Thesis (Ph.D.)--Arizona State University, 2003.

Despite significant advances, state-of-the-art image projectors still lack the ability to display object detail equivalent to a 20/20 visual acuity capability. Unfortunately, for proper close-in air combat training in a flight simulator, this level of detail is necessary if a pilot is to accurately determine the orientation of another aircraft at realistic ranges. This investigation evaluates a possible interim solution to this problem that could be implemented until projectors are developed that can provide adequate resolution. The research methodology involves enlarging the “enemy” aircraft by various amounts as a function of distance-resulting in an aircraft that still always gets smaller as it moves farther away, but just not as quickly as a “non-enlarged” target. The results from 20 male F-16 pilots provided the distances where the orientation of aircraft in the simulator could be determined as well as similar aircraft under “real-world” conditions. By using these distances, it was possible to determine the amount of magnification needed to identify necessary details of the simulated aircraft at the same distances as they are under “real-world” conditions. The final product is a magnification curve that can be used to modify how the simulated target changes in size as a function of distance. Results seem to indicate that performance in the simulator might be enhanced to match real flying conditions without unacceptably (or perhaps even noticeably) altering the size of the target. These results should be applicable (with minor modification) to many other aircraft and perhaps ground targets as well. Furthermore, it is anticipated that application can be made beyond flight simulation to other types of simulation where performance is also currently inhibited due to lack of display resolution.Subjects--Topical Terms:
