The SAE Committee A-20 on aircraft lighting requested that the Air Force review the need for blue filtered white lighting because many manufacturers have had a difficult time meeting the present specifications. Nineteen pilots flew filtered and unfiltered panels in the T-38, and their preference was strongly in favor of the blue filtered white lighting. Accordingly, it is recommended that the blue filter be retained. Author
