3.4.2Automatic acquisition

The ARP can acquire up to ten targets automatically by setting an automatic acquisition area. When automatic acquisition is selected after acquiring targets manually, only the remaining capacity for targets may be automatically acquired. For example, if seven targets have been man- ually acquired, three targets may be automatically acquired.

The automatic acquisition area is 2.0 to 2.5 miles in range and ±45° on either side of the heading line in bearing. Targets being tracked in automatic acquisition are continuously tracked when switching to manual acquisition.
