The first of the two-seaters was designated 519A to reflect its modifications. The second two-seater, however, was so different that it received a completely new number from Avro - 522 - and featured new wings with both upper and lower wings of equal but greater span, in the hope that this would rectify the type's poor climbing performance.
Never used operationally, all four were used for flight testing with the last still in service in April 1917.
There are some indications that the Avro 522A formed part of the equipment of 2 Squadron, Royal Canadian Air Force in the 1920s.
