HDG FAULT
– AHRS1 magnetometer
fault has occurred.
A fault has occurred in the #1 GMU 44. Heading is flagged as invalid. The ADAHRS
uses GPS for backup mode operation. The system should be serviced.
HW MISMATCH
– GIA hardware
mismatch. GIA1 communication
halted.
A GIA mismatch has been detected, where only one is SBAS capable.
HW MISMATCH
– GIA hardware
mismatch. GIA2 communication
halted.
INSIDE ARSPC
– Inside airspace.
The aircraft is inside the airspace.
INVALID ADM
– Invalid ADM: ATN
communication halted.
Data link avionics were not configured correctly and therefore will not be able to
communicate with the ground network.
LOCKED FPL
– Cannot navigate
locked flight plan.
This occurs when the pilot attempts to activate a stored flight plan that contains
locked waypoint. Remove locked waypoint from flight plan. Update flight plan with
current waypoint.
LOI
– GPS integrity lost. Crosscheck
with other NAVS.
GPS integrity is insufficient for the current phase of flight.
LRG MAG VAR
– Verify all course
angles.
The GDU’s internal model cannot determine the exact magnetic variance for
geographic locations near the magnetic poles. Displayed magnetic course angles may
differ from the actual magnetic heading by more than 2°.
MANIFEST
– MFD1 software
mismatch, communication halted.
The PFD and/or MFD has incorrect software installed. The system should be serviced.
MANIFEST
– PFD1 software
mismatch, communication halted.
MFD SOFTWARE
– MFD mismatch,
communication halted.
The specified GDU has different software versions installed. The system should be
serviced.
MFD TERRAIN DSP
– MFD Terrain
awareness display unavailable.
One of the terrain or obstacle databases required for TAWS in the specified GDU is
missing or invalid.
MFD1 BACKLIGHT CALIBRATION
–
MFD1 calibration. Return for repair.
The specified GDU’s backlight calibration cannot be found or is invalid. The system
should be serviced.
MFD1 CONFIG
– MFD1 config error.
Config service req’d.
The MFD configuration settings do not match backup configuration memory. The
system should be serviced.
MFD1 COOLING
– MFD1 has poor
cooling. Reducing power usage.
The MFD is overheating and is reducing power consumption by dimming the display.
If problem persists, the system should be serviced.
MFD1 DB ERR
– MFD1 obstacle
database error exists.
The MFD detected a failure in the obstacle database. Ensure the data card is properly
inserted. Replace data card. If problem persists, the system should be serviced.
MFD1 DB ERR
– MFD1 obstacle
database missing.
The obstacle database is present on another LRU, but is missing on the specified LRU.
MFD1 DB ERR
– MFD1 terrain
database error exists.
The MFD detected a failure in the terrain database. Ensure the terrain card is properly
inserted in display. Replace terrain card. If problem persists, the system should be
serviced.
MFD1 DB ERR
– MFD1 terrain
database missing.
The terrain database is present on another LRU, but is missing on the specified LRU.
