Hi there - just lately it seems that lately after a flight in my own plane, when reviewing the flight in FlightAware, I will see occasional spikes in airspeed that are not possible for my plane/conditions. For example I might average anywhere from 120 - 150 knots more or less depending, but I will occasionally see close to 200 kts.
Is this a recent “feature”? I might hit 200 kts in a vertical dive if the wings fell off. Or maybe up high in a generous tailwind. But not just flying around in the local area. Let me know if I can provide more info. It does seem to mostly be ADSB reported as opposed to from Center or Approach etc.
