A318/A319/A320/A321 APU
On ground, the APU makes the aircraft independent of pneumatics and electrical sources by: - Providing bleed air for engine start and air conditioning systems - Providing electrical power to supply the electrical system In flight, provision of back-up power for electrical and air conditioning systems, The APU may be started using either the aircraft batteries, external power or normal aircraft supply. APU starting is permitted throughout the APU start envelope. The APU is automatically controlled by the Electronic Control Box (ECB) which is mainly acting as FADEC for monitoring start and shut-down sequences, bleed air and speed/temperature regulation. Control and displays: - On the overhead panel for APU normal operation and fire protection - On the ECAM for APU parameters display - On the external panel, under the nose fuselage, for APU shut down.
