About The Default Data
X-Plane airport and navigation data provides global coverage for airports, runways, taxiways, airport surface markings and lighting, NDBs, VORs, ILSs, fixes (intersections), airways and astronomical data.
The airport data includes all runways, and also includes detailed taxiway layouts, lights and markings. If no custom taxiway details are available, then the database will automatically generate a parallel taxiway system alongside each main runway – these are unlikely to be correct, but they will enhance the appearance of ‘unimproved’ airports.
Maintaining this data is a collaborative effort
If you see errors or omissions in the data, file a bug report on the NAVAID tab of the Gateway bug reporter. All data must be obtained from publicly available, freely redistributable sources. We cannot accept data extracted from commercially distributed database.
The X-Plane data is published under the terms of the Free Software Foundation General Public License (GPL). In summary, our interpretation of this license is that “works” published under the protection of its terms may be redistributed and modified, provided that this GPL remains a part of that redistribution. Nothing prevents you charging for any redistributed or derivative work based upon this data … but the terms of the GPL do not prevent (and are designed to encourage) someone else from later amending and then redistributing your work (or a derivative), either as free-ware or as pay-ware, under the same GPL terms.
