Full Authority Digital electronic Control (FADEC)
The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. The complexity of this task is proportional to the complexity of the engine. The history of full authority digital electronic control FADEC started in the 1960’s when Rolls Royce experimented with their Olympus 593 engine on a Concorde. The start of full authority digital electronic control (FADEC) was a full authority analogue control and was the first used on Rolls Royce’s Olympus 593 afterburning turbojet, the first to be used in commercial flight in 1964. Following analog electronic control, the logical progression was to digital electronic control systems. In the 1970’s NASA worked with Pratt and Whitney with their TF30 as their experimental engine on an f-111. The first engines to respectively use dual full authority digital electronic control FADEC were the PW4000. Smiths Industries Controls developed (FADEC). The purpose of the full authority digital electronic control (FADEC) system is to have no form of manual override available and have everything controlled by computer. The past systems have relied on flight crew to monitor and adjust parameters ensuring safe flight and engine health over time. During this paper it will show that the Full authority digital electronic control (FADEC) has improved safety of flight along with breaking technology that is continuously enabling pilots to focus more on the flying and less on the parameters of the engines. The technologies and research by Nasa proved to be one of the most innovative break through in todays turbine engines and are continuing to do research by monitoring the health of engines with the full authority digital electronic control (FADEC) system

The difference between that full authority digital electronic control full authority digital electronic control (FADEC) system and later electronic engine...
