The formation de site is not restricted to a particular aircraft. It applies to any aircraft having “similar performance” – however that might be interpreted.
But is there actually anyone who doesn’t have a D140? 
In France if they don’t have one, they want one.😁
So, if you want to use a different aircraft category than what they have in the club, you need to bring the aircraft with someone who has it before you can do the site training?
Yes.
Alternatively, you could fly your PC12 or DC3 or whatever to Annemasse, grab their MOU instructor by the wallet, fly up to Courchevel with him, do a few circuits, and fly away with the necessary endorsement in your logbook.
Incidentally, and despite the Apple spell-checker’s insistence to the contrary, the altiport is called Courchevel, not Courcheval.
I kinda hijacked another thread, apologies… so here’s a re-post with a motivational video.
Friends Alex and Fabian have published this little vid a few days ago. They have the MOU rating and fly in there (taking foldable skis along) in their fantastic RV-14A 😎
Nice video – us inhabitants of Großbrexitland no longer can add a MOU rating to our UK CAA licence, at least I think that’s right. Still would like to organise the training at Belluno/Bolzano, where I believe they also add the ski operations to altiport operations.
