Note: The ATA plot is automatically turned on whenever the automatic acquisition area or guard ring is activated or a target is se- lected for target-based speed input.

5.Entering Own Ship’s Speed

The ATA requires own ship’s speed and head- ing data. Of these, the speed data can be entered automatically from a speed log, navaid or manually through the menu.

Note: It is customary to use a speed relative to water for collision avoidance and a speed over the ground for navigation purpose.

* NAV shown on R-type only.

Notes:

1)IMO Resolution A.823(19) for ARPA rec- ommends that a speed log to be inter- faced with an ARPA should be capable of providing through-the-water speed. This shall apply to the ATA operation as well.

2)Be sure not to select LOG when a speed log is not connected. If the log signal is not provided, the ship’s speed readout at the screen top will be blank.

3)SPEED xx.x and “SIGNAL MISSING LOG” appear if no log signal is present for 30 seconds.
