Schweizer S330 - Engine Failure - Cruising at Altitudes 450 Feet and Above

3-2. ENGINE FAILURE - CRUISING AT ALTITUDES 450 FEET AND
ABOVE

Enter normal autorotation by lowering collective pitch.
NOTE:
At airspeeds above maximum autorotational V
NE
(94
knots), use aft cyclic to maintain aircraft’s attitude and to slow to
desired airspeed as collective pitch is lowered. Increase collective
as necessary after entering autorotation to prevent rotor overspeed.
Operate at minimum rotor RPM to reduce rate of descent or to
extend glide distance. Restore rotor RPM by lowering collective
prior to flare.

Select landing spot and maneuver as required.

Maximum gliding distance is obtained at 77 knots/410 rotor RPM.

Minimum rate of descent is obtained at 46 knots/410 rotor RPM.
NOTE:
Glide distances attained during an actual engine out
autorotation may be less than the glide distances achieved during
practice autorotations when operating at reduced RPM (N
2
/N
R
needles joined).

A restart may be attempted at the discretion of the pilot.

If unable to restart, turn off unnecessary switches and shut off fuel.

Flare as required for the terrain; level aircraft before ground contact.

Touch down in a level attitude.

Avoid the use of aft cyclic stick or rapid lowering of the collective
pitch during initial ground contact or during ground slide.

In the event of an engine failure at night, do not turn on the landing
light at more than 1000 feet above terrain; this conserves battery
power.
