ground speed is ground speed and air speed is air speed...the two have nothing to do with one another....look at it this way...if you bring an aircraft into the wind strong enough that the airplane comes to a stop....ground speed is zero....but airspeed is what it is to remain airborne ...now turn the airplane down wind...don't increase power and your airspeed remained the same, but ground speed increased and you see the airplane rocket across the field...</p>

last year I came out of Memphis heading for Boston in a 727 made a turn to the east and ground speed shot up to over 600 MPH..airspeed remained the same....an airplane on approach will stall due to a lack of airspeed...not ground speed</p>
