The Blind Landing Experimental Unit (BLEU) of the Royal Aircraft Establishment (RAE) was formed at RAF Woodbridge and RAF Martlesham Heath during 1945 and 1946. It was a multi-disciplinary unit, drawing staff from the RAE, Farnborough and the Telecommunications Research Establishment, Malvern (TRE).[12] The terms of reference were that the unit "will operate as a satellite of the RAE and will be responsible for the development on blind approach and landing of RAF, Naval and Civil aircraft".[13] Research during the first few years at BLEU led to the conclusion that a promising approach to blind landing would be a fully automatic system, and produced a definition of the requirements for such a system, later designated Autoland.
