T-34C OUT-OF-CONTROL FLIGHT
stalled AOA is realized, the aircraft will depart with a rapid, nose-low roll in the
direction of applied rudder. Several more rapid rolls may result and a spin will
develop if control inputs are maintained. Post-departure recovery will be
accomplished quickly and easily by neutralizing the controls. Minimum entry
altitude for cross-control departure is 8000 feet AGL.
Establish the aircraft in 100 KIAS level flight, clean configuration.
Perform stall checklist and clearing turn.
Roll out of the clearing turn, reduce power to 200 ft-lbs. and set 100 KIAS best
(a). Roll 45° AOB in either direction.
(1). Reduce power toward idle.
(2). Increase back stick pressure while applying slight aileron toward the
(3). Input top rudder.
Increase control inputs until the aircraft departs controlled flight.
The possibility of overstressing the aircraft at airspeeds less than
VA (135 KIAS at maximum gross weight) exists due to VA
decreasing as gross weight decreases. The combination of this
lower VA at lower gross weights and asymmetrical loading
encountered during cross-control departures may overstress the
aircraft. Cross-control departures SHALL NOT be executed at
airspeeds in excess of 120 KIAS.
Departure will be in the direction of applied rudder.
IUT will assume control of the aircraft and recover in accordance with OCF
