Flight Plan Documentation

[Luke Kolin]

I'm looking at extending our ACARS software to support X-Plane 9. Is there any docomeentation on what an X-Plane flight plan file (the equivalent of an MSFS .PLN file) is like?

 

Cheers!

 

Luke

They're actually .fms files.

 

I can't tell you what the I 3 version 4 1 stuff is at the top... so we'll start where the actual plan comes in.

 

First Line: The 28 means its a lat/lon coord. I don't know what it is, most likely what INIT or something... I dont know, I didnt put that in my flight plan...

 

11 EH001 11: Means its a fix I entered. EH001, is the fix itself on the RNAV departure.

 

7000.000000 What altitude I programmed for the initial flight level for that fix.

 

And then its latitude and longitude. And its the same for everything.

 

So basically, you have what it is, it's name, altitude to be flown at (0000.000000 means right up to cruise... not actually 0 feet.) Then its latitude/longitude. -> Type-Name-Altitude-Coordinates

 

28: Coord

 

11: FIX

 

3: VOR

 

2:NDB

 

1: Im guessing it's an AIRPORT, not sure though.

 

Oh yea, and the lat/lon in between EH026 and ARNEM is when the controller gave me a direct to ARNEM.

 

I think I answered your question to some extent.

Luke, did this help you, or was I off course?

Luke, did this help you, or was I off course?

 

Terribly sorry, I lost track of this one. That looks fantastic and I will try it out later this week.

 

Cheers!

Started digging through this tonight, rewriting all of my flight plan handling code.

 

Just to confirm, the FMS file does not contain any altitude information, or the departure/arrival airports?

 

Cheers!

[Charan Kumar]

the 3rd parameter is the altitude if I am not mistaken...here's the infamous rte form ZOA artcc:

Since XPlane FMS is pretty much nav from present location, you can have ur first parameter as the airport for distance calculation, but not necessary.

Luke: you do realize the X-plane demo is free and there's no limit on the use of the FMS
