Unfortunately the major glider equipment markets are not in the US. I
believe that WinPilot 9.0b complies with the majority of the contest
rules in the world although not in the US. But I may be wrong.
I guess a couple of pilots could install Flarm in their gliders in the
US, team fly and cheat, but is it worth it to win. You may get
caught, if WinPilot can read it then it is in the logger NMEA stream.
