Abstract: The field of the invention is that of graphical libraries providing graphical functions used for the drawing of symbologic images. One of the fields of favored application is the generation of symbologic images for the piloting of aircraft. The object of the invention is to propose a method of graphical generation of a colored vector surrounded by a dark contour (H) on a background likewise colored as a single drawing, making it possible to preserve the function of antialiasing.

This method presents the following advantages: The calculations are optimized and successive writes to the buffer-memory are avoided; The dark contour is drawn at the same time as the vector of which it forms an integral part and thus becomes a functional state of the vector; The method takes into account the relative priority of the vectors with a single ordering logic.

Abstract: The field of the invention is that of optoelectronic taxiing-aid devices for aircraft, comprising a so-called head-up display enabling information to be presented in the visual field of the pilot. It applies more particularly to large civilian aircraft of the Boeing 747 or Airbus A380 type. The purpose of the invention is to present, in the display, a set of ergonomic symbols for informing the pilot of the path to be followed in a turn and the exact situation of his vehicle on the taxiway, enabling him to taxi in total safety, including in bad weather conditions. These symbols comprise lateral safety marks, represented by posts of variable height, representing the limit of the taxiway, positioned at regular intervals and located either side of the center line of the taxiway and equidistant from the latter. When the taxiing conditions are such that these posts are no longer visible in the display, a view from above of the situation of the aircraft on the taxiway is displayed.

Abstract: The field of the invention is that of methods of synthesizing cartographic images presented on display devices. This method is applied more specifically to visual flight on rotary-wing aircraft. The method according to the invention is used to present the useful aeronautical map information superimposed on a conventional altimetric presentation of the terrain being flown over, while retaining a legibility that is acceptable to the user. Flight safety is thus significantly reinforced. To obtain an enhanced legibility, the method displays only the aeronautical zones included in an altitude band corresponding to the flight phase of the aircraft and dependent on the geographic location and the vertical position of the aircraft. The method is used to display the cartographic representation either on a single window comprising a plan view of the terrain being flown over, or on two windows respectively representing a plan view and a cross-sectional view of the terrain being flown over.
