I'm sad to say that at present, there is no wave window available in Petersburg, WV. As far as I know, I'm the last one to successfully climb into the wave window at Petersburg in 2013. (and I didn't get the diamond altitude because the Nano3 decided to not write a signature on the flight log. Ever since that day, that third diamond has been my nemesis! I rue the day!)
I've been working with the FSDO and ATC for the past 2 years to get a wave window established there.
Yes. Literally. 2 years.
My persistence is paying off. I'm really close to having one before March 2023.
At present, it's not clear if we'll be able to have gliders that aren't transponder and ADS-B equipped in the wave window. Right now, it looks like you'll have to be equipped to do this wave window. It's also not clear as to if the gliders have to be equipped with 1090ES. QQ is equipped in such a manner, but I don't know many other gliders around here that are. It might just be me who makes use of this new wave window.
Skyline Soaring club used to have another wave window in the Shenandoah valley, just west of New Market, VA. It was canceled by the FAA in 2020. It was in the one spot in the entire valley that had no wave at FL180 when the wind was coming from the northwest. It's really cool: Get a plot of SkySight on a wave day, show FL230, and draw a box where that wave window was. You'll never find any red in that box. No wave there. Just to the south there's wave galore! But not in that box. There's only been one person to get the diamond altitude in that wave window from 1993 to 2020. (Sounds like a crappy place to put a wave window if ya ask me). I had several examples of climbing under that wave window to 16,500, 17,000; and that was always a long slog at 0.1 knots.
