Sea Scout and ARPA Trial Manoeuvre
Using the Sea Scout (chapter 2.10) function it is possible and helpful to use the
ARPA Trial Manoeuvre as a second function. The operator can see the “No- Go
Areas” and find the gap between these areas per trial manoeuver.
Alarms and warnings during the trial manoeuvre:
Real alarms
The ARPA tracking system continues running in the background. If there is a
real close range situation (target enters the CPA/TCPA zone limits), an
automatic alarm is generated. The target symbol flashes and a corresponding
alert text message appear in the alarm display.
Temporary alarms
If a close range situation occurs during the trial manoeuvre, the target symbols
flash.
