DEGRADED OPERATING MODE FOR AN AIRCRAFT PROPULSION ASSEMBLY ENABLING REMOVAL OF A CAP TO A THRUST SETTING

摘要

A method and a device for controlling an aircraft propulsion assembly which mitigates the drawbacks of the application of a protection mode in which the maximum thrust is reduced (a degraded operating mode), in particular when an emergency situation occurs or the switch to protection mode is due to an incorrect analysis of the operating parameters of the propulsion assembly. The method includes a sequence of positions of the thrust control consisting in bringing the thrust control to idle then to setting it into the position corresponding to the desired thrust or a setting of the control to the maximum thrust position. Other simple sequences may include, the transition through the idling position with a transition to maximum thrust position, or through a succession of positions relative to the current position of the thrust control at the moment of the switch to degraded mode.
