Study Notes
Transition Timeout
- The UAV will perform an automatic emergency landing after 30 seconds if it doesn’t complete the transition or reach 60 km/h.
- If the UAV descends below 30 meters, an immediate QLAND command should be issued.
Communication Interruptions
- A red “Comm” alert, red UAV icon, or frozen/blinking telemetry updates indicate a communication interruption and the UAV entering “Loss of Link” logic.
- Actions should include switching communication channels, increasing amplification, and verifying GDT and GCS functionality.
- If the link is not recovered, consider continuing the mission with only one communication channel or returning to the landing site.
- If both communication channels fail, check the last UAV position, shut down noise sources, and search for eye contact with the UAV.
Video Channel Failure
- Signs of a video channel failure include a jammed or black screen on the nose camera, a red "UAV link" alert, and operative primary channel with non-operative secondary communication.
- Actions include using the operative communication channel, setting the video transmitter to "High", verifying GDT and antenna connections, and restarting the camera.
- If the failure persists, consider replacing GCS components or aborting the flight.
GPS Failure
- A GPS failure is indicated by a GPS LOSS alert, a red UAV icon, spoofing detection, and the inability to maintain GPS flight modes.
- The UAV's position report, wind data, and true position may be unreliable during a GPS failure.
- The GDT's heading may be incorrect, and the Waldo Mission may not be possible.
- Actions during a GPS failure include maintaining a radius with the CG/Roll bar/HDG, using the camera to identify familiar locations, and verifying wind conditions.
Flight Control Malfunctions
- Wind speed and direction, as well as external temperature, can impact flight control.
Battery Malfunctions
- Battery malfunctions can be detected by observing flight battery voltage, flight battery percentage, and VTOL battery voltage.
- Red alerts for battery malfunctions indicate significant issues that require immediate action.
- Low battery levels can lead to motor shutdown.
- Battery malfunctions in takeoff require immediate QLAND.
- Battery malfunctions in flight can impact the ability to transition between landing modes.
- Actions taken based on battery alerts include considering landing, transitioning at low altitude, and referring to relevant battery malfunction documentation.
