# ROUTINE PRE- FLIGHT INSPECTION

17 

# WHAT SHOULD I INSPECT? Landing gear: If you operate a UAV with retractable landing gear, ensure the gear components, and especially, screws attaching it to 

### the frame of the UAV are not loose and servos/motors are functional. . 

### Motors: Inspect motor mount screws for tightness. With your hand, grasp each motor and check for strong attachment to the motor mount. If the motor “wobbles”, inspect the four inner screws under the motor mount. Motor replacement is advised if significant vibration is observed, and steps above are not remedial. 

### Propellers: Improper propeller mounting could result in motor failure due to overheating, as well as decrease in performance and efficiency. Whether you are using self-tightening propeller mounts, or directly mount the prop onto the motor, apply significant torque to the mounting screws. 

### Battery Plates: Ensure the battery plates’ columns are torqued fully, and the carbon fiber plate is snug. When using Velcro straps over the plate to secure a battery, tighten just enough without bending the plates on either edge. 

### GPS & IMU Make sure arrows point directly forward. Insure GPS and Compass are properly calibrated.

# PRE- FLIGHT CHECKLIST

# SAFETY PROTOCOL: Preflight

19



### ✓ Check batteries with voltmeter to insure fully charged and ready for use. 

### ✓ Inspect batteries for damage or defects that may affect proper operation. 

### ✓ Inspect propellers are mounted correctly. 

### ✓ Inspect propellers for cracks, chips or damage that may result in sudden loss of propulsion or uncontrolled flight. 

### ✓ Inspect dampening absorbers are in good condition; not broken or worn. 

### ✓ Camera lens cap has been removed. 

### ✓ Micro SD card has been inserted. 

### ✓ Gimbal is functioning properly. 

### ✓ Check weather forecast for wind advisory or other conditions that may adversely impact flight. 

### ✓ Check predetermined flight area forTFR, restrictions, etc. 

### ✓ Check for N OT

AMs for flight area. 

### ✓ Contact respective airport towers to advise of estimated time of flight, estimated flight duration, flight location, estimated maximum altitude of flight and any other pertinent information. 

### ✓ If required, inform local FAA FSDO 

### ✓ Inspect flight area for:  vicinity of medical helipads/heliports 

###  vicinity of light poles  vicinity of trees  flocks of birds that may cause interference and potential flight impact  vicinity of any elevated obstructions that may pose potential flight hazard  vicinity of roadways with moderate to heavy traffic that can be d istracted  public gatherings that may attract viewers  optimal point of control for best sight of sUAS while in flight

# SAFETY PROTOCOL: Flight

 Takeoff and land from same predetermined safe area.  Remain alert to birds, aircraft, curious public and approaching vehicles. 

#  PIC or Visual Observer will avoid any distractions during flight.  Restrict flight to minimal altitude sufficient to acquire needed results. 

#  Remain prepared for emergency landing at all times.  Pay attention to flight time and battery life percentage.  Land sUAS and shut down propulsion immediately following landing.

20

# SAFETY PROTOCOL: Post- Flight

 Disconnect battery( ies) to prevent accidental activation of propulsion system . 

#  Inspect sUAS for physical irregularities/component malfunction .  Secure sUAS in a safe location .  Log your flight time, sUAS performance and other 

# pertinent information  Remove all warning signs from public access areas .

21

# SAFETY PROTOCOL: Emergencies Immediately land the sUAS at the safest and closest

ground location if

:

 the PIC and/or the Visual observer is being distracted 

# from focusing on the flight and safety.  a manned aircraft is heard or seen in vicinity of the sUAS .  a sudden change in weather (thunderstorms and/or convective activity) .  birds entering the proximity of the flight .  any sudden unsafe event that can cause collision, distraction or interruption of control .

For more information on ESC calibration, battery monitoring, failsafes, mode descriptions, and more, visit ardupilot.com . Do not operate your vehicle without a complete understanding of the online instructions.Operating a powered vehicle of any kind can be a lot of fun, but it carries certain inherent risks. Regulations governing the use of powered vehicles, including aircraft, vary from locale to locale, even within the same country or district. It is your responsibility to ensure that you understand and comply with all local laws and regulations. Safety basics:

• Never operate the vehicle or software in a way that could be dangerous to you, other people, or property. • Always keep propeller arcs free of objects and body parts while the vehicle is live. • Keep in mind that software and hardware failures happen. Although we design our products to minimize

such issues, you should always operate with the understanding that a failure could occur at any time and without warning. Accordingly, you should take the appropriate precautions to minimize danger in case of product failure. • Never use the software or hardware for manned vehicles. • Always operate within local laws and regulations. • Do not operate the aircraft if you are under the age of 18. Additional safety information:

• Be sure to maintain safe distances between people and your aircraft. • Never operate your aircraft if your ability to do so with the utmost attention to safety is impaired in any

way. Do not operate your aircraft while tired, under the influence of drugs or alcohol, or otherwise unable to operate it with the highest attention to safety. • Environment conditions can change rapidly and can make operation difficult. If this occurs, land your aircraft

and discontinue use immediately. Do not operate your aircraft if operating conditions are not ideal. This includes, but is not limited to, rain, snow or excessive wind. • Always ensure the battery cable is disconnected from the aircraft until you are ready to fly, and ensure that

your batteries are fully charged prior to use. • Always turn on the transmitter and ensure the throttle stick is all the way down before connecting the

battery. • After landing, disarm your vehicle immediately and disconnect the battery cable. • Do not turn off the transmitter until after you have disconnected the battery. • Always remove the propellers while testing the motors. • When the battery is connected, always assume the vehicle is live and the motors are armed. • Do not attempt to fly longer than the battery’s safe capacity. • Do not operate the vehicle with excess weight attached. • Ensure that all vehicle components are well maintained before each flight. Ensure that components are

firmly attached and operating properly. • Replace any worn or damaged components before each flight. Never operate with any damaged or worn

components. • SAFETY IS THE FIRST PRIORITY. Take all precautions necessary to ensure your own safety as well as the

safety of other people and property.
