Abstract : Experiments were carried out with the object of determining which of several arrangements might best be used in the exterior lighting of aeroplanes, with particular reference to the phenomenon of autokinesis. The tests were carried out in a dark room with the observers viewing one or more lights at a distance of 2 or 6 meters. In general, a progressive reduction in autokinesis was observed by increasing the number of lights and by placing them at various levels in different vertical planes. This reduction was more rapid at 2 than at 6 meters. Rows of closely spaced lights offer little advantage over single lights placed at extreme points, provided all lights are visible. (Author)
