INDICATIONS

  1. The RPIC observes through visual line of sight, or through telemetry/remote sensing (such as sensors, cameras, or the Flight Alerter application), that their aircraft is in close proximity to another object or aircraft, and the flight paths are converging with insufficient separation distance.

POSSIBLE CAUSES

  1. Intruding aircraft in area of operation

  2. Loss of situational awareness

  3. Software failure

FAILSAFE BEHAVIOR

There is no Failsafe for this emergency.

PROCEDURE

COLLISION IMMINENT ANNOUNCE

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

INTRUDING AIRCRAFT LOCATION ANNOUNCE

UNCREW: DEFENSIVE CROUCH SELECT

Select the “Defensive Crouch” button that is located in the top left corner of the Uncrew Mission Console on the RPIC Control Station.

Uncrew Defensive Crouch Button

Once the “Defensive Crouch” button is selected, the aircraft comes to a stop and begins descending to 80 ft AGL.

NOTE: If LiDAR Rangefinder is not operational, use AMC Altitude slider to complete the descent maneuver.

Video Feed MONITOR

The RPIC is to use the ASMIRA video feed on the RPIC Control Station to continue monitoring the area directly beneath the aircraft looking for obstacles.

If obstacle is observed in descent path:

Uncrew: Pause SELECT

Select the “Pause” button that is located in the top left corner of the Uncrew Mission Console on the RPIC Control Station.

Uncrew Pause Button

Once the “Pause” button is selected, the aircraft stops its descent and holds in place until the next command is given.

Maintain current altitude and position, proceed to Uncrew: Resume

Altitude is equal to 80 feet based on LiDAR Rangefinder VERIFY

Inspect the current AGL Altitude using the telemetry in the bottom right corner of the Fly View map interface on the RPIC Tablet. The LiDAR Rangefinder (Distance Sensor) altitude is designated by “DS:”.

Telemetry Information AMC

Uncrew: Resume SELECT

Select the “Resume” button that is located in the top left corner of the Uncrew Mission Console on the RPIC Control Station.

Resume Button
