D’Avion LLC UAS Flight Operations and Training Manual



## D’Avion LLC UAS Flight Operations and Training Manual

Introduction

This manual describes the flight operations of D’Avion LLC . This includes roles and responsibilities, mission phases and emergenc y procedures. The aim is to document everything that is needed to be done during a mission, so it can act as a reference point for team members.

Roles and Responsibilities

PIC

● Flying the UAS in Manual or Auto Pilot mode. This may include takeoff, landing or during

em ergency procedures (when the UAS is circling Airfield Home and needs to be landed)

● Assembling the UAS ( Cameras, batteries, sensors ) and acting as a point of contact on the flight line during preflight checks

● The PIC and the SO will be the only team members on the flight line

SO

● Assists the PIC with their tasks.

● If the PIC is unavailable, performs their tasks (if SO has proper credentials)

● The PIC and the Backup PIC and SO will be the only team members on the flight line

● Acts as communications l ink between pilot and Ground Station

Airframe and Navigation (PIC )

● Monitors the state of the UAS

- altitude, speed, roll, pitch, etc.

● Monitors the UAS ’s progress through the mission waypoints

● Ensures that the correct waypoints have been loaded

● During emerg ency situations, ensures the UAS diverts to the correct waypoint/loiter

● Monitors the time, ensuring the UAS will finish the search pattern within the allocated time limit.

● Monitors position of UAS relative to the geofence, particularly in Manual mode

Camer a and Payload Control ( PIC )

● Confirms the Camera is capturing correcting

● Monitors the camera capture and image processing

● Makes the call as to where SO is located , in consultation with other UAS people

Safety and Procedures ( PIC )

● Monitors other teams membe rs to ensure a safe environment

● Ensures team is following the Procedures and Operations Manual

● Provides antenna pointing directions33 Pre

- startup checks (PIC)

● Verify

○ All servos and flight control surfaces responsive

○ Software running

○ RC radio link working

● Co nfirm GPS Lock

● Co nfirm compass enabled, COMPASS_USE=1

● Confirm Altitude lock

● Ensure flight mode MANUAL and/or auto pilot

● Airspeed calibration and check

● Receiver failsafe check

● Check barometric pressure sensor calibration

Post

- startup Checks

● Engine running nominally

● Ensure flight mode MANUAL /Auto pilot as appropriate

● Double check barometric sensor is showing 0m altitude

● Ensures current waypoint set to 0

Flight Phases

Takeoff and cru ise to search area

● Takeoff may be automatic or manual, depending on weather conditions and how confident we are feeling.

○ For automatic takeoff, the pilot switches to AUTO via left switch and then right switch ( depending on UAS type ). The UAV then takes off

○ For manual takeoff, allow the pilot to set to Manual mode . After takeoff an d when the UAS is at least 30m off the ground, switch to auto pilot mode as appropriate

. On c e the UAS has stable flight, the pilot switches to AUTO.

● The UAS shoul d reach a target altitude of 399 AGL (or less) in approx 25 seconds.

● Once the UAS is in stable AUTO flight, the GCS will disable any stick mixing ( prop control)

● Before the UAS is outside RC control range, the pilot will switch off the RC transmitter for UAS to return to base launch site or will push RTH (Return to Home) button.

Return to Take Off P oint (PIC)

● Always keep an eye on t he UAS as it tracks to airfield /take off point , etc

. Landing (PIC )

● Landing may be automatic or manual, depending on weather conditions.

● By defau lt it will automatically land

○ In automated mode, the PIC must keep a careful e ye on t he speed and altitude of the UAS.

○ The PIC will ensure the appropriate camera s are turned off once photography/video mission is complete.

○ If, at any point during the landing, if the PIC is not confide nt in the auto landing the POC will manually tak e over and land th e UAV.

○ During a manual landing, the VO will call out the air speed and altitude for the PIC.34 Emergency Procedures

Loss of Datalink

● Occurs if the both datalinks are lost (no heartbeat) for more than 10 seconds

○ If combined with a loss of GPS

, the UAS must terminate

○ The RC link fai ls during manual flight, the UAS must terminate

● The UAS will automatically fly to the preset h old waypoint or return to take off point.

Loss of GPS

● If the GPS reports a loss of lock, the UAS will return to home or pr eset waypoint.

Loss of engine power

● If the UAS 's airspeed and altitude drop, the engine has most likely stopped

● The PIC will do w ay p oint set for RTH or safe place to land if not enough distance above AGL.

UAS or Computer Software failure

● If the main UAS l aptop AND the both radio links fai l for more than 10 seconds, the UAS will RTH mode or to the preset waypoint.

The Waypoint ID’s are as follows: (may have more waypoints or less depending on mission of UAS).
