4.39 TURBULENT AIR OPERATION

In keeping with good operating practice used in all aircraft, it is recom-

mended that when turbulent air is encountered or expected, the airspeed be

reduced to maneuvering speed to reduce the structural loads caused by gusts

and to allow for inadvertent speed build-ups which may occur as a result of

the turbulence or of distractions caused by the conditions. (See Subsection

2.3)

4.41 WEIGHT AND BALANCE

It is the responsibility of the owner and pilot to determine that the airplane

remains within the allowable weight vs. center of gravity envelope while in

flight.

For weight and balance data, refer to Section 6 (Weight and Balance).
