The Wind Star of Air Navigation
Ralph Calvert · Mathematics Teacher Learning and Teaching PK-12 · 1944
The method for the construction of the wind star given herein differs from the usual method in that the radius of the compass rose is taken to represent the airspeed, and the drift angle is constructed by making use of the fact that an angle with its vertex on a circle is measured by one-half the arc intercepted on the circle. None of the books on the mathematics of aircraft navigation that I have had an opportunity to examine has given this construction.
