Air Conditioning and Pressurization System

Question 1

What systems are deactivated when the cabin pressure switch is in the RAM DUMP position?

Answer 1

• Canopy defog
• Cabin pressurization and air-conditioning
• Canopy seal
• Anti-G suit

Question 2

Compute the normal cabin pressure altitude: 8,000 ft

Answer 2

8,000 +- 1,000

Question 3

Compute the normal cabin pressure altitude: 31,000 ft

Answer 3

12,500 +- 2,000

Question 4

Compute the normal cabin pressure altitude: 35,000 ft

Answer 4

14,500 +- 2,000

Question 5

Compute the normal cabin pressure altitude: 40,000 ft

Answer 5

17,000 +- 2,000

Question 6

The canopy defog control affects the

Answer 6

Volume of the defog air

Question 7

Assuming you have complete AC power failure, how will the air conditioning and pressurization system be effected?

Answer 7

• You cannot change the ram dump valve position

- You cannot control the temperature of the cabin air

Question 8

How is ice removed from the air-conditioning system?

Answer 8

A de-ice control valve opens automatically when ice forms in the air-conditioning system, allowing hot air to pass through the moisture separator where the ice has formed

Question 9

How do you eliminate smoke and fumes from the cockpit?

Answer 9

RAM DUMP (below 25,000 feet if possible)

Question 10

You have just started a go-around when you hear a loud fluttering noise. This is the pressure relief valve in the moisture separator. What would you do to prove that the noise is from the relief valve and not from an engine compressor stall?

Answer 10

Check engine instruments for normal indications. Increase temperature on the temperature control to stop the fluttering of the temperature control valve

Question 11

How can you help prevent the canopy from fogging up during a descent from high altitude?

Answer 11

Blow all the moisture out of the system at low altitude by turning the cabin temperature controls to the full hot position. Prior to descent, preheat the canopy using the canopy defog

Question 12

Cabin temperature and canopy defog controls are powered how?

Answer 12

AC electrically and pneumatically powered

Question 13

The cabin pressurization and air-conditioning controls are located in which cockpit?

Answer 13

The front cockpit

Question 14

What will occur in the cockpit concerning the air-conditioning and pressurization system with dual-generator failure?

Answer 14

Everything remains as it is except you cannot ram dump or change the cabin temperature

Question 15

Below what altitudes must you descend for oxygen and pressure failure?

Answer 15

10,000 feet cabin pressure altitude and 25,000 feet cabin pressure altitude respectively
