TEST AND EVALUATION OF A DAYTIME COCKPIT FOG SIMULATOR

An evaluation was conducted at the National Aviation Facilities Experimental Center CNAFEC), Atlantic City, N.J., to determine the suitability of a Daytime Cockpit Fog Simulator to accurately and realistically simulate Category II and Category III weather conditions to the pilot during flight approaches. Thirteen pilots, using a DC-7 aircraft, participated In the program. The fog simulator was evaluated during atmospheric meteorological visibilities ranging from 1 1/2 to over 12 miles. Technical data, as well as completed pilot questionnaires, comprised the data analyzed. Although the simulator shows merit insofar as projecting realism, a redesign of the unit is necessary to correct deficiencies in various optical, electronic, and mechanical areas.
