• inflow valve(s), pressure controller(s), control panel, pressure relief valve(s), positive relief valve(s) an monitoring devices.

• outflow valve(s), pressure controller(s), control panel, pressure combination valve(s), positive relief valve(s) an monitoring devices.

• outflow valve(s), pressure controller(s), control panel, pressure combination valve(s), negative relief valve(s) an monitoring devices.

What are the different types of outflow valves?

• automatic and pneumatic

• electrical and pneumatic

• electrical and automatic

• automatic and kinematic

What is the definition of pneumatic-actuated outflow valve?

• actuated by control pressure from a kinematic cabin pressure controller and normally spring-loaded closed and opens in responds to the applied negative control pressure.

• actuated by control pressure from a pneumatic cabin pressure controller and normally spring-loaded closed and opens in responds to the applied positive control pressure.

• actuated by control pressure from a pneumatic cabin pressure controller and normally spring-loaded closed and opens in responds to the applied negative control pressure.

• actuated by control pressure from a kinematic cabin pressure controller and normally spring-loaded closed and opens in responds to the applied positive control pressure.

On Digital Pressurization Control System, what mode is used when operating in normal operation?

• normal mode

• safety mode

• positive mode

• automatic mode

What type of control system that have four modes with a manually controlled rate of change in STBY

• digital pressurization control system

• normal de-pressurization control system

• ambient pressurization control system

• analogue pressurization control system

What will happen when the cabin altitude exceed it's normal limit?

• Aircraft will descend automatically

• Ram air inlet will open

• Bleed flow will be switched to high

• Alt Horn will sound

How is the pressurization condition in an aircraft after touchdown?

• Negative pressure inside the cabin

• Neutral Pressure inside the cabin

• Positive Pressure inside the cabin

• No Pressure inside the cabin

What is the difference between AUTO system and ALTN system in a Digital Cabin Pressure Control System?

• No functional difference

• ALTN uses set cabin altitude

• AUTO uses set pressure difference

• ALTN uses manual valve opening

What would happen to the cabin pressure when the aircraft is set for takeoff?

• The plane would pressurise

• The plane would depressurise

• The plane will close all inlet valve

• The plane will open all outflow valve

When the pressure outside the aircraft is greater than the pressure in the cabin, which valve assists the outflow valve?

• Negative Cabin Relief Valve

• Positive cabin relief valve

• neutral cabin relief valve

• non return valve
