Navigation General · ARPA
The ARPA 'trial maneuver' function allows the navigator to:
- ATest the radar transmitter
- BSimulate a proposed course and/or speed change to see its effect on CPAs before actually making it✓ Correct
- CAutomatically take control of the helm
- DErase all tracked targets
Explanation
The trial maneuver lets the operator enter a hypothetical own-ship course/speed (with a delay) and see the predicted CPAs of all tracked targets, confirming a planned avoidance maneuver will actually open the CPAs before committing to it.
