True airspeed
True airspeed (TAS) is the speed of an aircraft relative to the airmass in which it flies, i.e. the magnitude of the
vector difference of the velocity of the aircraft and the velocity of the air. Under zero wind conditions and in horizontal flight, this is equal to the speed over the ground. Under wind conditions an estimation of the wind is used to make a windspeed vector calculation that computes an estimated ground speed from the true air speed and a wind correction angle to maintain the desired ground track.
