PRESSURIZATION

Question 1

PRESSURIZATION

1. The pressurization controller uses data from
   DADC #__, and reverts to _______ mode
   when air data is not available. Manual
   pressurization control is available through
   the _______ ______ ______ on the tilt panel.

Answer 1

PRESSURIZATION

1. The pressurization controller uses data from
   DADC #1, and reverts to Isobaric mode
   when air data is not available. Manual
   pressurization control is available through
   the manual toggle valve on the tilt panel.

Question 2

PRESSURIZATION

2. The pressurization controller schedules
   cabin altitude based on ______ _____ _______
   (from the DADC), current ______ ______
   (also from the DADC), and _______ _____
   ________ (from the elevation set by the pilot
   on the pressurization controller.)

Answer 2

PRESSURIZATION

2. The pressurization controller schedules
   cabin altitude based on takeoff field elevation
   (from the DADC), current flight altitude
   (also from the DADC), and destination field
   elevation (from the elevation set by the pilot
   on the pressurization controller.)

Question 3

PRESSURIZATION

3. Pressurization is normally maintained by
   a continuous supply of ________ ______
   ___ and ______ _______. The outflow is
   regulated by the _________ ________
   via the ______ ______.

Answer 3

PRESSURIZATION

3. Pressurization is normally maintained by
   a continuous supply of conditioned bleed
   air and regulated outflow. The outflow is
   regulated by the pressurization controller
   via the outflow valves.

Question 4

PRESSURIZATION

4. The CABIN DUMP switch is _______
   operated and commands the outflow valves
   to open. With the DUMP switch _______,
   maximum cabin altitude is limited by the
   mechanical cabin altitude limit valves
   installed on the ______ ______.

Answer 4

PRESSURIZATION

4. The CABIN DUMP switch is electrically
   operated and commands the outflow valves
   to open. With the DUMP switch activated,
   maximum cabin altitude is limited by the
   mechanical cabin altitude limit valves
   installed on the outflow valves.

Question 5

PRESSURIZATION

5. The pre-pressurization mode of the
   pressurization system starts to pressurize the
   cabin during the ______ ____ to avoid pressure
   bumps at liftoff. This is activated when the
   throttles are advanced above approximately
   ___% N2.

Answer 5

PRESSURIZATION

5. The pre-pressurization mode of the
   pressurization system starts to pressurize the
   cabin during the takeoff roll to avoid pressure
   bumps at liftoff. This is activated when the
   throttles are advanced above approximately
   85% N2.

Question 6

PRESSURIZATION

6. The emergency pressurization function
   supplies extra bleed air to the cabin through
   the ________ ____-___ system.

Answer 6

PRESSURIZATION

6. The emergency pressurization function
   supplies extra bleed air to the cabin through
   the windshield anti-ice system.
