Description and Operation
Inst.10.17
FMC Map Data Failure (Plan Mode)
Loss of map data results in the loss of PLAN Mode. Selection of PLAN mode
results in the display of NO PLAN MODE in amber in the center of the display.
Bearing Pointer Data Failure
Failure of bearing pointer data results in the removal of the associated bearing
pointer and replacement of the digital value at the bottom of the display with an
amber X.
DME Failure
Failure of DME data will cause the associated digital value at the bottom of the
display to be replaced by an amber X. The DME data associated with the CDI
distance is removed and flagged with an amber X.
CDI Source Failure
Failure of the CDI source results in removal of the course deviation indicator
(pointer and scale), with the display of an annunciation (VOR, ILS) FAIL in red
within the compass rose.
CDI Source Annunciation
When an alternate CDI source (VOR, ILS) has been selected (Capt. on 2 or F/O
on 1) and the ND is in VOR or APPR modes, the source is annunciated in amber
in the top right corner of the ND.
Possible CDI source annunciations on the ND are as follows:
• ILS1 on F/O ND.
• ILS2 on Capt. ND.
• VOR1 on F/O ND.
• VOR2 on Capt. ND.
No Computed Data Indications
When data is marked as No Computed Data (NCD) by its source, all symbology
dependent on that data will be removed from the display. No failure flags will be
displayed for NCD data.
IRS Source Annunciation
The selected heading/track source is not annunciated if the current source is the
normal on-side source for the display. If the auxiliary source is selected, it is
annunciated in white to the left of the heading/track display area. When the
Captain and First Officer source is the same, the annunciation is amber on both
NDs.
