A very accurate measurement and data recording system has been developed to evaluate the applicability of a dynamic flight test technique. By this technique, performance data are extracted from a single dynamic manoeuvre of an aircraft. Application of the technique reduces the large amount of flight hours that would be required for the determination of these data by means of measurements in steady flight. An inertial strapdown system forms an important part of the measurement system. It senses three angular rates and three accelerations of the aircraft by strapped-down gyroscopes and accelerometers. The signals are measured with an accuracy of 1 ± 10^-4 or better. They are sampled 64 times per second and converted into digital words of 16 bits, which are transmitted to the data recording equipment. This report gives a description of this inertial measuring and conditioning equipment, IMAC.
