Pressurization Flashcards
- Cabin pressurization is normally maintained by:
B. Controlling the amount of air escaping the cabin.
- Normal pressurization modes are:
D. All of the above
A. Ground taxi
B. Prepressurization during takeoff
C. Flight mode and landing mode
- When both throttles are advanced above
85% N2 on the ground:
C. The prepressurization mode is initiated
- The outflow valves are opened to reduce cabin pressure by:
D. All of the above
A. The digital AUTO controller that meters ejector vacuum to the primary outflow valve
B. The CABIN DUMP switch
C. The MANUAL switch selection and using the red knob to manually meter ambient low pressure air to the secondary valve
- The two outflow valves are closed to increase cabin pressure by:
D. Both A and B
A. AUTOMATIC control that meters service air pressure to close the primary valve
B. Selecting MANUAL and using the red knob to meter cabin air pressure to the secondary valve
- If vacuum becomes uncontrolled in flight:
C. The cabin rapidly climbs, but does not exceed 14,500 ‡ 500 feet.
- The normal mode for controlling cabin pressure is:
A. The AUTO mode
- The source of bleed air for cabin pressurization when the EMER PRESS ON annunciator is illuminated in flight is:
C. Either or both engines
- The DC powered pressure controller modes is (are):
D. Both A and B
A. The isobaric mode
B. The AUTO mode
- If the air data computer fails in flight:
A. The controller amber light illuminates and SET ALT window changes to FL isobaric mode
- Prior to takeoff, the controller is normally set to:
A. Destination elevation
- The controller continuously generates au-toschedule signals in flight, based on:
A. Departure field elevation, the maximum altitude reached, and pilot input of destination elevation.
- On the ground, with either engine operating below 85% N2:
C. Both outflow valves are open
- Operating in high altitude mode of operation:
C. Cabin altitude climbs and remains at approximately 8,000 feet while the aircraft is above 25,000 feet.
