10. Speed Sweep Check.
Increase and stabilize airspeed at 150
a. Record longitudinal stick position.
b. Evaluate 1/REV and 3/Rev vibration.
c. Coordinated turns.
11. CYCLIC TRIM Check.
a. Observe both CYCLIC TRIM indicators
have reached the leading edge of the EXT
range 150 knots. FWD and AFT LCT
schedules corrections for increases in
pressure altitude are shown in Section V.
b. Decrease and stabilize airspeed below
extended envelope corrected for altitude
(Refer to Section V).
c. CYCLIC TRIM indicators Check both out
of EXT range.
Before entering autorotation ensure outside
area is clear, suitable forced landing area
within range and crew notified.
Autorotation above 102% RRPM will be
accompanied by an overall increase in vibration.
