The effectiveness of two types of steady and flashing lights as escape hatch indicators for submerged helicopters was compared. Measurements were taken in moderately and highly turbid water. Response time was faster to the steady lights, and they were more accurately localized. Pairs of steady lights appeared to have some advantage over single lights, but this was not true for flashing lights. Subjects found it very difficult to discern how many different locations were being illuminated.
比较了两种类型的稳定光和闪烁光作为水下直升机逃生舱口指示器的有效性。在中度和高度浑浊的水中进行了测量。对稳定光的反应时间更快，并且它们的定位更准确。成对的稳定光似乎比单个光有一些优势，但对于闪烁光并非如此。受试者发现很难辨别有多少不同的位置被照亮。
