The Avro Type D was an aircraft built in 1911 by the pioneer British aircraft designer A.V. Roe. Roe had previously built and flown several aircraft at Brooklands, most being tractor layout triplanes. The Type D was his first biplane.
The Type D was the first biplane design by A.V. Roe. Like his earlier aircraft, the Roe IV Triplane, it was of tractor (aircraft) configuration and had a triangular section ash fuselage, divided in two-halves bolted together behind the cockpit for ease of transportation. The high aspect ratio wings were braced in an irregular three-bay layout, the interval between the pairs of interplane struts increasing from the centre section outwards. Lateral control was by wing warping. The wing was mounted directly to the lower longeron of the fuselage, at the front of which was the 35 hp (26 kW) Green water-cooled engine, with the radiator mounted flat behind it in the direction of travel under the upper wing, between the fuselage and upper wing. Behind this a small coaming protected the passenger, with the pilot sitting behind. The empennage was similar to that of the Roe IV, with a low-mounted D-shaped rudder behind a small rectangular fixed fin and a large triangular tailplane bearing D-shaped elevators. The undercarriage had two forward-projecting skids, each mounted with a pair of wheels on a short axle.
The Type D was first flown at Brooklands on 1 April 1911, piloted not by Roe but by C.H. Pixton, who reported that it was easy and pleasant to fly. This assessment was confirmed a few days later when Lt. Wilfred Parke succeeded in flying it the length of Brooklands on his first attempt at flying an aircraft. On 12 May Pixton flew the aircraft to Hendon to give a demonstration of the aircraft before the Parliamentary Aerial Defence Committee. During this occasion C.R. Samson was taken for a flight as a passenger, and A.V. Roe made his first solo flight in the aircraft. After Pixton had made a number of other flights, in June the aircraft was sold for £700 to Cdr Oliver Schwann of the Naval Airship Tender Hermione. It was sent by rail to Barrow-in-Furness, where Schwann converted it to a floatplane.
