Hertz – the New 60 for Flight Simulation ?

Recent advances in technology have led to the development of out-the-window (OTW) scene generators with unprecedented levels of realism; attainable levels of resolution, database detail, color, contrast, and luminance have significantly increased for flight simulation applications. These aforementioned characteristics describe the static qualities of the image. These characteristics, and other factors, also affect the dynamic qualities of not only the out-the-window scene, but also the overall performance of the simulator. Aspects of simulator performance affected by update rate will be discussed.
