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 A400M aircraft at Seville Spain on 9 May 2015. Airbus Chief ...
This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
For an aircraft equipped with a constant speed propeller, this is the most direct indication of the engine's operating power. A fully open throttle would show a manifold pressure roughly equal to the ambient air pressure, i.e. full power; note that the maximum therefore changes with altitude unless the engine is equipped with a turbocharger or ...
Every single pilot flying commercial airplane has handled dozens of engine fires and failures throughout their career. So it's not new to them. They've done it dozens of times in the simulator.
Target-type thrust reversal is commonly applied to low bypass turbofan engines or turbojet engines. In this kind of engine with low bypass ratio, the core part of the engine produces a significantly larger part of the thrust. Therefore, the airflow from the core part must be blocked in order to produce sufficient reverse thrust. [10]
The PSSA may contain qualitative FTA, which can be used to identify systems requiring redundancy so that catastrophic events do not result from a single failure (or dual failure where one is latent). A fault tree is prepared for each SFHA hazard rated hazardous or catastrophic. Fault trees may be performed for major hazards if warranted.
