4.3 System Annunciations

NOTE
Operating the G1000 NXi in the vicinity of metal buildings, metal structures,
or electromagnetic fields can cause sensor differences that may result in
nuisance annunciations during start up, shut down, or while taxiing. If one
or both sensed values are unavailable, it will be annunciated as a NO
COMP (no compare).
When an LRU or an LRU function fails, a red X is displayed on items associated with the
unsuccessful data. The following section describes common system annunciations.
Causes may include (but are not limited to):
• Unavailable Data
• Unreliable Data
• Failed Data due to aircraft/LRU connector wiring issue
• Failed Data due to power removal to the LRU
• Failed Data due to LRU hardware failure
• Dashes or underscores indicate uninitialized data. Upon applying system power,
certain display fields remain invalid as equipment begins to initialize.
NOTE
Everything should be operational within one minute of applying power. If
any display field remains flagged, begin troubleshooting the most likely
cause.
If data fields become invalid due to LRU failure, the PFD/MFD typically annunciates the
failure with a large red X, as shown in
