1 BRT (Brightness)
The BRT switch is a rotary control that is used to set the radar (raster)
brightness on the EFIS display.
2 TGT (Target Alert)
The TGT switch is an alternate- action, button 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 certain characteristics is detected in the monitored area, the target
alert changes from the green armed condition to the amber TGT
warning condition. (Refer to the target alert characteristics in table 3- 5
for a target description.) The amber TGT alerts the pilot as to potentially
hazardous targets directly in front and outside of the selected range.
When the alert is given, the pilot should select longer ranges to view
the questionable target. Target alert is inactive within the selected
range.
