Entering Own Ship's Speed - Furuno FR-1500 MARK-3 Series User Manual

2.4 Entering Own Ship's Speed

The ATA requires own ship's speed and heading 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.

Notes:
1) IMO Resolution A.823(19) for ARPA recommends that a speed log to be interfaced with an
ARPA should be capable of providing through-the-water speed. This applies to the ATA 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" appears if no log signal is present for 30 seconds
while the ship speed has been more than 5.0 kt.
