ERROR ANALYSIS AND COMPUTATIONS OF WIND SPEED AND WIND DIRECTION FROM AIRCRAFT DOPPLER DATA.

Abstract

The use of a piloted aircraft to determine the magnitude and direction of the wind speed vector involves the direct measurement and recording of several basic parameters, such as ground speed, drift angle and air speed from which the wind speed vector is computed trigonometrically. This paper describes the significant mathematical relationships among these basic parameters, their errors and the resultant errors in wind speed and wind direction. After development of the general error equations, examples are given using Aircraft APN 102 Doppler data from typical flights made by a high altitude reconnaissance aircraft. (Author)
