CRUISE
Refer to Figure 3 for a Flight Profile of Climb, Cruise, and Descent.
The maximum cruising speed is limited by V
MO
, M
MO
, or maximum cruise rating.
The recommended Intermediate cruising speed is:
•
280 KIAS up to 29,000 ft.
•
0.75 M
IND
at 31,000 ft and above.
The recommended Long Range cruising speed is:
•
230 KIAS up to 35,000 ft.
•
220 KIAS at 37,000 ft.
•
0.70 M
IND
at 39,000 ft and above.
Section IV - FLIGHT PLANNING DATA contains performance data related to the above procedures.
Thrust should be adjusted as required to achieve these speeds and any thrust setting up to maximum
recommended cruise thrust may be used.
On most occasions, N
1
RPM will be the operating restriction and should be periodically checked and
reset if necessary, especially after a change of altitude or Indicated Outside Air Temperature (IOAT).
Where the highest practicable cruising altitude is required, the cruise may be started at a speed below
220 KIAS or 0.70 M
IND
and the airplane may be allowed to accelerate as weight decreases, maintaining
maximum cruising thrust until the desired speed is reached.
Section IV - FLIGHT PLANNING DATA gives the maximum cruising altitude against weight and
temperature, together with the IAS on which they are based.
These speeds are the lowest at which the airplane will cruise comfortably and no attempt should be
made to cruise slower.
MANEUVERING AT HIGH ALTITUDES
Refer to the Airplane Flight Manual, Section 2, Limitations.
At Mach numbers greater than about 0.7, the buffet onset boundary is defined by an agitation of the
ailerons which can be felt through the control column.
At lower Mach numbers, the boundary is defined by airframe buffet.
STABILITY AND TRIM CHANGE
Small amplitude dutch roll may occur and can be easily corrected by small aileron movements or, more
effectively, by the use of the yaw damper.
NOTE:
The yaw damper also increases directional stability during turbulence.
Changes of trim with power, landing gear, and airbrakes are small. There is a nose down change of trim
as the flaps are extended, becoming distinctive beyond 25°.
