I think everyone understands the regs on this.
Maybe you were trying to be ironic or tongue-in-cheek, but I think you missed the poster's point: if both certified and non-certified aircraft are sharing the same airspace, why is it so important that the certified ones have TSO'd equipment, while the others don't? How does it make it safer that just some of the aircraft have TSO'd equipment? Or would make it unsafer if everyone used non-TSO'd? If non-TSO'd equipment is unsafe, why are they allowing a goodly portion of the fleet to use it?
It doesn't bother me. My aircraft are experimentals, and they're set with ADS-B in/out. But this is one of the major reasons that I *don't* own a certified aircraft.
