Well Im not going to claim any expertise as I am not a pilot. All I will say though is that I just submitted a flight test plan to transport Canada a few days ago that includes a section for airspeed calibration. We will be ensuring that the standard aircraft airspeed instrumentation will match the gps ground speed (within reason). This will be in a bell 412.
I've done this test once before and the gps speed indication is pretty accurate. So I really don't know what to say. Of course the airplane's systems most likely run off the the indicated airspeed, and don't even consider the gps. But I'm just speculating.
But wow. Gives me chills reading that.
