Flarm and PowerFLARM have to be 100% compatible and Flarm does not use
pressure altitude in its collision avoidance protocol. And I want to
qualify that as far as I know PowerFLARM does not transmit pressure
altitude, but it might, I dont know.

It must transmit pressure altitude, as otherwise the altitude reading
displaying on SeeYou next to another glider is GPS altitude. *I can't
compare that to the altitude on my altimeter.

Greg,

O ye, of little faith. Wanna bet a case of good San Ynetz area wine?
