Aircraft Does Not Disarm Upon Landing
WARNING: Failure of disarm after enabling safety switch can lead to an commanded takeoff without crew going through the preflight procedure. This is a condition, which if procedures are not strictly observed, could result in damage to or destruction of equipment, loss of mission effectiveness, or health hazards to personnel. Specifically, this could lead to minor injuries if the ground crew is too close to spinning propellers.

INDICATIONS

  1. Aircraft has landed and propellers continue to spin.

  2. Message “DISARM” does not show up on either GCS.

  3. Safety Switch does not automatically turn on.

POSSIBLE CAUSES

  1. FMU Failure

  2. Incorrect or erroneous altitude measurement(s)

FAILSAFE BEHAVIOR

There is no Failsafe for this emergency.

PROCEDURE

FAILURE TO DISARM ANNOUNCE

When one or more of the indicators is observed and the aircraft has had both landing gears touch down on the ground, the RPIC is to announce the above notification on the voice communication channel in use by the hub. This is imperative to ensure crew member awareness of an off-nominal situation involving the aircraft operation. The voice communication devices (i.e. handheld radios) as part of the RPIC Control Station accessories should be utilized to perform this task. The announcement should be made clearly with the exact wording used as shown above. While not required, it is advisable to clearly articulate the announcement more than one time to reduce the likelihood of crew member unawareness to the situation.

AMC: Emergency Shutdown ENGAGE

Select the “Emergency Actions” button at the top of the AMC application on the RPIC Tablet. Once pressed, a notification and confirmation popup will appear in the center of the screen.

Emergency Actions Button

Hold to Confirm Button

Press and hold the “Hold to Confirm” button to execute the Emergency Shutdown. Once executed, the motors will immediately terminate operation (i.e. stop) and the parachute will deploy.

After deployment, the aircraft is required to be serviced in accordance with the UMM by qualified maintenance personnel.

CAUTION: Ensure the area around the aircraft is clear of persons or obstructions within a 16ft diameter (minimum) prior to engaging emergency shutdown. Failure to strictly observe this condition could result in damage to or destruction of equipment, loss of mission effectiveness, or health hazards to personnel.
