Glider pilots. If the safety experts dictate a change then so be it. Live with it like we all have to in powered flight. So your glide ratio is lessened. Won't that apply to everyone so the level playing field remains. many of us don't need or want FM immune radio fits. BUT if we want to use certain airspace then we have to have it fitted. If it is decreed that a transponder is required to be used for any flight then as I said so be it
