Message Advisory
Comments
SLCT NAV
– Select NAV on CDI for
approach.
The system notifies the pilot to set the CDI to the correct NAV receiver. Set the CDI to
the correct NAV receiver.
PTK FAIL
– Parallel track unavailable:
bad geometry.
Bad parallel track geometry.
PTK FAIL
– Parallel track unavailable:
invalid leg type.
Invalid leg type for parallel offset.
PTK FAIL
– Parallel track unavailable:
past IAF.
IAF waypoint for parallel offset has been passed.
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
crosstrack error.
The current crosstrack exceeds the limit, causing vertical deviation to go invalid.
VNV
– Unavailable. Excessive track
angle error.
The current track angle error exceeds the limit, causing the 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 G900X 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 or the GIA 63W/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°.
