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 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.
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, 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°.
