Abstract: A method of generating a peripheral image of an aircraft having pixels obtained from a plurality of cameras equipping the aircraft. The method is implemented by an electronic generation device. The method comprises a step of receiving a position of a peripheral point of view from which the peripheral image is to be generated. The method comprises steps of obtaining an orientation of the aircraft and of acquisition of a respective image from each camera. The method comprises a step of calculating a respective transfer function for each camera, each transfer function being intended for being applied to a pixel of the peripheral image so as to identify a possible corresponding pixel of the acquired image associated with the transfer function. The method comprises a step of generating the peripheral image from the images acquired from each camera and from each calculated transfer function.

Abstract: The invention relates to a method for securing the operation of a synthetic viewing system of an aircraft. This method comprises the steps of determining at least one control object in the field of view of the synthetic vision system and determining at least one control point belonging to each control object and verifying the consistency of the display of the synthetic vision system. The verification step comprises the sub-steps of recovering a first position corresponding to the displayed position of each control point on the corresponding outline on the display of the synthetic vision system, determining a second position of each control point on the display of the synthetic vision system and comparing the first and second positions.

Abstract: The general field of the invention is that of the methods for graphic representation of the relative position of the sky and of the earth in an onboard display system for aircraft, said graphic representation being displayed on a display screen comprising piloting and navigation information superimposed on a three-dimensional synthetic representation of the outside landscape. Said graphic representation is displayed only when the attitude of the aircraft is unusual, an unusual attitude corresponding to a roll value or to a pitch value located outside of a first range of nominal values. It comprises two disc segments of identical form, that are opaque and of different colour, situated symmetrically on a circle concentric to that bearing the roll scale, the straight-line segments of the two disc segments being parallel to the line representing the zero longitudinal trim indicator, the rotation of the two disc segments being slaved to the rotation of said zero longitudinal trim indicator.

Abstract: The general field of the invention is that of the graphical representation of a synthetic three-dimensional view of the exterior landscape in an on-board visualization system for aircraft, said graphical representation being displayed on a visualization screen comprising the piloting and navigation information of said aircraft superposed onto said three-dimensional synthetic representation of the exterior landscape, said synthetic representation being computed up to a first determined distance, characterized in that said three-dimensional synthetic representation is tilted at a tilt angle about an axis positioned at the level of the terrain in a substantially horizontal plane, and substantially perpendicularly to an axis between the flight direction and the heading of the aircraft, said axis moving with the aircraft.

Abstract: The general field of the invention is that of the methods for three-dimensional graphic representation of at least one landing runway on a display device of an onboard display system for aircraft, said graphic representation being displayed in a synthetic of an outside landscape, said runway comprising a coloured rectangular form, an outline surrounding said form and markings the position of the aircraft in relation to said runway being known in a horizontal plane with a first accuracy and in a vertical axis with a second accuracy. When the first accuracy is above a first threshold and/or when the second accuracy is above a second threshold, the appearance of the rectangular form or of the outline or of at least one marking is modified.

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: The field of the invention is that of systems comprising command or control facilities possessing a considerable set of viewing devices having to display a large number of parameters according to precise configurations such as, for example, the instrument panels of modern aircraft comprising several “displays”. The subject of the invention is a method of configuring or reconfiguring a plurality of displays on a set of viewing devices, configuration or reconfiguration being induced by an event, certain viewing devices being able to display several different formats simultaneously. Each elementary configuration is obtained essentially by means of a reconfiguration logic language and of an interpretation algorithm, the said logic language comprising essentially a reconfiguration domain, properties, transition rules and preferences and the said interpretation algorithm making it possible to transform each transition rule into a list of elementary reconfigurations.
