DEGRADED OPERATION MODE OF AN AIRCRAFT POWER PLANT ALLOWING THE REMOVAL OF THE CEILING OF A THRUST SETPOINT

摘要

The invention relates to a method for controlling a propulsion unit (2) governed by a controller (3) generating a thrust command applied to the propulsion unit (2) as a function of the position of a thrust control (4). . The controller (3) has a nominal operating mode and a degraded operating mode in which the thrust reference is capped which limits the thrust to a predefined threshold. In the degraded mode, the realization of a predetermined sequence of positions of the thrust control (4) authorizes the generation and application of a thrust instruction corresponding to a thrust greater than said predefined threshold. The pilot can thus, without having to perform additional or non-intuitive maneuvers to disable the degraded mode, get an extra push when necessary, without leaving the degraded mode. The invention also relates to corresponding device and to an aircraft comprising such a device.
