In 1986 GEC Avionics was asked to design a HUD to replace the AN/APG-59.60 gunsight (manufactured by Westinghouse and the American Cystoscope Makers Inc., New York, USA.) on the venerable F-4J. The F-4 had a busy cockpit with an Optical Sight integrated on top of the Command Indicator Radar Display. The Gunsight had only a reticle and a pipper with moveable tabs and it was thought that a HUD would be of benefit. However, the normal arrangement with the depth of the fold mirror would not allow the unit to be positioned sufficiently aft to give the pilot a decent field of view. The Company’s solution was to set the Radar Display forward and fold the image around to a new screen located immediately on the left of the HUD. This in turn allowed the HUD to be positioned up to the ejection line to give the optimum field of view. A prototype of this design was constructed and fitted to an F-4 but a contract was never forthcoming. This is a space model used for marketing or for cockpit fit test.

The RAA contains a number of models of equipment and aircraft. The equipment models were used as a marketing aid and often to ensure that the production unit will fit in the space; this was particularly true for Head Up Displays. Such equipment models will have minimal or no functionality. Models might  just be used as weighted units or as cockpit lighting evaluation units. The HUD used on the YF-16 was of the correct weight and envelope but only mounted the Spin 'chute button (a feature only required for the early test flights). Many of these models were made by professional model makers from the original drawings and could be quite expensive; alternatively the real hardware would be used.

The aircraft models range from the simple small scale kits to quite large display items. The large model aircraft were often a marketing tool from places like Airbus or Boeing but may be found in Boardrooms or Reception areas wheras the small models may be given as a visitor handout. Those models made from kits have largely been brought in from home but are useful to illustrate the platform alongside the equipment. The large models will be hugely expensive.
