Pressurisation

Question 1

During takeoff the normal outflow valve begins to meter when the:

• Power levers are set to climb.
• Bleed switches are turned on.
• PSEU is in the flight mode.
• Power levers are set 15° approx. above flight idle.

Answer 1

• Power levers are set 15° approx. above flight idle.

Question 2

The maximum normal cabin pressure differential is:

• 4.2 +/- 0.3psi
• 5.8 +/- 0.15psi
• 5.95 +/- 0.15psi
• 5.5 +/- 0.3psi

Answer 2

• 5.5 +/- 0.3psi

Question 3

The Forward Outflow valve:

• Requires no electrical supply but needs bleed air to function.
• Requires no electrical supply and no bleed air to function.
• Requires an electrical supply but no bleed air to function.
• Requires both electrical supply and bleed air to function.

Answer 3

• Requires no electrical supply and no bleed air to function.

Question 4

The maximum possible cabin / atmosphere differential pressure is:

• 5.95 psi
• 5.8 psi
• 5.5 psi
• .17 psi

Answer 4

• 5.95 psi

Question 5

The touchdown depressurisation mode is operational in:

• AUTO/CAB SET mode.
• MAN mode
• AUTO/CAB SET & AUTO/NORM mode.
• AUTO/NORM mode.

Answer 5

AUTO/CAB SET & AUTO/NORM mode.
