NORMAL PROCEDURES
control, reset the aircraft altitude on the cabin altitude controller to 1000 feet
above the cruise altitude and adjust the cabin rate of climb as desired. The
normal 9 o'clock position should provide a cabin rate of climb of approxi-
\.,,.,1 mately 500 feet per minute. No additional adjustment should be required
prior to descent unless cruise altitude is changed, at which point the aircraft
altitude should be reset to 1000 feet above the new cruise altitude.
WARNING
Do not land with aircraft pressurized.
To descend for landing be certain that the selected cabin altitude is
higher than the pressure altitude of the landing field. Shortly after letdown is
initiated, set the cabin altitude to 1000 feet above the pressure altitude of the
landing field and adjust the rate control high enough to allow the cabin to
descend to the landing setting before the aircraft descends to that altitude.
For normal letdown the rate knob should be at the normal 9 o'clock
position. A higher setting should be selected for rapid descents so that the
aircraft altitude does not catch up with the cabin altitude.
To repressurize while in flight push the pressurization control in and
turn the dump switch OFF.
4.47 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).
