Modern civil aircraft generally use electronic flight controlsystem (EFCS), which provide an electronic interface between pilot’s controls and control surfaces, generating the actual surface commands for control about all three airplane axes. The EFCS was required to meet the standards of the handling qualities rating method (HQRM). This unit is a space model of the EFCS Test/Failure Identification Panel control panel. The controls allow specific tests to be initiated and fault codes to be read out.
This unit also bears a green Dymo label marked 25/032

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.
