XPLM Navigation API

---

The XPLM Navigation APIs give you some access to the navigation databases inside X-Plane. X-Plane stores all navigation information in RAM, so by using these APIs you can gain access to most information without having to go to disk or parse the files yourself.

You can also use this API to program the FMS. You must use the navigation APIs to find the nav-aids you want to program into the FMS, since the FMS is powered internally by X-Plane's navigation database.
