Abstract: The invention relates to a method for optimizing the display of data relating to the risks associated with obstacles. The method includes extracting from an obstacle database, a list of obstacles included in the geographic zone defined by the range, the orientation and the position of the aircraft. Obstacle related information and warning lists are received. The obstacle list is regrouped by applying to the obstacles criteria relating to the proximity of the obstacles relative to the aircraft; to the proximity of the obstacles to one another; and to their warning level. The symbology adapted to the obstacle display is generated. In particular, the invention applies to optimizing the display of warnings relating to the risks of collision with point-like or linear obstacles.

Abstract: The invention relates to a database and a method of generating a database containing topographical information on obstacles distributed over a geographic area subdivided into cells. The method includes reading topographical data obtained from heterogeneous sources. Topographical data are generated which relate to pointlike obstacles from the information collected from the topographical data. Topographical data are generated which relate to linear obstacles from the information collected from the topographical data. The obstacle database is created. Each cell contains a link to the obstacles whose coordinates in the geographic area covered by the cell are recorded with an uncertainty value. In particular, the invention applies to the generation of a database on board an aircraft.

Abstract: The invention notably relates to a method of detecting obstacles on the ground receiving an obstacle clearance sensor and a zone for extracting map data. The method comprises the following steps: extraction from an obstacle database of a list of pointlike obstacles; extraction from an obstacle database of a list of linear obstacles; determination, according to the obstacle clearance sensor, of the risks associated with the extracted pointlike obstacles and generation of a warning; determination, according to the obstacle clearance sensor, of the risks associated with the extracted linear obstacles, and generation of a warning. In particular, the invention applies to the calculation of the warnings relating to the risks of collision with pointlike or linear obstacles taking into account the path of the aircraft and the altitude of the obstacles.

Abstract: The present invention relates to a method for homogenizing measurement units used for displaying communication messages containing numerical data notably messages exchanged by an aircraft with the air traffic control authority. The choice of the working units of the flight management computer are recovered in the configuration database. The measurement unit of the numerical data item of the displayed message is determined. When the measurement unit of the numerical data item of the message does not form part of the system of measurement units, the numerical data item is connected into a unit forming part of the system of units. The display of the communication message on the onboard screen is formatted.

Abstract: The present invention concerns a method and a system for filtering tracks originating from several sources and intended for several clients to which they are supplied. The method comprises at least a phase (8) for establishing a link between tracks resulting from a single aircraft and a phase for selecting one of the linked tracks to represent the aircraft according to a client-dependent criterion, so that a single client may not receive several distinct tracks representing the single aircraft but so that distinct clients may receive distinct tracks representing the single aircraft.

Abstract: The present invention relates to the determination of the ground address that an aircraft must call within the aeronautical telecommunication network ATN to prepare a context for digital data exchanges with a ground air traffic control center. It consists in using the GSIF general data broadcast by certain ground telecommunication stations, including VDL ground stations, to enable the router on board an aircraft passing through the coverage area of a routing center to undertake an automatic handshake procedure. This operation consists in identifying the ground telecommunication station concerned by its GSIF data, locating it from this identification and selecting the address of the ground CM application of the air traffic control center closest to the identified ground telecommunication station from a file of ground CM application addresses organized by geographical areas.
