• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSX Multiweek FP to FS9

I've a multiweek FSX FP that I would like to use in FS9.

Before I try to re-invent the wheel and twist myself into knots, is there a method or does anyone know of anyway to do this.

Many Thanks

AIFP does not support conversion of FSX FPs back to FS9. (There was never any call for backwards conversion.) But that doesn't mean it can't be done with a little help. The issue will be airports in FSX that aren't available in FS9.

If you select FS9 as your Target Version before loading the FSX FP, AIFP may (the PV5-compatible current development release should), identify the airports of concern.) If that doesn't work, have a look at the files FS9Chg.txt and FS9Del_AIFP.txt in your AIFP folder. These files identify the airport changes from FS9 to FSX so you can determine which airports need attention manually.

In either case, save the FP as a fileset and update the airports in the FP text file using a text editor. Don't worry about the airports.txt file; AIFP doesn't use it.

You should now be able to load the edited FPs back into AIFP without error. Compile for FS9 and give it a try.

I can't guarantee this WILL work but it's worth a try.

I think he's talking about the fact that FS9 does not support multiweek plans, so that will need to be converted. The simplest way to do this is to split the plan into two WEEK plans and have two planes fly the routes weekly.

Thanks for the comments Tom. I hadn't bothered to check whether FS9 supported multi-week plans.. I just dove-in ( as usual).

So now there are two major issues - airports and splitting as you suggest.
The airports haven't created a problem, as they're all recognised.

It's the 5 week split that's not so easy to sort out.

Then the only other way I can think of is you load the traffic file and edit the repeat period of each FP to be weekly before saving to FS9
