"The effects of pure red and low color temperature white flood lighting upon completely dark adapted visual thresholds have been determined. The red light was adjusted to brightness levels which pilots have been found to use as the minimal, normal, and maximal levels for night flying. For each brightness level of the red light, a brightness was found for the low color temperature white light at which aircraft instruments were equally legible under the two lighting systems. Both a simulated instrument panel and a pure white panel were used as viewing panels. Six subjects were tested under each lighting condition. A higher brightness proved necessary with the low color temperature white light than with the pure red light in order to attain equal legibility of instruments. Both lighting systems at all brightness levels caused small increases in visual thresholds above the completely dark adapted state. When the simulated instrument panel was illuminated at the normal brightness level, thresholds after viewing low color temperature white light were 0.15 log micro-microlamberts above thresholds after viewing pure red light. This value defines the approximate sacrifice in dark adaptation which would be made if white lights, operated at low voltage, were substituted for red lights in flood lighting aircraft instruments. The white lighting would also be more visible to dark adapted enemy observers. However, the white lighting system would make colors in the cockpit appear more natural, which would facilitate such tasks as map reading. When operated at normal voltage, the white lighting system could also provide high intensity illumination for special purposes such as thunderstorm flying, very high altitude daytime flight, and simulated instrument flying with the amber hood and blue goggles."--Abstract.

"The general problem of designing charts for legibility under red cockpit light is examined in the context of related problems. The characteristics of charts and the techniques for presenting information on them are analyzed and evaluated in relation to possible methods for improving red light legibility. Several lines of research carried out under this project are reviewed, and two experimental charts are exhibited and descibed. Methods for improving red light legibility, within the framework of present size and space limitations and production techniques, are summarized."--Abstract.

"An important factor in the design of equipment for maximum efficiency of human operation is the design, illumination, and arrangement of visual displays which provide information to the human operator. This report provides a compilation of general human engineering recommendations and presents some of the supporting data which should aid the engineer in providing the most satisfactory visual presentations of information. The report is divided into seven chapters entitled: mechanical indicators, warning devices, cathode-ray tubes and signal coding, printed materials, instrument panel layout, lighting, and visual detection and identification. Liberal use is made of pictorial, graphic, and tabular presentations to illustrate the data and design recommendations. A table of contents, subject index, and a selected bibliography are included as an aid to the user."--Abstract.
