Winch Failsafe Failure - Land in Place
WARNING: Failure of Winch Failsafe may result in entanglement of the aircraft in the winch line resulting in loss of aircraft, damage to property, and injury to persons (MINOR)

INDICATIONS

  1. Winch Failure - Package Not Releasing, Section 4.3.2.2 has been attempted without a successful result (i.e. complete release of line and external load)

  2. External load and line still connected to winch after winch freespool command has been issued

NOTE: Winch Status “FAILSAFE” does not indicate the winch failsafe (see FAILSAFE BEHAVIOR below) is being performed. It only indicates that the winch is in an unhealthy state.

POSSIBLE CAUSES

  1. Winch failure

FAILSAFE BEHAVIOR

After the third and final delivery attempt, the winch automatically enters into a Hold state and awaits commands from the RPIC or the automated loss of comms failsafe.

PROCEDURE

EMERGENCY WINCH FAILURE ANNOUNCE

The RPIC is to announce the voice comms “Winch Failure” once emergency conditions are identified using the indications information above.

VO: Location — RELOCATE TO AIRCRAFT POSITION

The RPIC shall communicate with the VO to relocate to the aircraft position.

Using video feed, determine if area below aircraft is clear for landing VERIFY

The RPIC is to use the ASMIRA video feed on the RPIC Control Station to inspect the landing area directly beneath the aircraft.

If Landing Area is clear:

Use video feed to determine wind effects on external load INSPECT

The RPIC is to use the ASMIRA video feed on the RPIC Control Station to determine the wind effects on the external load.

AMC Click to Fly: Navigate aircraft in opposite direction of wind and package ENGAGE

The Goto command is located on the action toolbar on the upper left side of the AMC Fly View on the RPIC Tablet. Selection of this command will result in the aircraft flying a direct path to the desired waypoint set on the map by the RPIC. The RPIC must set the waypoints in a manner that ensures the aircraft does not fly over No Fly Areas.

Goto Action Button AMC

Once the “Goto” button is selected, the RPIC will create a waypoint by clicking at the desired point on the map. Once a waypoint is selected, a small point can be seen on the Fly View map interface.

Goto Waypoint Selection AMC

Once the desired waypoint is selected, the AMC application will require RPIC confirmation. Press and hold the “Hold to Confirm” button popup found at the bottom of the Fly View map interface.

Goto Waypoint Confirmation AMC

Once the Goto command is confirmed, the aircraft will begin to fly a direct path to the set waypoint.

If Landing Area is obstructed:

VO: Clear the landing area VERIFY

The VO shall clear the landing area and communicate the area is clear to the RPIC. Aircraft remains in Hold Mode until this time.

Use video feed to determine wind effects on external load INSPECT

The RPIC is to use the ASMIRA video feed on the RPIC Control Station to determine the wind effects on the external load.

Goto Waypoint Confirmation AMC

Once the Goto command is confirmed, the aircraft will begin to fly a direct path to the set waypoint.

Land Mode ENGAGE

The Land command (Land Now) is located on the action toolbar on the upper left side of the AMC Fly View on the RPIC Tablet. Selection of this command will result in the aircraft entering Land flight mode and will begin descending for landing.

Land Action Button AMC

Once the “Land” button is selected, the AMC application will require RPIC confirmation. Press and hold the “Hold to Confirm” button popup found at the bottom of the Fly View map interface.

Land Confirmation AMC

Once the Land command is confirmed, the aircraft will begin descending to the ground. Once touchdown is achieved, the aircraft will automatically detect the landing and will disarm.

Procedure Complete
NOTE: Aircraft will need to be recovered by personnel.
