Fig. 19 Paused Altitude Rate
Sudden indicator display of a ground height is
indicative of an aircraft antenna ground plane
bonding problem or RF feeder cable
termination problem, resulting in leakage
between TX and RX antennas. This usually
manifests at higher altitude when the reflected
TX power seen by the receiver falls below the
level of leakage.
Altitude may now be manually-slewed using the
Data-entry popup.
