 was the first Avro aircraft type to be built in any quantity.The aircraft was first flown on 3 March 1912 by Wilfred Parke, and while top speed and rate of climb did not meet expectations, the aircraft excelled in every other way.However, its performance was not up to Roe's expectations, and a second example was built, modified to take the much lighter 50 hp (37 kW) Gnome air-cooled rotary engine.
