Applicability

This specification (APT.DAT 850) is supported in X-Plane 8.50 and later. However, the significant new feature set in this file version was not fully supported until the release of X-Plane 8.61.

The prior specification for airport data was APT.DAT 810, which is recommended for X-Plane 8.10 – 8.60.

Support for Deprecated File Formats

The deprecated file specification (APT.DAT 810) is still supported. A large quantity of custom airport data exists only in this format. So airports defined according to this specification (APT.DAT 810) can be included in a file otherwise complying with the APT.DAT 850 specification.
