From Wikipedia, the free encyclopedia
The Avro 547 was a prototype triplane airliner developed in Britain after World War I. It utilised components from the highly successful Avro 504 but added an extra set of wings and a fully-enclosed cabin to seat four passengers. The pilot sat in an open cockpit offset to port. While the prototype flew well, the second example built was substantially modified in order to meet a British Air Ministry requirement for a commercial aircraft. Designated 547A, this version turned out to be slow and unstable in the air and was scrapped after it was damaged in a hard landing.
Despite the performance of its successor, Qantas bought the first prototype in November 1920 for ₤GBP 2,800 with the intention of using it on a route between Charleville and Katherine. The 547, however, proved utterly unsuited to outback conditions and was quickly decommissioned, its fuselage ending its days as a chicken coop in Sydney.
