Effects of Compression-Induced Distortion of Graphical Weather Images on PilotPerception, Acceptance, and Performance

摘要

The Graphical Weather Service (GWS) is a data link application that will providenear-real-time graphical weather information to pilots in flight. To assess the effect of GWS. as well as to aid in the proper design, implementation and certification of the use of GWS in aircraft, two human factors studies have been conducted. The second study conducted (Phase Two) is the topic of this report. Phase Two was conducted to determine the maximum level of compression-induced distortion that would be acceptable for transmission of weather images to the cockpit.
