PFDs change to amber when a target of the re-
quired characteristics is detected. See Table 16-
8 for the target depth and range characteristics
that trigger the target alert annunciator. Upon
receiving the target alert annunciation, the op-
erator should select an extended range to view
the questionable target. Target alert is func-
tional (if selected) even when radar is not se-
lected for display on the PFDs/MFD.
SECT (Sector Scan)
The SECT pushbutton is used to select either the
normal 14 looks per minute 120° scan or the
faster update 28 looks per minute 60° scan.
When sector scan is selected the radar looks +
30° from the airplane heading.
