I wonder what percentage of LAA types are unable to fit a transponder (because of weight or power) and what percentage are unwilling because of cost?
Or just don't want to full stop? Bear in mind the recent campaign by the LAA (and others) to stop mandatory Xpdrs...
I am not sure it would achieve much, since mid-airs seem to happen in the lower levels (?), and you would still have to transit in and out of the "upper areas" through the "danger zone" (unless you could confine that to CAS).
The 10,000' is a long established rule? What would you change it to? On what basis/reasoning? What arguments would alter the debate we have just been through? Would it be amsl? Or agl?
