Joint Ministry of Aviation/Royal Swedish Air Force Board experiments to assist in the evaluation of the Head‐Up Display concept have been completed at the Minerva Laboratories, Treforest. Using a fixed based simulator, pilots from the Royal Navy, Royal Air Force and Royal Swedish Air Force were subjected to tests prepared and conducted by personnel from the Institute of Aviation Medicine, Farnborough and Saab at Linkoping, Sweden. The pilots selected for the experiments had little or no experience of using head‐up display equipment. After briefing, each pilot was subjected over a period of 21/2 days to tests of increasing complexity to determine the individual reactions to the differing forms of display symbols which are used in British and Swedish equipment.
