This means it's just about the slowest conceivable way to generate the display (using OpenGL), but was relatively easy to develop quickly. The current display is implemented almost entirely using individual OpenGL calls, with no state tracking or inter-frame persistence of symbol data. The original code was an experiment - hopefully it is useful, but the primary aim was to investigate creating such displays, as a precursor to developing accurate in-panel displays in the future. When tuned to an ILS, the corresponding localizer will be displayed in cyan instead of blue.įor FlightGear 2.99/3.0+ please also see MapStructure and A Canvas-based Map dialog The tuned VOR(s) and their selected radials and range-circle will be displayed (in cyan), assuming the aircraft is within range of the station. Control-click to place a marker point - a line (in cyan) will be drawn from the aircraft position to this location, and the distance and bearing will be displayed (and updated as the aircraft moves). You can also pan using the cursor (arrow) keys, and zoom using the +/- keys. Open menu "Equipment" and activate "Map".ĭrag with left mouse button to pan the map, and use the mouse-wheel to zoom in and out. Make sure you see the menu bar (F10 to toggle). (Some of the symbology and colours used are intentionally similar to a Boeing ND) Optionally, the map can be orientated so that the aircraft heading points upwards, allowing the map to be used as a crude generic navigation display. Data can be shown about items in the map, such as the frequencies of a navaid, or the length and bearing of a route leg.Īircraft information is also shown, notably the current ground track (derived from the GPS) and heading. Multiplayer traffic can be shown, and in the future airways, obstacles and other object types may be displayed. It does not display any geographical data (borders, coastlines, roads or rivers) at all, though support for basic borders and coastlines may be added in the future. The map dialog aims to provide a visual representation of navigation data in the simulator - i.e airports, runways, navaids, and so on.
