The FADEC System – Electronic Control Unit (ECU)

A full authority digital engine or electronics fadfc FADEC is a system consisting of a digital favec, called an “electronic engine controller” EEC or ” engine control unit ” ECUand its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines.

The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine.

By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. Analog electronic control varies an electrical signal to communicate the desired engine settings.

The system was an evident improvement over mechanical control but had its drawbacks, including common electronic noise interference and reliability issues. Digital electronic control followed. In Rolls-Royce and Elliott Automationin conjunction with the National Gas Turbine Establishmentworked on a digital engine control system that completed several hundred hours of operation on a Rolls-Royce Olympus Mk True full authority digital engine controls have no form of manual override available, placing full authority over the operating parameters of the engine in the hands of the computer.


If the engine is controlled digitally and electronically but allows for manual override, it is considered solely an EEC or ECU.

When standing alone, the EEC makes all of the decisions until the pilot wishes to intervene. FADEC works by receiving multiple input variables of the current flight condition including air densitythrottle lever position, engine eccu, engine pressures, and many other parameters. The inputs are received by the EEC and analyzed up to 70 times per second. Faeec operating parameters such as fuel flow, stator vane position, air bleed valve position, and others are computed from this data and applied as appropriate.

FADEC also controls engine faxec and restarting. FADEC not only provides for efficient engine operation, it also allows the manufacturer to program engine limitations and receive engine health and maintenance reports.

For example, to avoid exceeding a certain engine temperature, the FADEC can be programmed to automatically take the necessary measures without pilot intervention.

With the operation of the engines so heavily relying on automation, safety is a great concern. Redundancy is provided in the form of two or more separate but identical digital channels.

Each channel may provide all engine functions without restriction. FADEC also monitors a variety of data coming from the engine subsystems and related aircraft systems, providing for fault tolerant engine control. Engine control problems simultaneously causing loss of thrust on up to three engines have been cited as causal in the crash of an Airbus AM ech at Seville Spain on 9 May Airbus Chief Strategy Officer Marwan Lahoud confirmed on 29 May that incorrectly installed engine control software caused the fatal crash.

The flight crew first enters flight data such as wind conditions, runway length, or cruise altitude, into the flight management system FMS. The FMS uses this data to calculate power settings for different phases of the flight. At takeoff, the flight crew advances the throttle to a predetermined setting, or opts for an auto-throttle takeoff if available. The FADECs now apply the calculated takeoff thrust setting by sending an electronic signal to the engines; there is no direct linkage to open fuel flow.


This procedure can be repeated for any other phase of flight. In flight, small changes in operation are constantly made to maintain efficiency.
