12
47
What do you do if you have a Gimbal Disable condition with an asterisk?
Do not initiate AN/DAs- reset
48
What happens when tracker enters Coast Mode?
When tracked target is lost because it is obscured. LOS continues to move at last valid rate and direction until target reacquired or track cancelled. Coast mode indicated by track gate corners flashing. If system fails to reacquire track after 5 seconds it automatically cancels and reverts to rate mode.
