>ENGINE FAILURE AND AUTOROTATION
>
> NOTE
>Rotor RPM maintained at the high end of the
>operating range will provide maximum rotor
>energy to accomplish the landing.
>
>Collective pitch control - Adjust as required to maintain rotor
>RPM, 90% to 107%.
>
> NOTE
>Avoid large forward cyclic inputs until
>collective is full down and rotor decay has ceased.
>
>Cyclic control - Adjust to obtain desired autorotative airspeed for
>existing conditions. Normal autorotation airspeed is 70 MPH (61
>knots) IAS.
>AIRSPEED for Minimum Rate of Descent is 60 MPH (52 knots)
>IAS.
>AIRSPEED for Maximum Glide Distance is 80 MPH (69 knots)
>IAS.
>Maximum airspeed for steady autorotation is 115 MPH (100
>knots) IAS. Autorotation above this speed results in high rates of
>descent and low rotor speed. A blue radial is installed on the
>airspeed indicator as a reminder of this condition.
>If ample altitude remains, attempt Engine Air start.
>At low altitude, close throttle and flare to lose excessive airspeed.
>Apply collective pitch as flare effect decreases to further
>reduce forward speed and cushion landing. It is recommended
>that level touchdown be made prior to passing through 70%
>rotor RPM. Upon ground contact, collective pitch shall be
>reduced smoothly while maintaining cyclic in neutral or
>centered position.
>
> NOTE
>Excessive ground run with collective up, or
>any tendency to float for long distance prior
>to ground contact should be avoided. >
