This approach pattern is not going to work for everyone ALL the time, but if you watch the wind socks as you approach (when they’re not pointing at each other) and you’re not landing in the middle of a hot day when dust devils are common, this approach pattern will work great and isn’t a risk of you dying if you use it. It’s the only one I’ve been using since I’ve started flying a PG, and I’ve never had an issue with it. I’m out of the way of hang gliders, I’ve not landed into a dust devil (thus far), and haven’t seen anyone else do so yet with my own eyes.
Besides, dust devils don’t just stick to the parking lot area, they’re on the grass too, they just don’t have any dust to pick up to make themselves visible. I’ve seen them go all the way over to the hang glider side. You’re not much safer from them over there, but now you just might get in the way of a hang glider.
Unless you’re great at looking around and making sure no hang gliders are coming in at the same time as you, landing in the hang glider pattern as a PG is asking for problems. There’s a major conflict of speed. HGs are a lot faster than we are, and we can’t get out of their way fast enough. We’ve had way too many of these in the last few months. That’s why the approach pattern keeps coming up. If some of these PGs were good at keeping an eye out, we could easily share the same pattern, but they’re not. They prove it over and over again.
