Just so we do not get too high on our horse, I recently became aware (and check 4 sale adds on W&W) many gliders DO NOT have power Flarm. One pilot was just asking about renting a unit for the Standard Class Nationals, as he was not ready to buy yet! When i was flying powered aircraft, I had an S-mode transponder and Sandel HSI which helped point out traffic, on many occasions I was glad and I paid the money At that time TCAS was about $30,000.. I am not a firm believer in the "Big Sky" theory, from personal experience swapping paint, and several Very near misses while both myself and the other aircraft were under positive control, twice at an airport, Santa Barbra and Torrence.

Indeed most GA never heard of PowerFlarm.
The soaring community is obviously ahead of power pilots with collision avoidance technology, and the reason is that we took the matter in our own hands and did not wait for the FAA to protect us. It is too bad that most GA is still depending on See and Avoid when the technology exists for more than a decade!
