PRIMARY FUNCTIONS
The FADEC system consists of sub-systems working together to form a close
loop control system, maintaining efficient engine operation at a selected
condition ranging from engine start to engine shut-down.
The EEC primary functions are :
To start and shut down the engine, to control fuel flow and core engine air
flow, to control EPR in forward thrust and N1 in reverse mode, to control the
operation of the thrust reverser, to isolate failures and to continue to operate
so that failures have no effect.
