Do not cycle the landing gear when it is in transit. The motor
should stop before selecting the opposite direction of travel.
Otherwise, you may damage the motor and drive mechanism.
Three position indicators adjacent to the gear handle are located in both cockpits. Each indicator
shows cross-hatching (barber pole) if the related gear is in any unlocked condition or whenever
the electrical system is not energized. The word "UP" appears if the gear is up and locked; and a
"wheel" shows on each indicator when the related gear is down and locked. The gear position
circuit breaker, placarded POSN, is located on the landing gear section of the front cockpit
circuit breaker panel.
In addition to the gear position indicators, an audio-visual warning system is installed to provide
indications of any abnormal or unsafe gear position. A flashing red "WHEELS" light on the
instrument panel, a light in the gear handle, a warning horn, and an audio tone (1000 Hz) warns
the pilot that one or more of the following conditions exists:
The flaps have been extended (regardless of amount) prior to extending the landing
The power lever has been retarded below approximately 75% N1 with the gear not
extended or when the aircraft is on the ground with the gear handle placed in the UP
The EPL has been retarded below approximately 75% N1 (with PCL at idle), with the
gear not extended .
Both the PCL and EPL are simultaneously advanced beyond the 75% switch with the
During extended power-off operations with the gear up, depressing the "WARNING HORN
SILENCE" button adjacent to the landing gear handle will silence the warning horn. The
"WHEELS" light will continue to flash. However, whenever the flaps are down (and the gear is
up), the warning horn cannot be silenced.
Do not silence the aural warnings when commencing an approach
for landing by any method other than extending the landing gear.
An Inboard Landing Gear Door Position Indicator system has been retrofitted on many of the
aircraft. The purpose is to indicate, via annunciators (located on both cockpit panels between the
WHEELS annunciator light and the MASTER CAUTION annunciator), when the inboard
landing gear doors are not in the closed and locked position when the landing gear is not in
transit (i.e.,. fully up or down). Refer to the T-34C NATOPS Manual Chapter Two for further
