4-10. PRACTICE AUTOROTATIONS (cont)
Conduct practice autorotation at 94KIAS or below (see V
NE
plac-
ards). Maintain rotor between 410 and 504 by use of the collective
control.
Maximum gliding distance is obtained at 77 KIAS and 410 rotor
RPM.
Minimum rate of descent is obtained at 46 KIAS and 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

needles joined).
At a height of approximately 65 FT above the ground flare to a
nose-up attitude.
At approximately 10 feet, coordinate collective pitch with forward
movement of cyclic stick to level A/C and cushion landing make
ground contact with ship level.
