Also known as Airliner APU PW901A/C

PW901C APU is a twoshaft gas turbine engine, originally derived from a Pratt & Whitney turbofan engine used in popular business jets. It provides power for the Boeing 747-8 and its predecessor, the PW901A-powered Boeing 747-400. During on-ground operation, it provides bleed air for cabin conditioning from a low spool-driven load compressor, and electrical power from two gearbox-mounted 90kVA generators.
