Colour Vision Requirements in Different Operational Roles in the Royal Air Force
Abstract
A study into the importance of colour vision in the various operational roles of the Royal Air Force has been carried out. It is considered that good colour discrimination, although playing a valuable part in the total process of visual perception, is not of paramount importance. It would be possible by altering the present chromaticities of red and green signal colours to admit for all aircrew duties, expect those of close air support, more severe grades of red green defective than at present. The pseudo-isochromatic plates provide a simple and rapid method of detecting even minor anomalies of colour vision, and should be retained as the initial examining procedure. With present standards, the lantern is the best 'trade test' for grading colour defectives as fit or unfit for aircrew duties. Should standards be lowered, it would be necessary to supplement the lantern with a quantitative test which should be related, if possible, to the role envisaged for the candidate.
