8.5 System Description
8.5.1 Full Authority Digital Engine Controller (FADEC)
The engines are controlled through two FADEC units. The FADEC has full authority
over the operation of the engine. The FADEC sets thrust by controlling fuel flow
based on throttle position. Throttle position measured by potentiometers correlates
to the desired engine power. There are three primary operating ranges for the
throttles, Idle, Maximum Continuous Thrust (MCT) and Takeoff.
