Purpose: A coordinated maneuver to demonstrate a condition when a rapid decrease in forward airspeed is required (aborted takeoff), ending with bringing the helicopter to a hover.
|Cyclic:||Pitch Attitude/Airspeed; Ground Track|
|Collective:||Altitude; Rate of Descent|
|Pedals||Trim (Deceleration); Heading (Descent)|
- Achieve a normal takeoff profile into the wind following the height/velocity curve.
- Begin the stop by smoothly lowering the collective while simultaneously applying aft cyclic and right pedal.
- Apply aft cyclic and additionly decreased collective as needed to maintain the entry altitude.
- To avoid ballooning, increase the amount of down collective and/or use less aggressive aft cyclic.
- As airspeed is lost, the aircraft will begin to settle. Slowly being to increase the collective to control the rate of descent. Add forward cyclic to level the aircraft when slowing to approximately ETL, while maintaining the heading with pedal.
- Terminate at a 3-5 foot hover.
Note: Use caution to avoid letting the aircraft settle with a tail low attitude! Additionally, ensure that the termination of the maneuver is not at an excessively high hover height.
