Glideslope Deviation Scale
-
White
dots on each side of the display which, in
conjunction with the glideslope pointers,
indicate either 'above', 'below', or 'on
glideslope' during an ILS approach.
Compass Warning Flag
-
A red flag
labeled 'HDG' becomes visible in the
upper right quadrant of the display when-
ever the electrical power is inadequate or
the directional gyro is not up to speed.
Compass failures can occur which will not
be annunciated by the 'HDG" flag.
Therefore, periodic comparison with the
standby compass is advised.
NAV
Warning Flag
-
A red flag labeled
'NAV' becomes visible in the upper left
quadrant of the display whenever a usable
VOR or Localizer signal is not being
received. If RNAV is installed and the sys-
tem is in RNAV mode, both VOR and
DME
must be usable before the NAV flag will dis-
appear.
