What is a FADEC system?
Digital Electronic Control System Full Authority Digital Engine Control (FADEC) means just that. There is no direct pilot control over the engine or manual control mode. If the FADEC fails, the engine fails.
What is FADEC system in aircraft?
FADEC is an acronym for Full Authority Digital Engine Control, a computer-managed aircraft ignition and engine control system used in modern commercial and military aircraft to control all aspects of engine performance digitally, in place of technical or analog electronic controls.
What is the function of FADEC?
The FADEC’s basic purpose is to provide optimum engine efficiency for a given flight condition. FADEC not only provides for efficient engine operation, it also allows the manufacturer to program engine limitations and receive engine health and maintenance reports.
What is the role of EEC in FADEC?
EEC or ECU is the main component of FADEC. It controls the engine actuation system depending upon the situation and the commands received from cockpit. It receives data from all the sensors, commands from cockpit. It processes the data and figures out what control commands need to be given to the actuation system and then execute them.
What does FADEC stand for in engine category?
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an “electronic engine controller” (EEC) or “engine control unit” (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines.
What happens if the FADEC fails on a plane?
Due to the high number of parameters monitored, the FADEC makes possible “Fault Tolerant Systems” (where a system can operate within required reliability and safety limitation with certain fault configurations) Upon total FADEC failure, pilots have no manual controls for engine restart, throttle, or other functions. (see note)
What are the advantages of a distributed FADEC architecture?
NASA has analyzed a distributed FADEC architecture rather than the current centralized one, specifically for helicopters. Greater flexibility and lower life cycle costs are likely advantages of distribution. ^ “Chapter 6: Aircraft Systems” (PDF).
