Having flown with the ZAON MRX for 2 seasons I find that alerting to
be useful. Certainly much more useful than "absolutely nothing to
protect us ".

As mentioned previously PowerFLRAM has the opportunity to be a big
improvement over the MRX if they include target specific alert
suppression. (let me mute the gliders I am thermalling with and still
be alerted to the B737 or King Air that is about to mow us all down)

Does anyone have any detailed technical data on how PowerFLARM is able
to distinguish a Mode C transponder equipped glider from a Mode C
transponder equipped powered aircraft?

ATC radar can track an individual Mode C transponder equipped aircraft,
because it can not only see the range and altitude of the aircraft's
location, but also the bearing. The PowerFLARM unit can not track the
transponder bearing, so some healthy skepticism is in order on the claim
that they can intelligently suppress glider induced false alarms while
not inadvertently also suppressing some real collision threats.
