Wind direction/speed or headwind/crosswind information is displayed in a window below the Airspeed Indicator. The left side of the wind data box displays an arrow indicating the estimated wind direction and the heading from which the wind originates. The right side of the wind data box displays headwind ("H") or tailwind ("T") factor, the crosswind ("X") factor, and total wind speed ("@") in knots. If the measured wind speed is less than four knots "Calm Wind" is displayed in the window. When wind information is invalid or unavailable, the window displays "No Wind Data".
