We are all on the same page, but just someth8ng for the poitive_negative guys to mull- you are defining positive ground speed as being in the direction the aircaft is ponting- well, if there is any cross wind, the aircraft isn' t tracking that way- so is a teack 30 degrees off the nose " moslty positove "
answering the question on a 50 knot airspeed in a 60 knot headwind- how far will the aircaft be from its starting position after one hour?
