Comments
The current vertical waypoint can not be reached
within the maximum flight path angle and vertical
speed constraints. The system automatically
transitions to the next vertical waypoint.
The lateral flight plan contains a procedure turn,
vector, or other unsupported leg type prior to the
active vertical waypoint. This prevents vertical
guidance to the active vertical waypoint.
The current track angle error exceeds the limit,
causing the vertical deviation to go invalid.
The current crosstrack exceeds the limit,
causing vertical deviation to go invalid.
A parallel course has been selected, causing
the vertical deviation to go invalid.
The position of the selected waypoint [xxxx]
is not calculated based on the WGS84 map
reference datum and may be positioned in
error as displayed. Do not use GPS to navigate
to the selected non-WGS84 waypoint.
The system is no longer receiving data from
the traffic system. The traffic device should be
serviced.
A data path connected to the GDU, GDL 69A,
or the GIA 63/W has failed.
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°.
Synthetic Vision is disabled because the aircraft
is not within the boundaries of the installed
terrain database.
