Yep, that's what I want to do. Just have to wait 2 or 3 days more until they (the FOQA) download it. As for the wave... I did fly a glider in a mountain wave (last october acually), and know what it is. However, the departure airport was really far from ANY mountains, especially to the east (that's wehere the winds came from), so I think it must have been an inversion windshear after all
