10 It takes complete control of ENGINE SYSTEMS in response tocommand inputs from the aircraft. It also providesinformation to the aircraft for flight deck indications, ENGINE condition monitoring, maintenance reporting It performs fuel control and provides limit protectionsfor N1 and It controls the ENGINE start sequence and preventsthe ENGINE from exceeding starting EGT limits(ai)
