9. PRACTICE AUTOROTATION
WARNING
Perform throttle rigging check prior to attempting practice
autorotations. (See Engine Run
−
up).
Misrigging of the throttle control may result in inadvertent
flameout during rapid closing of the twistgrip to the ground idle
position.
Do not practice autorotation if FUEL LOW caution indicator light is illumi-
nated. If while in practice autorotation, FUEL LOW caution indicator lights,
return to powered flight.
Make practice autorotation landings as follows:
For autorotation descent, the twistgrip should be in the full open or ground
idle position. However, if a practice autorotation landing (minimum engine
power) is desired, rotate the twistgrip to the ground idle position.
NOTE
:
Increase collective pitch after establishing autorotation to prevent rotor
overspeed if flight is being conducted at high gross weight or high density
altitude. To reduce rate of descent or to extend gliding distance, operate at
minimum rotor rpm. Restore rotor rpm by lowering collective prior to flareout.
If a power recovery is desired, lower collective to full down, rotate the twist-
grip to the full open position, verify that N
2
is between 103 and 104 percent
and that full engine power is available prior to increasing collective.
Maintain rotor between 400 and 514/523 (observe rotor limits on rotor tach) by
use of the collective control.

range”.
Maximum gliding distance is obtained at 80 knots and 400 rotor rpm.
Minimum rate of descent is obtained at 60 knots and 400 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

Touchdown in a level attitude.
Avoid use of aft cyclic control or rapid lowering of collective pitch during initial
ground contact or during ground slide.
