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
Why ram air push button can be used when differential pressure is below 1 PSI?
To prevent rapid decompression of cabin
To prevent slow decompression of cabin
To prevent a rapid compression of the cabin
To prevent a slow compression of the cabin
What will happen to the differential pressure if the Ditching switch is operated on the ground and with low pressure ground cart connected?
Nothing Changes
Decrease in Delta-P
Increase in Delta-P
The cabin becomes a vacuum
Where blowout panels are located?
Landing Gear
Empennage
Cargo
Flightdeck
Which valve will operate if the outflow valve fails in the closed position, to protect the aircraft structure from excessive differential pressure?
Negative Cabin Relief Valve
Positive Cabin Relief Valve
Neutral Cabin Relief Valve
Non-Return Valve
The pressure surrounding the aircraft is called
Ambient Pressure
Gauge Pressure
Dynamic Pressure
Absolute Pressure
