The purpose of the study is to define the simulation characteristics required to establish the simulator as a reliable and valid tool in the development of VSTOL aircraft and helicopters. A flight simulator employing the point light source principle to generate a visual display was used in these studies. Previous studies of a jet-lift VSTOL aircraft in this simulator uncovered a pilot-vehicle performance deficiency during lateral maneuvers, resulting in a nausea reaction which limited pilot participation. In the present investigation, human motion perception was studied, and solutions to this pilot-vehicle performance deficiency were evolved by the use of a moving base. The results demonstrated that effective simulation is possible when certain constraints are observed. The best constraints of the drive mechanism were determined experimentally and were compared with those implied from physiological concepts of human motion perception. A simulation validation rationale was also developed to assist the pilot in his evaluations. An example of this is described together with a discussion of some limitaions.
