Radar Observer · ARPA — Trial Maneuver
The ARPA trial-maneuver function allows the navigator to:
- AAutomatically steer the ship clear
- BSimulate the effect of a proposed course/speed change on all tracked targets before executing it✓ Correct
- CErase all targets from the display
- DIncrease transmitter power
Explanation
Trial maneuver computes how a planned alteration of own course and/or speed would change the CPA/TCPA of every tracked target, so the officer can verify the maneuver clears all traffic before ordering it. A time delay can be set for when the maneuver will start.
