Abstract:
Methods and systems for assisting the piloting of an aircraft are provided. The system includes at least one avionics type system and at least one non-avionics type system. The method includes steps involving receiving avionics type data associated with a flying context of the aircraft; forwarding the avionics type data to a non-avionics type system or computer; determining, in the non-avionics computer, one or more adjustment recommendations for equipment based on the received flying context and/or on predetermined data; displaying one or more recommendations. Various developments are described, in particular the conditions for requesting and/or computing recommendations (e.g. ongoing adjustment of the avionics, similar previous configuration, etc.), the selection and the categorization of recommendations, the handling of adjustment data for the avionics, etc. Software aspects are described.

Abstract:
Disclosed is a method of detecting a signal from a user to generate at least one control instruction for avionics equipment of an aircraft, implemented by an electronic detection device. The method includes the detection of a first user signal, and determination, according to the first detected signal, of a control mode from a plurality of control modes. It includes the detection of a second user signal that is distinct from the first signal, and confirmation of the determined control mode, according to the second detected signal. It includes the detection of a third user signal that is distinct from the second signal, and the selection, according to the third detected signal, of a control instruction from the control instruction(s) associated with the confirmed control mode. At least one of the first, second and third detected signals is a gestural signal.
Abstract:
The general field of the invention is that of methods for determining safety zones surrounding an aircraft travelling or taking off from an airport zone, the safety zone being calculated at a determined instant that may be the present instant or the future instant. The method according to the invention comprises at least the following steps: Step 0: Establishment of a convex safety envelope surrounding the aircraft on the basis of reference points taken on the aircraft; Step 1: Establishment of a first convex envelope safety zone surrounding the aircraft on the basis of reference circles taken on the aircraft, each circle having as centre one of the reference points and as radius the value of the uncertainty in the exact position of the aircraft. Other steps of the method make it possible to refine this first safety zone depending on whether the aircraft is in a taxiing or takeoff phase and depending on whether it is calculated at the present instant or at the future instant.
