Hi Steve, the great thing if you guys are on SkySafe is everyone will know you are about and either look out for you or steer clear.
I've seen several of your peers on it testing already and when I'm flying it will be great information, especially when you are cliff or ridge soaring and there's a bunch of you. I have PAW and use FR24 now and again (I live near Helo corridor) and have recently added Sky Safe.
I doubt GA with transponders only will know where we are. It needs an internet connection and isn't universal yet...
I'm slightly keener on FLARM (or FANET+) as it will go direct peer to peer on Sky Echo 2, which has proved to be the most popular EC rebate device, and on PAW via ATOM as well as to FLARM itself. Like I said, we've been using these devices and apps for over ten years, drop out and some slight inaccuracy can be an issue. In competitions if there is a problem then there is an appeals procedure using a locally recorded GPS track either in the hardware tracker or from another device.
I've looked at Safe Sky and it seems to have a slower update rate than FR24, or maybe that was just my internet connection, which proves the point.
I'm looking at doing something on the most recent Isle of Wight ground station.
I'd love to see some figures on latency. That's the elephant in the room...
