Message Comments
UNABLE V WPT
– Can’t reach
current vertical waypoint.
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.
VNV
– Unavailable. Unsupported
leg type in flight plan.
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.
VNV
– Unavailable. Excessive track
angle error.
The current track angle error exceeds the limit,
causing the vertical deviation to go invalid.
VNV
– Unavailable. Excessive
crosstrack error.
The current crosstrack exceeds the limit,
causing vertical deviation to go invalid.
VNV
– Unavailable. Parallel course
selected.
A parallel course has been selected, causing
the vertical deviation to go invalid.
NO WGS84 WPT
– Non WGS 84
waypoint for navigation -[xxxx]
The selected waypoint [xxxx] does not use the
WGS 84 datum. Cross-check position with
alternate navigation sources.
TRAFFIC FAIL
– Traffic device has
failed.
The system is no longer receiving data from
the traffic system. The traffic device should be
serviced.
FAILED PATH
– A data path has
failed.
A data path connected to the GDU, GSD 41,
GDL 69, or the GIA 63/W has failed.
MAG VAR WARN
– Large magnetic
variance. 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°.
SVS
– SVS DISABLED: Out of
available terrain region.
Synthetic Vision is disabled because the aircraft
is not within the boundaries of the installed
terrain database.
