Embodiment Construction

[0017] refer to figure 1 , the aircraft 1 comprises two engines 2 , 3 each controlled by a control unit 4 , 5 connected to an interface device 6 in order to coordinate the control of the engines 2 , 3 . The interface device 6 is itself connected to a monitoring device 7 (e.g. of the EWD type, EWD stands for "Engine Warning Display" for displaying engine warnings) dedicated to generating warnings to the crew in case of failure of one of the engines Warning, and said interface device is also connected to a flight management system 8 (FMS type, FMS stands for "flight management system") which collects and compiles all flight parameters of the aircraft and manages the flight of the aircraft 1 .

[0018] The aircraft 1 also has a cockpit 10, in which is conventionally arranged at least one display screen 11 for displaying to the pilot warnings generated by monitoring means, and a man-machine interface 12 for controlling an engine connected to a control unit (e.g. , engine throttle...

Abstract

A method to automatically shutdown engines of a twin-engine aircraft where each engine is controlled by a control unit (4, 5) and an interface device (6) coordinates the control units; the control unit is configured to automatically activate a protection mode of the engine associated with the control unit (causing a virtually instantaneous shutdown of the engine) if the operation of the engine exhibits a functional abnormality; the interface device has first and second operating modes, wherein the switching between modes is based on the airspeed and altitude of the aircraft; wherein in the first operating mode, the automatic shutdown can take place only on the first of the two engines (2, 3) which exhibits an operational anomaly, and in the second operating mode, typically implemented during a cruise phase, the automatic shutdown will be able to be implemented on a first and then on a second engine (2, 3) if the second engine exhibits an operational anomaly more severe than the one exhibited by the first engine.

Description

technical field [0001] The invention relates to a method for the automatic shutdown of the engines of a twin-engine aircraft. Implementation of the method makes it possible to detect an abnormal operation of one or both of the two engines and, in certain situations, to automatically shut down the engine or engines exhibiting abnormal operation. Background technique [0002] Each aircraft engine is controlled and monitored by a control unit (FADEC type, FADEC stands for "Full Authority Digital Engine Computer": Engine Interface Computer) dedicated to it. The control unit is connected to an interface device that coordinates the control unit's control of the two engines (FMGEC type, FMGEC stands for "Flight Management Guidance Envelope Computer": the computer used to manage the flight, guidance and envelope). [0003] Each control unit automatically activates the protection mode when the engine exhibits abnormal operation. Activation of the protection mode results in a virtua...
