Abstract: A method for the three-dimensional representation of the trajectory of an aircraft in flight implemented in a navigation system of an aircraft is provided. The flight plan of the aircraft comprises imposed georeferenced trajectories and predicted non-georeferenced trajectories. When the trajectory of the aircraft is dependent on a non-georeferenced flight setpoint, the three-dimensional representation method is an iterative process comprising the following steps: computing a predicted trajectory arising from at least one computed trajectory extending over a determined distance or duration; computing a smoothed trajectory from the predicted trajectory in order to obtain a resulting trajectory; computing a displayed trajectory, the trajectory being equal to the resulting trajectory corrected for constant deviations or deviations depending on the application of setpoints from the flight director; and displaying the displayed trajectory.

Abstract: A method for the three-dimensional synthetic representation of the trajectory of an aircraft in flight being implemented in a flight and navigation system of an aircraft comprising a display system allowing synthetic images to be displayed, the flight plan of the aircraft comprises a predicted trajectory dependent on a non-georeferenced flight setpoint, the display of the predicted trajectory taking the form of a path represented by two limits separated by a determined width. The path comprises two branches, each branch positioned on the side of one of the two limits, each branch represented by a straight segment whose origin is a point located on the path at the current time and whose terminus is a point located at a determined distance away from the point of origin, the slope of the straight segment representative of the tangent to the predicted trajectory at the current time.

Abstract: A method for three-dimensional graphic representation of the outside landscape in an on-board display system for aircraft comprises a graphical computer and a display screen. The graphic representation is computed to a visibility distance. In the method the zero pitch line of the aircraft forms, with the real horizon line, a first angle, the line representing the limit of the visibility distance forming, with the real horizon line, a second angle, in a first step, the graphical computer determines the maximum visibility distance such that the difference between the first angle and the second angle remains less than a determined value; in a second step, the graphical computer determines the visibility distance as a function of the maximum visibility distance, of the maximum altitude of the relief of the local environment and of the flight phase.

Abstract: A method for guidance and for assisting in following a trajectory for velocity-vector piloting of an aircraft includes a step of calculating, at all times, lateral and vertical offsets of the current position of the aircraft from a target trajectory, estimated by a flight management system, and then a joining heading and a joining gradient for the aircraft to join the trajectory depending on these offsets; and a following fourth step of displaying, in head-up or head-down form, a consistent guidance symbol centered on the calculated joining heading and the calculated joining gradient for joining the trajectory, on a piloting screen showing a velocity vector. The fourth step may display, in addition to the guidance symbol, one or more items of information anticipating the next trajectory break.

Abstract: The general field of the invention is that of head viewing systems for aircraft comprising a head support, a viewing device, a detection of posture of said head support, means for detecting the current heading of an aircraft and means for graphically generating said heading. The system according to the invention comprises means of control, display and selection of headings arranged so as: to display, in response to a first command, a second so-called setpoint heading and a third heading termed a “support heading” corresponding to the direction of the head support in a terrestrial reference frame, said direction given by the information arising from the detection of posture of said head support and the means for detecting the current heading; to replace, in response to a second command, said second heading by said third heading, said third heading thus becoming the new heading setpoint.

In one aspect, the navigation aid information display system includes a display screen including at least one first display area configured to display a first altitude scale including graduations, the current altitude of the aircraft on the first scale, and set altitude value. The graduations of the first scale are distributed on an arc of a first disc including a first needle centered in the disc and the first needle is configured to indicate the current altitude on the first scale. The distribution of the graduations on the arc is nonlinear and symmetrical relative to a graduation corresponding to the set altitude value and defines extension graduations decreasing from the set altitude value.
