Familiarization
Procedures
Complete the prestall and aerobatic checklist prior to performing the minimum radius turn. Begin the
maneuver at 300 KIAS, at the desired altitude, and aligned on a cardinal heading, prominent terrain
feature or section line for use as a visual reference. Roll into an approximate 85-degree AOB turn.
Simultaneously increase the power to MRT and back stick to obtain optimum AOA (17 units) while
continuing to maintain entry airspeed. You may sacrifice altitude as necessary to maintain airspeed
throughout the 360-degree turn.
Begin the reversal on the terrain feature you used to start the maneuver. Use a moderate rate of roll to
achieve 85 degrees AOB in the opposite direction. Release back stick pressure during the reversal to
prevent the nose attitude from ballooning. As you roll into an 85-degree AOB turn in the opposite direction,
feed in back stick to maintain optimum AOA (17 units) and adjust the nose attitude as required to maintain
airspeed. Maintain power at MRT, optimum AOA, and entry airspeed throughout the 360-degree turn. Roll
out of the turn so the nose of the aircraft reaches the referenced terrain feature. As your wings reach
level, adjust the power and the nose attitude to maintain 300 KIAS in level flight.
NOTE: Angle of attack is very sensitive during the minimum radius turn: small changes in g will cause a
significant change in the AOA.

Techniques
Remember, the airspeed is directly related to the nose attitude. As you decrease AOB (and therefore raise
your nose attitude), your airspeed will decrease. As you increase AOB (and therefore lower your nose
attitude), your airspeed will increase.
