Gaseous-discharge lamps for airplane lighting service

J. T. Gove (Los Angeles, Calif.): Fluorescent lamps now are used for instrument lighting only on Army aircraft and on Naval aircraft of older design and not on all military aircraft as implied in this paper. On Naval aircraft of new design, red indirect lighting is used for instrument panels, and red lighting also is used for general cockpit illumination and for chart-board illumination. The reason given for the changes to red lighting is that it is a means for providing better dark adaptation of pilots' eyes. Whether red lighting or fluoroescent lighting best accomplishes this purpose is apparently a controversial issue.
