11 Questions
What is the function of the re-circulation system in the aircraft air supply system?
Cleans used air and sends it back to the air supply system for distribution
What is the main function of the electronic-flight-display ventilation system?
Replaces the hot air in EFD housings with cool air
What is the source of the air supplied to the internal compartments of the aircraft?
Air-conditioning packs
Where does the air supply system get the air from for distribution?
The air-conditioning units of the cooling system
What is the function of the plenum chamber in the air supply system?
To direct airflow from the air-conditioning units to the internal compartments of the aircraft
What is the purpose of connecting the plenum chamber to the LH and RH air-conditioning units?
To ensure correct airflow directions into the flight compartment and cabin
What happens if there is a failure of the air-conditioning units in supplying pressurized air?
The ambient air inlet supplies unpressurized air from the atmosphere
Which sub-systems does the plenum chamber send air to as part of the air supply system?
The flight-compartment distribution system and cabin distribution system
What is the role of the ground-connection and ambient air inlet connections to the plenum chamber?
To supply unpressurized air in case of air-conditioning unit failure
What does the plenum chamber outlet to the flight-compartment system do?
Provides pressurized air to operate flight controls
How does the plenum chamber ensure that LH and RH air-conditioning unit airflows have correct directions before entering internal compartments?
By connecting to LH and RH air-conditioning units and directing airflow
