General. The Wingover will develop your ability to smoothly control the aircraft in

balanced flight through constantly changing attitudes and airspeeds. It is a slow and gentle

maneuver when properly executed. No abrupt control movements are necessary. The maneuver

may be initiated in either direction and is always performed in a series of two. You should

therefore complete the series on the same heading that the first Wingover was initiated. Flying

the maneuver in series will enable you to develop a "feel" for the changing control pressures and

the rhythm of the maneuver. Successive Wingovers, when continued without interruption, serve

as clearing turns for the next series.

When your instructor first demonstrates the Wingover, it is of primary importance that you

acquire a mental picture of the path through which the aircraft is flying. Notice the appearance

of the nose and the wings in relation to the ground and the horizon at various points during the

maneuver. Once you are able to visualize this, the Wingover is merely a matter of flying the

aircraft in balanced flight through this pattern. Since you are learning to fly the aircraft in a

predetermined pattern, keep your scan primarily outside of the cockpit. Use your instruments

only for an occasional reference to crosscheck your sensory impressions.

The rate of roll should be constant throughout the maneuver. The nose should always move at a

constant rate in relation to the horizon as it describes arcs, first above and then below the

horizon. Remember that in turns to the right, torque and slipstream effect must be offset with a

greater amount of rudder input than in turns to the left. Proper performance of the maneuver

demands smooth coordination of control pressures to maintain balanced flight. The rate of pitch

and roll during the Wingover is relatively slow, therefore the resultant increased G-loading is

relatively slight. It should not be necessary to exceed 2.0 Gs at any time during the maneuver.

Procedures

CONFIGURATION: Transition to aerobatic cruise. CHECKLIST: Complete the

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

on or parallel to a section line. Pick a prominent reference point on the horizon 90 to

either side of the nose, in the direction you intend to perform the maneuver.

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 maneuver by smoothly

raising the nose while keeping the wings level. As the exhaust stacks pass the

horizon, start a roll towards the 90 checkpoint. Control the pitch and roll rate so as

to reach 45 nose up and 45 AOB simultaneously. The aircraft's heading should also

have changed approximately 45 at this point.

Continue to roll towards 90 AOB as the nose inscribes an arcing path downward

towards the horizon. Maintain orientation by concentrating on your outside reference

points. Control the pitch and roll rate so as to arrive at 90 AOB with the nose

aligned with the 90 reference point. Airspeed should be approximately 90 KIAS at

this point. Do not exceed 90 AOB.
