Full Authority Digital Electronic Control of Pratt and Whitney 305 Turbofan Engine

In the present competitive aerospace industry, there is an increased demand on performance and safe operation of the propulsion system in particular for commuter and business aircrafts. Pratt and Whitney Canada has developed the PW305 turbofan engine equipped with a Full Authority Digital Electronic Control (FADEC) to meet these demands. The control system is designed to provide optimum engine operation within safe limits, reduced pilot workload and high reliability over the whole flight envelope. This paper gives a general overview of the requirements, development, operability and performance of the PW305 propulsion system.
