i thought it might be interesting to collect all material about waves in the new porta-westfalica scenery here.
As the scenery doesn't contain real mountains but only hills, it's quite interesting to discover the waves there.
Until now, i found one wave. You can find it when using the flightplan which is runing on my freeflight server: inversion 700m, windspeed 65km/h, wind direction: 209Â°.
Go to Ithwiesen and use to ridge-part short before the airport to climb to ~1200m. It's quite hard but it works. After climbing at the ridge i entered the wave at about 1270m in the lee of the hill west of Ithwiesen. The wave reaches until ~2300m.
