....components is shown in figure 1. Equations (3) identify parameters that make the most significant contributions in the calculation of ambient wind components. These equations can be used to estimate the required accuracy limits of these parameters for making useful air motion measurements. Lenschow (1986) discusses and provides an example of these limits for airplanes flying at 100 m s 1 , which approximates the typical airspeed of the TAMMS platform. 3. Instrumentation The Lockheed 188 Electra airplane (based at Wallops Flight Facility) shown in figure 2 has been outfitted with TAMMS which ....

....velocity fluctuation. The INS used by the TAMMS platform, therefore, easily meets this requirement. The vertical velocity of the airplane w p is derived by integrating the vertical acceleration output of the INS and bounding it by the third order barometricinertial loop algorithm as suggested by Lenschow (1986). The long term accuracy of the horizontal velocities u p and v p are dictated by INS drift rate. A thorough discussion of inertial systems and the errors present in the resultant velocity measurements are presented by Broxmeyer (1964) and Kayton and Fried (1969) Lenschow (1972) gives a general ....
