Comments
The aircraft is inside the airspace.
Data link avionics were not configured correctly
and therefore will not be able to communicate
with the ground network.
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.
GPS integrity is insufficient for the current phase
of flight.
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°.
The PFD and/or MFD has incorrect software
installed. The system should be serviced.
The specified GDU has different software
versions installed. The system should be
serviced.
One of the terrain or obstacle databases
required for TAWS in the specified GDU is
missing or invalid.
The specified GDU's backlight calibration cannot
be found or is invalid. The system should be
serviced.
The MFD configuration settings do not match
backup configuration memory. The system
should be serviced.
The MFD is overheating and is reducing power
consumption by dimming the display. If
problem persists, the system should be serviced.
