T-34C CONTACT

General. This maneuver offers a quick means of reversing the direction of flight while

trading excess airspeed for increased altitude. Remember to select a long, well defined section

line which extends behind as well as in front of you.

Procedures

CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the

Aerobatic Checklist. CLEARING TURN: Commence a clearing turn. During the

last 90 of turn, lower the nose slightly and accelerate to 200 KIAS. Roll out of the

clearing turn on or parallel to a section line with 200 KIAS. The increased airspeed

will require a slight amount of left rudder to maintain balanced flight.

Recheck the wings level and clear the airspace above you. Just prior to entry, check

and report the entry altitude over the ICS. Commence the AGSM and immediately

start a smooth straight pull-up, accelerating to 3.5 Gs within 2 - 3 seconds. Do not

use the aileron.

Recheck the wings level as the nose passes through the horizon. Adjust stick pressure

as necessary to keep the nose moving at a constant rate. Increase right rudder

pressure as airspeed decreases.

Shortly after passing the vertical position, tilt your head back and visually locate the

opposite horizon. Correct with aileron as necessary to maintain the wings parallel to

the horizon. Check the nose in relation to the section line and correct directional

deviations as necessary by adjusting the rudder input.

As the nose approaches a point 20 above the opposite horizon ("canopy bow" on the

horizon,) slow the rate of nose movement by neutralizing backstick pressure.

Commence a roll in either direction to the upright position using aileron and rudder.

Anticipate the need for slight forward stick pressure as the aircraft passes 90 of roll.

The maneuver is complete when the aircraft is once again in the level flight attitude

on the reciprocal heading. The airspeed should be approximately 100 KIAS. The

nose attitude will therefore be slightly high.

Common Errors

Same common errors as the first half of a Loop.

Commencing the roll to upright attitude either too early or too late.

Utilizing improper rudder and/or poorly coordinated rudder inputs during the roll.
