Manned Engineering Flight Simulation Validation. Part I. Simulation Requirements and Simulator Motion System Performance.

Abstract
The goal of this research is to establish an orderly, relatively simple method for optimizing the presentation of motion cues in moving base simulations. This is accomplished via choice of the drive logic parameters for a given simulator and flying task. The method developed here is based upon use of motion fidelity criteria. It has been applied to optimize the LAMARS motion base drive logic parameters for an air-to-ground scenario. The methods and procedures of this report can be applied for any given motion base and any desired scenario. Criteria for discerning fidelity of motion reproduction are developed. These criteria are composed of various mean-square error measures which reflect differences between simulated and actual in-flight motion. The criteria can be used to answer three questions which arise for every motion base simulation program: is moving base simulation appropriate for the flying tasks to be investigated, how can motion base drive logic parameters be optimized for the flying tasks to be investigated, and will this set of motion drive logic parameters result in motion within simulator capabilities for the flying tasks to be investigated.
