ATA OPERATION

■ ATA (Automatic Tracking Aid)

By automatically tracking the target chosen with the cursor key, the closest point of approach (CPA) and the time
to closest point of approach (TCPA) limit of your vessel and a target are calculated.
ATA function is designed to sound an alarm when the CPA and TCPA fall below a set value (the approach watch
area).
Only targets in the 0.25 to 16 NM range that are displayed with a high luminosity (strong return signal) can be
selected as ATA targets.
• A maximum of 10 targets can be plotted on the screen.
• Plot positions are identified by an approved symbol mark (p. 33) and associated plot number.
• The target and vector line will move across the screen at the rate and direction defined by the calculated true
or relative course and speed.
• The vector line is displayed on the target.
