Document updated March 18 1999 ============================== Change log: ----------- Mar 18 1999 version 1.22: -New codes for runway markings -Runway surface codes changed Mar 17 1999: -Runway Stopways added -Displaced runway thresholds added -Approach light codes changed General ------- This document describes the new prototype data files for X-Plane. The files are: default.apt (airports and runways) default.nav (VORs, NDBs and DME) default.ils (ILS) default.fix (IFR intersections) The data in the example files is _not_ limited to 15 per lat lon square - the files are still similar in size to the existing ones, despite much new data. Contact me with any questions at robin@cpwd.com. Contents of each file are: ======== Airports ======== AptType AptCode AptLat AptLon AptElev AptUse (Civil/military) AptTwr AptBdg (Y=Use X-Plane default buildings) AptName Runways ======= RwyType RwyNo RwyLat RwyLon RwyHdg (note new precision) RwyLen RwyWidth RwySfc RwyMrk RwyEdgeLx RwyCLLx RwyGuard (aka wig wags) RwyTDZLxA (First runway end - A ...) RwyREILA RwyGSIndA RwyAppLxA RwyDispThrA RwyStopwayA RwyTDZLxB (First runway end - B ...) RwyREILB RwyGSIndB RwyAppLxB RwyDispThrB RwyStopwayB Fields are in two different types of rows. The airport data is categorised by AptType as: A = Airport S = Seaplane base (note - these should have different airport beacon colours - see AIM). Apt Use is C (Civil), M (Military). Runways are identified by a leading R as RwyType (and H may be used later for Helipads). There are no runways for Seaplane Bases (though if you want to display bobbing bouys in the waves I can create such data). Note that the total runway length includes displaced thresholds but excludes stopways.
