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.

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.
