Abstract : This report discusses the principles of operation and the various machine errors of airborne flight loads measuring equipment. The categories of equipment covered are angle of attack sensors, gyroscopes, accelerometers, strain gages, pressure transducers, signal conditioning equipment, and magnetic tape recorders. Machine errors are classified as being either intrinsic, environmentally induced, or attributable to usage or application. The errors are further classified in accordance with their effect on the measured data. The principles of operation and errors are expressed either with mathematical formulae or by indicating the state-of-the-art performance. Methods for minimizing both the errors and the effect of the errors are indicated. (Author)
