T-34C CONTACT

General. Plan your clearing turn so as to roll out on a good section line or with the nose

aimed at a prominent reference point. When performing the maneuver make your control inputs

smooth, brisk and positive.

Procedures

CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the

Aerobatic Checklist. CLEARING TURN: Commence a clearing turn and roll out

with the required ground references.

Commence the maneuver by smoothly raising the nose to place the exhaust stacks on

the horizon while keeping the wings level. Stop nose movement by relaxing

backstick pressure.

Roll briskly in either direction by applying lateral stick deflection and rudder in the

same direction. The amount of stick deflection will determine your rate of roll. If the

rate of roll is too slow, the nose will fall below the horizon and a rolling pullout will

result.

As you approach the wings level attitude, ease out aileron and rudder pressure to

recover with the wings level and the nose attitude reset for level flight.

Common Errors

Failure to relax the back stick pressure prior to rolling. Backstick pressure is required

only to set the initial nose high attitude. Failure to relax the backstick pressure will

cause the nose to follow an arcing path rather than having the aircraft roll about its

longitudinal axis. It will also cause the nose to drop rapidly while passing the

inverted position.

Delaying initiation of the roll once the nose high attitude is set. This causes excessive

airspeed decay, which results in a sluggish roll performance.

Failure to input sufficient rudder in the direction of roll. The high roll rates required

for the Aileron Roll generate considerable adverse yaw. This must be compensated

for with sufficient rudder in order to maintain balanced flight.
