The thing is, a pitot tube can ONLY be used to calculate AIRspeed - via comparing the static air pressure sensed wherever it is (on the FDR box itself, right?) and the dynamic pressure from the pitot tube.

So where you mention a "problem" because the airspeed reported into a headwind was higher than the groundspeed is not really a problem - it IS the AIRSPEED after all that the unit is measuring. It cannot measure ground speed.
