The FADEC system is considered part of the engine, however, for reliability reasons
the FADEC units are located in the compartment inside the pressure vessel.
Each engine has two FADEC cards, either of which can control the engine. Each set
of two FADEC cards is co-located with an ACS in one of the aircraft’s two Avio
Processing Centers (APC). The FADEC cards are physically separated. The left Avio
Processing Center houses one FADEC card from each of the left and right engines.
The right Avio Processing Center also houses one FADEC card from each of the left
and right engines.
FADEC POWER SOURCES
Each FADEC unit has three power sources:
Left generator
Right generator
System battery
