TAXI OUT/BEFORE TAKEOFF
Pressurization Manual Controller ................................. FULL UP
This setting will make the cabin altitude remain stable during taxi,
independent of any variation in bleed.
Just before take-off:
Manual Controller ......................................................... 11 O’CLOCK
POSITION
This position will guarantee an acceptable pressurization during
climb out.
AFTER TAKEOFF/CLIMB
Just after the initial climb:
Pressurization Manual Controller ................................. BETWEEN 11
AND 12
O’CLOCK
Keeping the manual controller within the white mark allows a null or
slightly positive rate for the cabin altitude.
Passing 10000 ft pressure altitude:
Manual Controller .........................................................TURN
CLOCKWISE
Identify the resulting cabin rate. Usually a 400 to 500 ft/min will be
sufficient for this situation.
Above 10000 ft:
QRH Table.................................................................... CHECK
Search for the LOSS OF PRESSURIZATION INDICATION
procedure in the QRH and use the table contained therein.
Maintain the cabin altitude consistent with the airplane altitude
specified on the table by close monitoring differential pressure and
intermittent setting of the manual controller.
