I need to design some instrument approach procedure chart for a fictional airport Flight Sim. scenery I work on.

I remember a decade or so ago there was one available. I think it was "Final Approach".

It was pretty simple and did the job fine but I can't trace it back now.

Just found this and it looks like it has developed to a professional software and its interesting when you consider it started from an old Flight Sim application.

Question : Any ideas how to make some simple approach plates for flight sim use without professional software ?

I have sketched them in plain paper and they're fine but would rather have them in "designed" format.

Don't quote me on this but check out Freemind it's open source.

I noticed that ArcGIS has an aeronautical charting package however that is also professional software, but I started looking to see if there was anything for the free QGIS software and found this:
