During 1941, Avro elected to begin development of a new civil-orientated transport aircraft. In the midst of an uncertain stage of the Second World War, Britain's aircraft industry was preoccupied by urgent wartime demands, not only to produce military aircraft, but to design increasingly capable models as well. The company's decision to embark on this venture was considered to be ambitious, especially as the development project operated with no official backing early on. The project may well have been influenced by a shortage of transport aircraft, as well as by the formation of the British Overseas Airways Corporation (BOAC), in 1940, to run all of the nation's overseas civil air routes. However, according to aviation author Donald Hannah, there was little incentive and few materials available for the construction of transport aircraft, it was impossible to predict when the war would end and, thus, when large-scale demand for civil aircraft would return.
