(d)
Climb back to altitude where PA
was noted and record following:
1 Free Air Temperature.
2 Fuel Quantity.
(7) Record Previously noted: RRPM, PA,
Pedal Separation, Unusual Vibrations
(as applicable).
(8) Compare data to chart in Section V for
proper RRPM. Ensure conversion from
PA and FAT to DA.
b.
714A Autorotation RRPM Check.
(1) Stabilize airspeed at 755 kts.
(2) THRUST CONT lever — Reduce to
ground detent. Check RRPM stabilized.
(3) Simultaneously reduce thrust to full
down while placing the FADEC NR%
rheostat to 97% position.
NOTE
Rotor RPM must be at 98% or higher. If it is not at
or above 98% the pitch change links must be
adjusted.
(4) When in stabilized autorotation with
thrust full THRUST CONT — Record
the following data. (Refer to Section V.)
