INTRODUCTION
It is very easy to find actual manuals for the A320 range of aircraft on the internet. For obvious reasons we cannot
include them but even a quick source will lead you to a treasure-trove of information. Start your search with
‘A320 FCOM’ to find complete operation manuals. Almost all you find in there is applicable to this product.
AIRCRAFT GENERAL
The Airbus A320 family includes the A318, A319, A320, and A321, all medium range, subsonic narrow body civil
aviation aircraft. Powered by two high-powered by-pass turbofan engines they seat up to 220 passengers.
AIR CONDITIONING & PNEUMATICS
The air conditioning system is fully automatic and provides continuous renewal of conditioned air in three zones:
COCKPIT, FWD CABIN and AFT CABIN. Temperatures in these three zones can be regulated independently. The air
is supplied via the pneumatic systems using:
 two pack flow control valves
 two packs
 the mixing unit that combines air from the packs and the cabin
The cold air from the PACKs is mixed with the hot bleed air (taken from the engines or APU) by a mixing unit that
is controlled by the zone regulator.
All control is done via the AIR COND panel on the overhead panel.
 Zone temperature control selectors
o COLD = 18 °C
o CENTER = 24 °C
o HOT = 30° C
 HOT AIR pb switch
o ON: hot air pressure is regulated
