摘要:
The invention is situated in the field of displaying on board an aircraft geostationary elements of the navigation database on a screen having different display resolutions for the purpose of this data display, and its subject is a method for simplifying the display of stationary elements of this onboard database. This method is characterized in that it consists in precalculating a “decluttering” during the process of producing the onboard database by meshing the Earth with a Cartesian grid oriented along the latitudes and longitudes of the Earth, and by allowing only the most pertinent obstacle to appear in each rectangle of this grid.

This disclosure relates to a system for preventing collisions with a terrain. The system includes a detecting means for detecting risks of collision with the terrain after a predetermined forecasting delay. The system further includes a determining means for determining, based on a trajectory followed by the aircraft, a possible limit point for success of the vertical terrain avoidance maneuver. The system further includes indication means for giving indications on azimuth clearance sections, around the direction in which the aircraft is moving, suitable for success of the vertical terrain avoidance maneuver. The system further includes means for estimating a free-travel distance in each azimuth clearance sector on a straight distancing trajectory with constant gradient and over a distance correspond to more than one minute of flight, the free-travel distance being free of potential conflicts with the terrain. The system further includes means for signaling azimuth clearance sections and free-travel distances.

The invention relates to a monitoring device and method allowing surveillance of an aircraft in relation to aircraft and/or craft on an airport displacement zone. The invention is a system comprising a dedicated transmitter and receiver to receive the information regarding the location and displacement of the cooperative aircraft and to monitor the location of the said aircraft in relation to the cooperative aircraft. The monitoring application is based on the detection of conflict zones by inter-correlation of constraint surfaces of the airport zone. The invention applies to aircraft carrying communication moans for ADS-B networks for an airport zone monitoring application.

The present invention relates to a method of protecting an aircraft in approach by signalling against the risks of collision with the terrain in steep-sided environments, in order to avoid unwanted warnings emanating from the clearance sensors of the onboard TAWS system while protecting the aircraft when it fails to observe the published procedure, and this equally in a landing procedure and in a take-off procedure. The method includes conferring an additional function on the conventional TAWS functions, specific to the detection of the potential risks of collision of the aircraft with the terrain when following procedures of reduced protection corridor type, and this without modifying either the logics or the characteristics of the clearance sensor or sensors as currently defined in the TAWSs of the state of the art.

A method and a device for detecting a thrust dissymmetry of an aircraft during a landing are disclosed. The detection device (6) comprises means (7) for detecting, upon a landing, that at least one of the engine control levers occupies an intermediary position comprised between a position threshold and a maximum speed position, as well as at least another engine control lever occupies an idling position, and means (9, 13) for triggering a warning when a landing condition is validated and at least one of the control levers occupies said intermediary position, at least another control lever occupying said idling position.

In distance maps used in order to facilitate the navigation of craft such as an aircraft, the distances estimated take into account obstacles to be circumvented but not the maneuverability of the craft. The adaptation route required by the craft in order to take the right direction is not taken into account so that certain distance estimates for accessible points located in the neighborhood of the craft are unrealistic. In order to make a distance map more realistic, it is proposed that an obstacle of concave shape associated with the craft be added behind the position of the craft, forcing the estimations of distances to be circumvented an area that is inaccessible to the craft for reasons of maneuverability.
