Note that there are some situations when the selected transponder mode may be
different from the status annunciated in the Transponder Status Area. For example,
if you select ALT mode, but there is a squat switch installed, it will keep the
transponder in GND mode until the aircraft has become airborne. The requested
ALT mode would then be activated.
