Abstract: A control method for controlling aerodynamic means of an aircraft having mechanically decoupled flight controls enabling the aircraft to be piloted by at least two pilots. The aircraft has at least two control members operated by respective ones of the at least two pilots and each enabling control signals to be generated for causing the aerodynamic means to move relative to an incident air stream. The control method includes piloting logic (“operational” logic). The operational logic includes a dual operating mode in which each control member can control the aerodynamic means. In the dual operating mode, only one of the at least two control members, (the “activated” member), has exclusive control over a full travel amplitude of the aerodynamic means. The other control member, (the “deactivated” member), then is temporarily inoperative on the aerodynamic means.

Abstract: A system of an aircraft for signaling the presence of an obstacle during visual flight, which system includes at least one onboard unit to be installed in an aircraft to be equipped, which onboard unit includes an onboard database that stores at least one obstacle to be avoided during flight. The onboard unit includes an interface to be installed in the aircraft and whose function is to authorize the addition and the deletion of obstacles in the onboard database, with the interface being in communication with the onboard database.

Abstract: A method of contributing to making safe a synthetic vision display of an aircraft for displaying on viewing means an at least partial view in perspective of the environment of the aircraft together with piloting symbology. During the method, at least one check point (P1, P2, P3) is defined that is situated in the environment and that co-operates with a reference point (Pr) of the aircraft to form a first straight line (DP). Thereafter, a first display function (F1) is used to calculate display coordinates (a1,b2), (a2,b2), (a3,b3) for each check point (P1, P2, P3) on the viewing means, and then the inverse (F2)?1 of a second display function (F2) is used together with the display coordinates (a1,b2), (a2,b2), (a3,b3) to calculate a second straight line (DS) passing through the reference point (Dr). Finally, the first and second lines (DP, DS) corresponding to a common check point (P1, P2, P3) are compared in order to define whether the synthetic vision display is trustworthy.

Abstract: Disclosed is a method and device, which provide an enhanced ability to monitor the navigation of an aircraft during a phase of flight in which the aircraft is close to the ground in which the aircraft uses positional information supplied by a satellite positioning system for the navigation. A display screen is used to display a first characteristic sign representing a selected setpoint value for a height parameter of the aircraft. The display screen also displays a second characteristic sign representing a current auxiliary value expressed in the form of an achievable height parameter. An alert is emitted when the second characteristic sign is determined to be within a predetermined height value of the first characteristic sign, and the alert is shown in visual format on the display screen. An alarm is also emitted following a predetermined time after the alert is emitted, if the setpoint value is not replaced by a new setpoint value.
