Adverse Environs Flashcards
Engine anti-ice must be turned ON during all ground and flight operations in icing conditions. The definition of icing is:
OAT is less than or equal to 10 degrees C and visible moisture.
Which of the following DOES NOT provide input to the pressurization controllers?
FADECs
The input provided by the Flight Management and Guidance Computers (FMGCs) enable the pressurization controllers to:
Know the planned cruise altitude and plan the cabin climb profile accordingly.
The following areas are not pressurized?
Radome, landing gear bays, air conditioning and tail.
The pressurization controllers use the field elevation of your destination airport to plan the descent profile. In normal operations , this information is provided how?
By the FMS database once you enter the destination airport in the MCDU
When do the two pneumatic pressurization safety valves automatically open?
They open automatically when it becomes necessary to relieve positive or negative cabin pressure.
After landing, the active and standby pressurization controllers do what?
Automatically transfer after 70 seconds.
With the pressurization in manual mode, the outflow valve is now controlled by what?
The MAN V/S control switch.
With the MODE SEL in MAN, moving the MAN V/S UP
does what? DN does what?
Opens true outflow valve and DN closes it.
The ditching push button is used to?
Close all fuselage openings below the floatation line.
On landing, cabin altitude will be?
Slightly lower than field pressure altitude.
In Ground Mode, the outflow valve will do what?
Gradually open during the landing rollout.
When is Pressurization Abort Mode activated?
If the aircraft must return to the departure airport after takeoff.
