Andrew,I have just checked on the Swiss VATSIM site and they do not appear to have any charts for download
Since the demise of the FSS project charts have become difficult to obtain for Europe.
I ended up generating a FP in FSNav, at least I can SEE the airways with that . I do use FSbuild but have found the UK and Europe routes a little suspect in that the airways are not always the same as in FSNav.
If the FSNav route is of any use give me a shout and I will e-mail it to you; it is from EGCC though, not from EGLL or EGSH
