Pressurization

Question 1

True or False? The pressurization can hold a 5,000 ft cabin at the maximum certified altitude of 41,000 ft.

Answer 1

False, it holds an 8,000 ft cabin

Question 2

What is the maximum pressure differential that the cabin can hold?

Answer 2

8.6 psid

Question 3

What is the function of the cabin altitude limit valves?

Answer 3

To re-establish cabin pressure at a cabin altitude of 13,000 ft +/- 1,500 ft

Question 4

True or False? The emergency dump switch requires no DC power to function.

Answer 4

False

Question 5

The digital pressure controller will set a maximum climb rate of how many foot per minute?

Answer 5

+500 / -600 fpm

Question 6

On the ground, what will cause the airplane to go into pre-pressurization mode?

Answer 6

On the ground with both throttles about 85% N2

Question 7

Prior to takeoff, what should you set in the digital pressure controller window?

Answer 7

Destination Field Altitude

Question 8

How do you know if the digital pressure controller goes into isobaric mode?

Answer 8

1. A yellow caution light appears in the top left corner of controller display face
2. Pilot selected destination altitude will be replaced with flight level, allowing pilot to set desired cruise altitude

Question 9

If the pressurization system goes into manual mode, how would you climb and descend the cabin?

Answer 9

By moving the manual toggle switch

Question 10

How do you test the digital pressure controller prior to flight?

Answer 10

1. On the ground, engines running, door closed
2. Press and hold EXER button
   Cabin will pressurize at 100 fpm to 200 fpm below field elevation in about 2 minutes
