Survey of flight simulation computation methods.

A historical review of developments in flight simulator computation methods indicates that the computation load has been increasing by about a factor of ten every ten years for the last thirty years. From a brief analysis of computation methods used on a typical modern digital flight simulator it is concluded that these methods are more than adequate for the simulation task as presently defined. Additional new simulation requirements such as computer-aided instruction methods and computer-based navigation techniques apparently will require very large additional simulator computer capacity in the near future.
