The passenger's comfort aboard an aircraft is provided by several features such as cabin size, seats design, noise level and mainly air quality.
From where does this
air comes from ?
How it is set to the required characteristics ?
The main process is :
- first to bleed air from the engines.
- secondly to cool this air to the suitable pressure and temperature.
- then to distribute this air to the various cabin zones at the right temperature.
- finally to control the air pressure for the passenger's comfort and aircraft safety.
These tasks are carried out by the AIRCRAFT AIR SYSTEMS which are described in the next following pages:
|TASKS||bleed the air||cool the air||distribute the air||pressure regulation|
|SYSTEM NAME||engine bleed air system||air cooling system||distribution and zone temperature control system||cabin pressure control system|
