-PROCEDURE:
1.
Maintain
heading

attitude.
2.
Collective
-
Adjust
to control
rate
of
descent
and
cushion
landing.
It is recommended
that
level touchdown
be made prior to
passing
through
70%

*PROCEDURE:
1.
Maintain
heading
and

control.
NOTE
ROTOR
RPM maintained
at high
end
of
operating
range
will
provide
maximum
rotor
energy
to
accomplish
landing,
but
will
cause
an
increased
rate
of
descent
2.
Collective
-
Adjust
as required
to maintain
90 to 107%
ROTOR
RPM.

COLLECTIVE
IS
FULLY
DOWN
AND
ROTOR
DECAY HAS CEASED.
NOTE
Maximum
AIRSPEED
for
steady
autorotation
is 100 KIAS
(115
MPH).
Autorotation
above
this
speed
results
in high
rates
of
descent
and low ROTOR
RPM. A
blue
radial
is installed
on the
AIRSPEED
indicator
as a reminder
of this condition.
AIRSPEED
for
Minimum
Rate
of
Descent
is 52 KIAS
(60 MPH).
AIRSPEED
for
Maximum
Glide
Distance
is 69 KIAS
(60 MPH).
Nominal
autorotative
AIRSPEED
is
61 KIAS (70 MPH).
