Visual Positioning 

System detects an object and may cause injury. 

 Keep the aircraft arms clean, otherwise transformation may be affected. 

 Never apply lubricants to the aircraft arms. 

Other 

 If using a phone as your mobile display device, be sure to continue flying safely if you 

receive an incoming call. 

 Land as soon as possible if there is an alert shown on the DJI Pilot app. 

 Upon landing, power off the aircraft first, then switch off the remote controller. 

4.4: Accidents 

Accidents and serious incidents are required to be immediately notified. 

Written notifications are required to be submitted within 72 hours of an accident, serious incident or 

incident. The written notification should contain as much information about the accident, serious 

incident, or incident as is within the knowledge of the person at the time of submitting the notification. 

In the event that an emergency landing is necessary: 

 If alternate emergency landing zones should be chosen ahead of time. 

 Be sure that the LZ is clear of people to avoid any incidents. 

 Land in the nearest LZ which is clear of people. 

 Announce your intentions of landing as loud as necessary to alert people of the incoming 

AV. 

***Any incident, accident, or flight operation that transgresses the lateral or vertical boundaries defined 

in an issued COA shall be reported to the FAA within 24 hours.
