The cooperative Navy/Air Force project described is aimed at the problem of image-flutter encountered when visual displays that present computer generated images are used for the simulation of certain flying situations. Two experiments are described which extend laboratory work on delay compensation schemes to the simulation of formation flight in the research device, Advanced Simulation for Pilot Training (ASPT). Both studies were geared to determining break-points for low-pass filters that would allow adequate flying control performance and provide an acceptable display. One experiment represented a factorial combination of settings of the display filters and the non-visual cues of aircraft motion provided by the g-seat and motion platform, and the second represented a simple comparison of filter settings. Both studies indicated that, at least for formation flight, there is a range of filter settings which will not adversely affect flight control and will adequately suppress visual flutter. This range represents half-power settings for the filters of three-fourths to one Hertz. (Author/CMV)
