Evaluating an objective method for motion cueing fidelity

The relationship between the motion fidelity of a flight simulator and pilot handling quality was investigated through a series of pilot-in-the-loop simulations. The phase margin of the aircraft-pilot system during a high gain tracking task was measured while varying the gain and filtering parameters of the motion cueing algorithm, and then compared with Advani-Hosman’s criterion of motion fidelity. Although the results of the simulation are limited to only two axes of the six degrees of freedom, and limited by some hardware limitations, the results partially support the suitability of the criterion of quantifying and qualifying flight simulator motion cueing system.

The NAL's half dome type display system for the flight simulator and its application

A visual sense is an important information source for aircraft pilots. In a modern flight simulator, the image made by computer graphics is used as a visual information. Several equipment which artificial visual information are used as a flight simulator visual system. First, we present display systems for a flight simulator. Next, the half dome type display system which is installed to the National Aerospace Laboratory is explained. Finally, the evaluation results and its application is described.
