Disclosed is a method and device for protecting an aircraft comprising at least one wing-mounted engine arranged on each of its wings against at least one of a low-energy situation and a high-energy situation during flight in which at least one engine is a failed engine. A control unit is triggered to activate a protection function, as a function of the number and position of failed engines. The control unit controls at least one non-failed engine, and the protection function is activated when activation conditions are met. The activation conditions indicate that the aircraft is either in the low-energy situation such that the total current power of the aircraft is less than a predetermined minimum power or that the aircraft is in the high-energy situation such that the total current power of the aircraft is greater than a predetermined maximum total power.

Method and device for the energy protection of an aircraft

Disclosed is a method and device for guiding an aircraft flying along a flight trajectory. The flight trajectory has at least one constrained section, and the aircraft flies at a required speed within the constrained section to comply with a required arrival time at a predetermined waypoint in the constrained section. Auxiliary speed setpoints are determined to guide the aircraft to arrive at an auxiliary arrival tune at an auxiliary waypoint, with the auxiliary speed setpoints being applied by a guidance system to guide the aircraft.
