3 STAB (Stabilization) Button
Pushing the STAB button toggles attitude stabilization on and off. When
turned off, OFF is annunciated above the button.
4 TGT (Target) Button
Pushing the TGT button toggles the radar target alert feature on and off.
Target alert is selectable in all but the 300--mile range. When selected,
the system 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 annunciator changes
from the armed condition (T) to the warning condition. (TGT) (See the
target alert characteristics in Table B--1 for a target description.) The
TGT annunciator advises 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 weather or flight plan modes.
NOTE: In order to activate the target alert warning, the target must
have the depth and range characteristics described in Table
B--1.
