- Reverse of an immelmann
- Combining the first half of an aileron roll with the last half of a loop
- Provides a rapid reversal of heading
- To minimize loss of altitude, it is very important that you immediately pull and maintain optimum AoA after rolling inverted until 4.0-Gs
- Cockpit: Clear of lose objects
- Seat Belts: Locked and tight
- Autoignition/Fuel Pump: On
- Engine Instruments: Checked
- Report: Stall/aerobatic checklist complete
- Ensure pockets are zipped and the map-case is secured to prevent loose items from going airborne
- Give an instrument, gas, and position report (IGP)
- CONFIGURATION: aerobatic cruise
- Complete the stall/aerobatic checklist
- CODES: 4700
- Perform a clearing turn
- Roll out of the clearing turn on or parallel to a section line
- Anticipate the section line to roll out on it vs. searching after your clearing turn
- IDLE: Reduce power to idle and maintain altitude, while slowing to 130 KIAS
- Increase right rudder pressure as the aircraft decelerates
- STACKS: At 130 knots, raise the nose to place the exhaust stacks on the horizon, while keeping the wings level
- RELAX: Stop nose movement by relaxing back stick pressure
- RUDDER: direction of roll
- Rudder application will be light or it will kick the tail out
- ROLL: lateral stick deflection in the direction of roll
- Once inverted, neutralize the ailerons and apply slight forward stick pressure to momentarily maintain straight and level flight
- Quickly verify that the wings are level by referencing the horizon and correct as necessary
- Apply back stick pressure, pulling the nose through the horizon and flying the aircraft along the section line as in the last half of the loop
- Expect 1,500' loss of altitude
- Decrease right rudder pressure as the aircraft accelerates to recovery speed
- ICS: "Oil pressure is..." (checking within limits)
- Reset aerobatic cruise power
- Failure to adequately clear the area
- Pulling too hard for the first 90° or not hard enough, when transitioning from the AoA to G
