How does a FADEC work?

FADEC combines throttle, prop, and mixture controls into a single control. Every throttle setting at any altitude results in the optimum power/prop RPM/mixture combination. This enables pilots to realize fuel economy that would only have been dreamed of previously.

What is the function of FADEC?

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 does the FADEC use to supply information to the EEC?

FADEC Fuel Control Systems The system uses electronic sensors that feed engine parameter information into the EEC. The EEC gathers the needed information to determine the amount of fuel flow and transmits it to a fuel metering valve.

What happens to an airplane when the engine fails?

With the remaining engine already generating maximum power, the only way to keep the speed up is to descend. At this stage, the Flight Management Computer will have detected the engine failure scenario and will display the altitude at which the aircraft will be able to keep its airspeed at a safe value.

Why do pilots have to turn off their track before descending?

In order to avoid this conflict, before the aircraft starts to descend the pilots must turn the aircraft off their assigned track. As mentioned before, it can take a minute or two for the aircraft to start descending, so pilots have some time to make this turn.

Are flight crews prepared to diagnose turbofan engine malfunctions?

However, because of the rarity of turbofan engine malfunctions, and the limitations of simulating those malfunctions, many flight crews have felt unprepared to diagnose engine malfunctions that have occurred. The purpose of this text is to provide straightforward material to give flight crews the basics of airplane engine operational theory.

How do pilots train to deal with engine problems?

Every six months, all pilots must undergo two days of checking and training in a flight simulator. This is to make sure that should a technical problem occur, we are able to deal with it in a safe and timely manner. Part of this is practicing how to deal with engine problems in various stages of flight.
