[0233] According to a first embodiment, the conditions for engaging the second mode M2 ​​are met when one of the following conditions is true:

[0234] - the value of the acquired mechanical characteristic D, F for the main control member 22 , 23 , 24 corresponding to the considered aircraft axis is included in the third interval 64 or the fourth interval 66 , image 3 It can be seen and the aircraft is in a compatible flight envelope, ie the dynamics of the aircraft 10 are not excessive. In other words, the second mode M2 ​​may be selected if the dynamics of the aircraft for the coupling axis under consideration do not exceed a predetermined threshold; or

[0235] - the main control member 22, 23, 24 corresponding to the coupling axis under consideration is in neutral position, the aircraft 10 is stabilized on the affected cockpit axis, and the first mode M1 or the fourth mode M4 is inactive for the aircraft axis under consideration .

Abstract

The method makes it possible to generate a resulting setpoint trajectory of the aircraft (10), relative to which the guidance system controls the trajectory of the aircraft. The generation method is implemented by an electronic device (30) and includes: selecting at least one mode from several operating modes, obtaining a setpoint trajectory prepared by the flight management system (17), obtaining from a module for calculating the trajectory (40) and elements in the external generation system (18) obtain an alternative setpoint trajectory, and generate the resulting setpoint trajectory comprising one or several trajectory segments of the alternative setpoint trajectory corresponding to selecting another mode time period.

Description

technical field [0001] The invention relates to a method for generating a resulting setpoint trajectory of an aircraft for at least one receiving system of at least one guidance system of said aircraft, the resulting setpoint trajectory comprising At least one trajectory segment for at least one of the axes. The guidance system of the aircraft is configured to control the trajectory of the aircraft relative to the resulting setpoint trajectory. The method is implemented by an electronic device generating said trajectory. [0002] The invention also relates to an electronic device for generating such a trajectory. [0003] The invention also relates to an aircraft, such as an airplane or a helicopter, comprising such electronics for generating said resulting setpoint trajectory, a flight management system, an external setpoint trajectory generation system, one or several guidance systems, such as Autopilot and / or electrical flight commands and / or autopropulsion, the resultin...
