The Avro 510 was a two-seat racing seaplane designed by Avro to compete in the 1914 Circuit of Britain Race. It was a conventional two-bay biplane of greatly uneven span equipped with two large central floats and two outriggers. The race was called off at the outbreak of the First World War but the British Admiralty was aware of the type and ordered five examples with modified floats and tail.
Made by Avro.
Avro 510 is the predecessor of the Avro 519.
