The problem with PowerFLARM today is that it does not reliably show you all GA traffic. It does NOT support TIS-B or UAT, so you will not see ADS-B equipped aircraft that use UAT for ADS-B OUT. This is going to be a VERY significant proportion of the GA fleet, given uAvionix's low cost and easy to install SkyBeacon and TailBeacon products.

Unless you have flown in an ADS-B IN and OUT equipped aircraft, you really have no idea of how much traffic is out there, even in remote areas. If you look at where gliders are based in the US, I suspect the majority are in relatively close proximity to major metropolitan areas where GA and airliner threats are significant. Even if you are flying in Janesville, WI (90 miles from ORD), you have jets on approach to O'Hara flying thru your airspace at 7,000 ft.

Mike, do you have any figures to back up your UAT vs 1090ES adoption rate assumption? Sure as heck no jets or high performance/IFR aircraft will go UAT!

And, as usual, you ignore that PowerFLARM DOES pick up UAT-equipped aircraft BY MEANS OF PCAS DETECTION OF THE TRANSPONDER. Sure it isn't as good as a full up ADS-B in, but it is a lot better than nothing or the old Mk 1 eyeball!
