Wingover

Introduction:

  • 180° reversal in the direction of flight through the vertical
    • Combines a climbing turn for 90°, and a smooth descending turn for 90° but with a 180° heading change
  • The nose will never exceed 45° up and down or 2.0-Gs; it is very slow and gentle, developing the ability to smoothly control the aircraft in balanced flight, through constantly changing attitudes and airspeeds
  • Performed in opposing pairs
  • Can be used as a clearing turn
  • The maneuver is very slow and gentle
  • The roll rate should be constant through the maneuver
  • Note that you never exceed 45° nose up

WARNING:
All procedures here are GENERALIZED for learning.
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°
    • Wingover Maneuver

      Wingover Maneuver
  12. Control the pitch and roll rate so as to recover on the original altitude and reciprocal heading

  13. NOTE:
    When the maneuver is completed at the same altitude it was initiated, there is a tendency to gain about 10 KIAS

  14. 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

Conclusion:

  • Consider practicing maneuvers on a flight simulator to introduce yourself to maneuvers or knock off rust
