A320 Family APU
© AIRBUS S.A.S. All rights reserved. Confidential and proprietary document.
The Auxiliary Power Unit (APU) provides:
Electrical power on ground and in flight
Bleed air to the pneumatic system for engine start and / or cabin control
Free park-group ground operations capability
In flight relight capability
The A320 Family provides competition for the APU. Three APUs are available:
Honeywell GTCP36-300A (standard)
APIC APS 3200 (standard option)
Honeywell GTCP131-9A (standard option).
Commonality and interchangeability
A321 APU standard can be used without conversion on A320, A319 or A318 and vice versa.
APIC and Honeywell APUs, including their ECBs, are interchangeable on A318/A319/A320/A321.
APU change does not require modification of any other system (Drop-In interchangeability).
Total modification is contained within the APU/ECB system.
The Honeywell APU 131-9A is Drop-In equipment for the A318/A319/A320/A321 with no change to the aircraft structure.
