Action
Contact dealer for service.
Verify glideslope deviation
indications with another source
and crosscheck final approach
fix crossing altitude. If another
glideslope source is not available
for verification, fly a GPS based
approach. Contact dealer for
service.
Fly an approach that does not use
the glideslope receiver (VOR, LOC,
GPS). Contact dealer for service.
Ensure that the waypoints on the
GNS have unique names before
transferring to the GTN to avoid
overwriting existing waypoints.
Remove some of the waypoints
from the catalog to make room for
the waypoints from the GNS.
The data transfer should be
reattempted.
Wait for GPS satellite geometry
to improve. Ensure the aircraft
has a clear view of the sky. Use a
different GPS receiver or a non-
GPS based source of navigation.
Contact dealer for service.
