Aggravated Approach Turn Stall

CHAPTER TWO

T-34C OUT-OF-CONTROL FLIGHT

NOTE

Ensure the rudder remains at neutral so as not to input pro-spin

controls.

vii. IUT will assume control of the aircraft and recover in accordance with OCF

Recovery Procedures.

Aggravated Approach Turn Stall

Description: This maneuver demonstrates the rapid and disorienting divergence to

departed flight that may occur following a rough application of stall recovery control

inputs while practicing approach turn stalls at altitude.

General: The maneuver will be flown by the Standardization Instructor and

recovered by the IUT. The aircraft will be flown through a normal approach turn stall

and during the recovery, control inputs will be initiated to induce a secondary stall.

The aircraft will depart by rolling in the direction of the applied rudder. Minimum

entry altitude for the aggravated approach turn stall is 8000 feet AGL.

Procedures

Perform the Stall Checklist and Clearing turn.

ii.

Establish the aircraft in a right-hand descending 90 KIAS approach turn (300 ft-

lbs., gear and flaps down, 30 AOB).

iii.

Simultaneously set 12 - 15 degrees noseup and reduce power to 200 ft-lbs.

iv.

Hold this attitude until the aircraft stalls, characterized by the nose pitching

down.

Simultaneously:

(a). Level wings.

(b). Add maximum power.

(c). Raise the nose 12 - 15 degrees above the horizon.

(d). Input a slight amount of left rudder.

CAUTION

Do not apply excessive or full rudder because a spin may develop.
