ABSTRACT:
An environmental fog/rain visual display system for aircraft simulators comprising a combination of electronic and mechanical integrated elements which operate together to produce realistic environmental conditions that would actually be encountered by a pilot flying an aircraft. The electronic elements of the system include a real time digital computer, a calligraphic color display which simulates landing lights of selective intensity, and a color television camera for producing a moving color display of the airport runway as depicted on a model terrain board. The mechanical simulation elements of the system include an environmental chamber which can produce natural fog, nonhomogeneous fog, rain and fog combined, or rain only. The environmental chamber is positioned between the color scene produced by the television camera and calligraphic color display and the windscreen of the teaching aircraft cockpit. Thus, a pilot looking through the aircraft windscreen will look through the fog and/or rain generated in the environmental chamber onto a viewing screen with the simulated color image of the airport runway thereon, and observe a very real simulation of actual conditions of a runway as it would appear through actual fog and/or rain. The density of the fog in the environmental chamber can be rapidly increased or decreased to simulate the fog gradients typically experienced at the time of takeoff or landing.
