GENERAL - GENERAL
Applicable to:
Each powerplant has a FADEC (Full Authority Digital Engine Control) system.
FADEC, also called the electronic control unit (ECU), is a digital control system that performs
complete engine management.
FADEC has two-channel redundancy, with one channel active and one standby.
If one channel fails, the other automatically takes control.
The system has a magnetic alternator for an internal power source.
FADEC is mounted on the fan case.
The engine interface unit (EIU) transmits the data it uses for engine management to the FADEC.
