WARNING
FORCED STANDBY MODE MUST BE VERIFIED BY THE OPERATOR TO ENSURE SAFETY FOR GROUND PERSONNEL.
3 TGT (Target)
The TGT button is an alternate- action switch that enables and disables the radar target alert feature. Target alert is selectable in all but the 300- mile range. When selected, target alert monitors beyond the selected range and 7.5° on each side of the aircraft heading. If a return with target alert characteristics is detected in the monitored area, the target alert legend changes from the green T armed condition to the yellow TGT warning condition. (See the target alert characteristics in table 3- 2 for a target description.) These annunciations advise the pilot of potentially hazardous targets directly in front of the aircraft that are outside the selected range. When a yellow warning is received, the pilot should select longer ranges to view the questionable target. (Note that target alert is inactive within the selected range.)
Selecting target alert forces the system to preset gain. Target alert can be selected only in the WX or FP modes.
NOTE: In order to activate the target alert warning, the target must have the depth and range characteristics described in table 3- 2.
