The desired system for general aviation aircraft instrument panel and cockpit lighting should furnish light of adequate intensity and distribution under all conditions of external illumination so that the crew may read instrumentation, placards, check lists, manuals, maps, instrument color coding, and distinguish controls without undue interference with their vision outside of the aircraft. Heretofore, considerable effort has been made to insure night vision adaptation at all costs. Efforts to maintain this adaptation have been based on certain military requirements, night flight involving pilotage and takeoffs or landings using only moonlight or less light intensity. With present navigational methods, adequate airport lighting and aircraft landing lights, night vision adaptation is rarely necessary. Lighting at low illumination levels often creates a compromise in visibility within the cockpit which may cause serious problems as a result of improper map reading, improper fuel selection, etc. Adequate and comfortable lighting should, in most instances, be the primary goal. The dangers of inadequate lighting within the cockpit appear to be greater, at present, than the advantages of maintaining night vision.tion, etc. Adequate and comfortable lighting should, in most instances, be the primary goal.
