EVALUATION OF EXPERIMENTAL POINT SOURCES AND TRANSPARENCIES FOR HELICOPTER HOVERING FLIGHT SIMULATION DEVICE 2FH2

摘要

The visual display produced by the point light source and transpar¬ency originally furnished for Device 2-FH-2, an experimental helicopter hovering flight simulation device, and the visual display produced by a new light source and transparency for that device were evaluated by pilots. These evaluations were then compared to determine the relative merits of the original set and the new set of components. An appraisal of the useful¬ness of such a device for training was obtained also.nThe improved resolution obtained with the new light source is pref¬erable to th2 greater brightness of the original one. The photographic techniques used in preparing the new transparency result in a more real¬istic display than that obtained with the wholly hand-decorated original transparency.
