WARNING:
All procedures are GENERALIZED.
Fly the maneuver in accordance with the Pilot Operating Handbook (POH)
and/or current Standard Operating Procedures (SOPs)

Stall/Aerobatic Checklist:

• Cockpit: Clear of lose objects
• Seat Belts: Locked and tight
• Autoignition/Fuel Pump: On
• Engine Instruments: Checked
• Report: Stall/aerobatic checklist complete

Additional Considerations:

• Ensure pockets are zipped and the map-case is secured to prevent loose items from going airborne

T-34C PROCEDURE:

1. Give an instrument, gas, and position report (IGP)
2. CONFIGURATION: aerobatic cruise
3. Complete the stall/aerobatic checklist
4. CODES: 4700
5. Perform a clearing turn
   • Successive wingovers, when continued without interruption, serve as clearing turns for the next series
   • Roll out on or parallel to a section line
   • Anticipate the section line to roll out on it vs. searching after your clearing turn
   • Pick a reference point on the horizon, 90° to either side of the nose, in the direction you intend to perform the maneuver
6. Recheck the wings level and clear the airspace above you
   • ICS: "Entry altitude is..."
7. Raise the exhaust stacks to the horizon and then start a roll towards the 90° checkpoint
8. Control pitch and roll rate so as to reach:
   • Nose: 45° up (aggressive at first)
   • AoB: 45° ("Feels" like you need to put a lot more pitch input than AoB)
   • Heading change: 45°
9. Continue to roll towards:
   • Speed: 90 KIAS
   • AoB: 90°
   • Heading change: 90° (do not exceed 90° AoB)
10. Allow the nose to fall through the horizon, and then commence the recovery by smoothly rolling and pulling out of the diving turn
    • The tendency is to recover AoB too fast, keep it slow
11. After approximately 135 of turn:
    • Nose: 45° down
    • AoB: 45°

    • 

    • 

12. Control the pitch and roll rate so as to recover on the original altitude and reciprocal heading
    • NOTE: When the maneuver is completed at the same altitude it was initiated, there is a tendency to gain about 10 KIAS
13. Repeat steps 6 through 8, performing the second wingover in the opposite direction
    • Upon completion of the series, the aircraft should once again be established in level balanced flight, on the original heading and altitude

Wingover Common Errors:

• Failure to adequately clear the area

Airman Certification Standards:

• Airman Certification Standards

Conclusion:

• Remain mindful that performance calculations are usually more optimistic than performance in reality
• Consider actual versus realized performance when doing any performance calculations
• Consider practicing maneuvers on a flight simulator to introduce yourself to maneuvers or knock off rust
