AIS CPA/TCPA Alarm

A dangerous AIS target is one whose CPA and TCPA are within the range of the CPA
and TCPA limits set in the information area. A dangerous AIS target is displayed as a
blinking target symbol in red as long as you acknowledge the "AIS CPA/TCPA" alert.
Then the target symbol is displayed in red color.
When a target whose CPA or TCPA is within the limits set here the buzzer sounds and
the Alert 536 "AIS CPA/TCPA" appears in the [Alert] box.
1. Select the [TT/AIS] page from the [Overlay/NAV Tools] box.
