Hi...all those pln to rte tools that I found don't work and since the pln format of FSX is easy to understand I wanted to write my own converter (I'll send you the source code when it's done), but my problem is, that I can only guess how the rte files have to be built... is there some documentation about that?thanks a lot...

oh... it's possible to import PLN's directly... why didn't you tell me that earlier? :-)
