3. Confirm Aircraft altitude indicator tracks altitude
smoothly from Start Altitude to Stop Altitude, and that no
indicator flag is in view.
STEP PROCEDURE
NOTE:
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.
