T-34C AIRCRAFT SYSTEMS FAMILIARIZATION
1804. AUXILIARY FLIGHT CONTROLS
Wing flaps are high-lift devices used to increase lift during low speed flight. The T-34C utilizes
slot type flaps which are attached to the trailing edge of the wing near the root. The flaps are
operable from either cockpit and a flap position indicator labeled in percent is located on the left
side on each instrument panel. The flaps will extend or retract electrically in approximately 10
seconds. A 28-volt DC flap motor is controlled by a three-position airfoil-shaped lever located
on the left sidewall in both cockpits. Limit switches in the left wing cut power to the motor
when the flaps are fully extended or fully retracted. Raising the lever to UP retracts the flaps,
depressing the lever to DN extends them, and placing the lever in the center OFF position will
stop flap travel at an intermediate position. (OFF is not normally used.) No emergency system
is provided for flap operation in the event of a complete electrical failure.
The flap indicator located on the left side of the instrument panel will indicate the flaps' position
as a percent of full flaps (30°). Full up = 0% and full down = 100%. Flap indication is taken
from the left flap.
