The angular difference between the heading

and track is referred to as the drift angle (quoted

as being to port/left or starboard/right of the

heading). If the wind direction were in the same

direction as the aircraft heading, i.e. a tail wind,

the aircraft speed of 300 knots through the air

would equate to a ground speed of 310 knots.
