ABSTRACT
Unlike flight simulators used for training purposes, those used in research have demanded very high levels of physical fidelity. Generally, such simulators fall in two general categories. The first category represents those purpose-built to support a particular research program such as the study of aircraft handling qualities or the optimum design of a flight deck. A second category of research simulators consist of those that are modified versions of simulators which were originally design for training. These devices have the advantage of lower cost and the high reliability built into training devices. They are especially useful in research programs where extensive modifications or changes to the simulator design are not required.
