UAS System Safety Features

The heart of any UAS autopilot system should hold safety as a paramount feature.

The Hawk system gives safety matters top priority and features many monitoring options should a fault occur.

Some of these are listed here and others are in testing or development.

  • Startup health checks:  Take off is disabled if the aircraft is not flight ready.
  • Return on link fail option retraces planned route in the event of link loss/failure.
  • In-flight Terrain collision detection (based on terrain elevation model) gives audible warning that collision with terrain is immanent.
  • Constant in flight checking for Minimum Safe Altitude (MSA) with audible warning if descending below MSA.
  • Waypoint route checks for terrain collision and no line of sight (LOS).
  • Audible warnings for detected problems.
  • Battery consumption monitoring to estimate remaining flight time, GCS display of maximum return range together with audible warnings for point of no return.
  • Dead reckoning mode in the event of GPS failure or jamming.
  • GPS/Barometric altitude trade-off adjustment provides altitude redundancy.
  • Emergency landing point preset options for fully automated recovery during a link failure.
  • Manual flight termination (parachute release)
  • Automatic flight termination - based on internal system health monitoring software. Identifies over limits of pitch and roll attitudes.
  • External electrically isolated flight termination system that releases the parachute in the event of a critical autopilot power or control failure
  • Software selectable strobe light for night operations.
  • GCS display warnings when entering Direct Control Mode.
  • Ground station aircraft handover/recovery option on GCS failure.
