A system for piloting an aircraft during an autonomous approach for the purpose of landing. The piloting system has a flight guidance computer that directly computes, with the aid of a position indication and of information characterizing a virtual approach axis, linear deviations. Another computer computes aircraft piloting instructions using the linear deviations.

A method for monitoring the integrity of an aircraft position computed on board including on-board means for monitoring the aircraft position that are able to detect common-mode failures. Dissimilar computing channels of the aircraft position are utilized, the dissimilar channels being on-board in the aircraft. Each aircraft position primary computing channel is supplemented by a dissimilar computing channel, which allows the coherence of the primary aircraft position, the position computed by the primary computing channels, to be verified. Mechanisms for verifying the reliability of the results from dissimilar computing channels are implemented to limit a loss of performance from the utilization of dissimilar computing channels, which are less performing than primary computing channels.

Disclosed is a method and system for aiding the piloting of an aircraft to climb to a safety altitude situated above an existing low-height flight trajectory comprised of a lateral trajectory and a vertical trajectory, in which the safety altitude is the altitude of the aircraft that avoids collision of the aircraft with surrounding terrain. The aircraft is guided along the existing lateral trajectory of the low-height flight trajectory in a horizontal plane; and the aircraft is brought to the safety altitude by subjecting the aircraft to a climb mode in a vertical plane, which causes the aircraft to climb according to a climb slope which is greater than or equal to a maximum slope according to the existing vertical trajectory of the low-height flight trajectory.
摘要:
The invention relates to a method and a device for assisting the flying of an aircraft, said method and device being used to determine an approach path and comprising a guidance system for helping to guide the aircraft along this approach path. The inventive method and device define a main approach path (AI) and a corrected approach path that has an extra vertical margin (ΔH) related to the ground over which the craft is flying as compared with a main approach path representing a category 1 precision approach. Said guiding system guides the aircraft following the corrected approach path.
