pressurization Flashcards
Automatic transfer of the pressurization controllers occurs after ____ or in case of failure of the ___ controller
landing,
operating
Before takeoff and after landing, the outflow valve should be ____ and the cabin _____
OPEN
Depressurized
The autmomatic pressurization controller normally uses landing eleveation QNH from the
FMGC
during descent the cabin pressure is controlled so that
it reaches landing field pressure just prior to landing
how is the landing field elevation provided to the pressurization system in the case of a divert to an alternate?
The FMGC provides database elevation when a new destination is entered
if the airplane returns to the departure airport immediately after the after takeoff, how is the cabin altitude controlled?
Cabin altiutude automatically returns to the takeoff elevation
how is the cabin altitude controlled when in the manual mode?
by toggling the MAN V/S CTL switch
in case of failure of both pressurization controllers, a third motor provides
Manual operation of the outflow valve
illumination of the MODE SEL FAULT light indicates
A fault is detected in both automatic systems
The cabin safety valve protects against
Excessive differential pressure
What elevation is set on the LDG ELEV selector?
500 ft
whan landing elevation is selected with the LDG ELV selector, the cabin altitude is
still controlled automatically through the outflow valve
how is the pressurization system controlled manually
Selecting MODE SEL switch to MAN and using the MAN V/S CTL switch to control the outflow valve
