Many modern aircraft use single-lever power control (SLPC) system, where on-board computer automatically manages the propeller speed based on the desired power setting and operational conditions. The output power from the propeller is equal to a product of propeller efficiency and input power from the engine.
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.
Aero Engine Controls is the former name of Rolls-Royce Controls and Data Services. The company produces engine control software, electronic engine controls (EEC) , fuel metering units (FMU) , fuel pumps and engine actuators for a large number of common commercial and military aircraft. [ 1 ]
An engine-indicating and crew-alerting system (EICAS) [1] is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist.
It produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1] Together these parts comprise the control system for a jet engine, responsible for delivering the correct amount of fuel and maintaining engine safety.
The damage to the 727's right wing control surfaces and control system hydraulics made the aircraft uncontrollable. All 135 people aboard the 727, both pilots in the Cessna, and 7 people on the ground were killed, for a total of 144 fatalities. Aeroméxico Flight 498, August 25, 1986, McDonnell Douglas DC-9.
The fuel must be reduced with altitude to maintain the same a/f ratio as the lower ambient pressure means less weight of air entering the engine (early engine controls used a Barostat or Barometric Pressure Control depending on the type of fuel pump, fixed or variable displacement). [20]
[6] China Northwest Airlines Flight 2303 lost control during take-off from Xi'an, China. The aircraft, a Tupolev Tu-154, had had maintenance carried out before its flight, and the autopilot yaw channel had been erroneously connected to the bank control, and vice versa. Additionally, this incorrect maintenance was not done in a properly approved ...
