Low speed maneuvering:
Certain maneuvers may cause extreme T/R flapping and pounding
of the T/R teetering stop support portion of the retaining nut (felt
and heard by the pilot as a momentary medium frequency vibration).
These maneuvers usually involve rapid yaw rates that allow the
T/R to pass through the relative wind line. Maneuvers such as
simulating a T/R failure in a hover, rapid pedal turns at speeds
above translational lift, and uncoordinated agricultural type turns
may fall into this category and should be avoided.
Repeated pounding of the stop support may lead to the shearing
of the inner key on the tang washer and subsequent loosening
of the retaining nut.
Practice autorotation:
Practice autorotation should be conducted at 130 knots IAS or below (see
V
NE
placards). Maintain rotor speed between 415 and 523 RPM by use of
collective control.
Maximum gliding distance is obtained at 80 knots; 415N
R
.
Minimum rate of descent is obtained at 60 knots; 415N
R
.
Engine/aircraft shut down:
Maintain pedals in center position until rotor has stopped turning to pre-
vent excessive tail rotor flapping.
PART V
PERFORMANCE DATA
Hover performance:
IGE controllability has been demonstrated to be adequate in winds up to 17
knots from any direction − the least favorable wind azimuth, which would
have the least left pedal margin, is 45 degrees right of the nose.
Refer to Section V for IGE hover performance.
