Information models for designing conceptual broad-profile flight simulators

The problems of simulation are those of reproducing established flight cond itions, the preconditions for special situations, and the way such situatio ns proceed in the course of both proper and improper actions by an aircrew in the entire range of anticipated operating conditions adopted for the sim ulation. Here the fundamental questions are considered of the theory and pr actice of a flight simulator, its present state and its future promise.
