Sirius Pro: Dealing with Disturbances

0 0

Dealing with Disturbances: Issue - Manned aircraft in the Project Area

  • Switch the RC controller into Assisted Flight Mode.
  • Descend and avoid the manned aircraft while in Assisted mode. 
  • Once the aircraft has left the project area, switch the RC controller to Automatic to resume mission.
  • If the manned aircraft remains in the project area, land the UAV in Assisted Mode.  

 

Dealing with Disturbances: Issue - UAV GNSS Tracking Loss

  • Switch the RC controller into Assisted Flight Mode.
  • Land the UAV in Assisted Mode. 

 

Dealing with Disturbances : Issue - RC Link Loss

  • Attempt to re-establish RC Link with the UAV (i.e. charge the battery). 
  • If using Assisted Mode landing, allow the UAV to finish it’s mission and return to the home position. 
  • If RC link cannot be re-established, allow the UAV to circle down once the battery is depleted. 
  • If using Spot Landing, allow the UAV to land automatically. 

 

Dealing with Disturbances : Issue - WLAN Connector Link Loss

  • Check the LED’s on the WLAN Connector and PC Wi-Fi settings. Attempt to reestablish comms. 
  • If using Assisted Mode landing, allow the UAV to finish it’s mission and return to the home position. 
  • Switch the RC controller into Assisted Flight Mode.
  • Land the UAV in Assisted Mode. If using Spot Landing, allow the UAV to land automatically

 

Dealing with Disturbances : Issue - RC and WLAN Connector Link Loss

  • Attempt to re-establish communication to RC or WLAN Connector. Check batteries and settings. 
  • If reconnected to the RC, switch the RC to Assisted mode and land the UAV.
  • If reconnected to the WLAN connector, select Return Home. If Return Home is selected, allow the UAV to circle around the home position until comms are established or the battery is depleted. 

 

Dealing with Disturbances : Issue - Motor RPM Loss

  • Switch the RC controller into Assisted Flight Mode.
  • Attempt to land the UAV safely in Assisted Mode.
  • The user can only glide the UAV with the motor off. Will only be able to control left/right and down
  • Cannot raise UAV altitude (except via the wind). 

 

Dealing with Disturbances : Issue - UAV Flyaway

  • Switch the RC controller into Assisted Flight Mode.
  • Land the UAV in Assisted Mode. 

 

Dealing with Disturbances : Issue - GNSS RTK Correction Loss

  • Check the GNSS antenna cable connection to WLAN Connector and GNSS Antenna.
  • Confirm that the Internal base station is started in MAVinci Desktop.
  • After landing the UAV, clear GNSS NVRAM on the UAV/Connector and restart the Internal Base.

 

Dealing with Disturbances : Issue - Spot Landing is continually aborting

  • Switch the RC controller into Assisted Flight Mode.
  • Land the UAV in Assisted Mode

Dealing with Disturbances : Issue - UAV High Temp. warning messages

  • If occurring while on the ground, cool the UAV down by placing in the shade, in air conditioning, etc. before starting flight operations. 
  • If occurring during flight, switch the RC controller into Assisted Flight Mode. Land the UAV

Dealing with Disturbances : Issue - Changing Weather conditions in flight

  • If the UAV is prepared to fly in precipitation, continue the mission and land the UAV.
  • If not, switch the RC controller into Assisted Flight Mode. Land the UAV in Assisted mode.
  • See section 4.2.2 of the MAVinci user’s manual to prepare the UAV to fly in precipitation.

 

Dealing with Disturbances : Issue - UAV Crash

  • If the UAV has completed the mission an is still powered on after the crash, attempt to download the flight and photo logs and remove the camera SD card so matchings can be generated from the collected data.
  • If the wings are damaged in the crash, repair if possible, replace if necessary.
  • If the either stabilizer is damaged in the crash, repair if possible, replace if necessary.
  • If any airfoil screws or fasteners are damaged, replace them. 
  • If any propellers are damaged after landing or crashing, replace them. 
  • If the UAV engine is damaged or doesn’t spin properly, replace the engine.
  • If the internal plastic skeleton is damaged in the crash, cease flight operations. The UAV engine mounts to the internal plastic skeleton. This will need to be repaired by Topcon before resuming operations
  • If the UAV fuselage is significantly damaged (i.e. in pieces, any of the internal boards are dislocated) in the crash, cease flight operations. This will need to be repaired by Topcon before resuming operations.
  • If the UAV camera or camera lens is damaged, cease flight operations. This will need to be repaired by Topcon before resuming operations.
  • If any of the wing or stabilizer electrical connectors are damaged on the UAV fuselage, cease flight operations. This will need to be repaired by Topcon before resuming operations.
  • If the UAV motor is still running after landing or crashing, turn off the engine immediately using the Landing switch on the RC controller
  • If the UAV LiPo battery is damaged in any way, attempt to clear it from the UAV cockpit and do not use it ever again.
  • If the UAV catches fire, attempt to put the fire out if possible or contact the proper authorities
