Search and Rescue (SAR) Patterns
When enabled by EFIS system limits, the pilot can create one SAR pattern
at an eligible flight plan waypoint and only one waypoint within the active
flight plan. The current position of the aircraft is determined relative to that
desired path for lateral deviation for display on the GPS/SBAS CDI. In most
cases, the IDU auto-sequences from one waypoint to the next similar to all
other flight plan sequencing along the flight path.
The SAR option is available for any waypoint except the following:
1) Suppressed
waypoint
2) Skipped
waypoint
3) Manual termination waypoint
4) Waypoint that is part of an IFR or VFR approach
5) Holding pattern waypoint
6) SAR pattern exit waypoint
7) Waypoint that begins a departure procedure
8) Parallel offset entry or exit waypoint
9) Dynamic termination waypoint (altitude termination, DME termination,
radial termination or intercept termination)
SAR patterns can be created in the
RUN DEMONSTRATOR/TRAINING
PROGRAM
Ground Maintenance Page or the EFIS Training Tool. After the
SAR pattern is created and saved, that flight plan can be uploaded to any
IDU or all IDUs in an aircraft for later use.
The desired flight path is created from a sequence of straight, left, and right
turning leg segments to provide smooth skyway, GPS/SBS CDI, and lateral
autopilot guidance. SAR patterns are drawn at the lowest of holding or
procedure speed.
