In aircraft design the mock-up has an important place. In these modern times they are often made using plastics but in the VC10 days wood was the material of choice. The purpose of the mock-up is to transfer the ideas from the drawing board to the production line, and as such it is an important aid to designing an aircraft. It enables the engineer to plan in three dimensions, and provides a check on the layout of the thousands of integrated components which make up an aircraft. Besides this, it also serves as a demonstration of layout possibilities for the customer. Sometimes it is only in the mock-up stage that important decisions can be made. Specific dimensions in cabins, galleys and cockpits can easily be set on a drawing but until you can find out for yourself if a cupboard is set at the right height you cannot be sure if your design will really work when used on a day-to-day basis. Because of this the mock-up can get quite crowded as it is being built with many different designers wandering about, checking on the feasibility of their ideas or complaining about someone else's air-conditioning ducts positioned just where they wanted to put a box full of electronics. As an example, the VC10 mock-up featured a fully equipped flight engineers station which was used for night lighting trials amongst other things.

Besides the complete mock-up that is pictured on this page, a separate mock-up was built of the freight door for the RAF version of the VC10. This was probably used to test the size of the door against many different types of military cargo that the VC10 was destined to carry.

The mock-up for the VC10 was set up, together with the 1-11 mock-up, in the mock-up hangar at Brooklands, or to use the official terminology: British Aircraft Corporation - Weybridge division. This mock-up hangar was a wartime structure that is positioned on what used to be the 'Finishing Straight' of the pre-war Brooklands racing circuit. This hangar is still in existence as the sole survivor on the Brooklands site. The ex-mock-up hangar is now the main hangar for the aircraft collection of the Brooklands Museum, and as such provides shelter to: Wellington R for Robert, the Vickers Vimy replica, Harrier G-VTOL and several other aircraft.
