Development
The Lakes Water Bird was built for 1911 E.W. Wakefield, of the Lakes Flying School, Windermere by A.V. Roe, who would build aircraft to the designs of individual customers. It was built as a landplane with the intention of converting it to a seaplane once testing was complete. Wakefield had been interested in water-borne aircraft since 1909 and had performed experiments with different float designs towed at speed across Lake Windermere. Unsticking problems persisted until he visited Henri Fabre in France and got useful advice on float design. The 12 ft (3.66 m) long float for the Water Bird followed Glen Curtiss' three-step float and was built by boat builders Borwick of Bowness-on-Windermere using mahogany reinforced with metal strips and canvas covered by local.
Avro built the aircraft in Manchester, transporting it to Brooklands for its first flight on 19 May 1911. It was a two-bay seat pusher biplane with wings of unequal span. The outer half of each upper wing carried a pair of ailerons; the larger inner one had a semicircular trailing edge extending well behind the wing trailing edge. Bamboo outriggers fore and aft of the wings supported leading elevators and tail surfaces plus rudder. Both elevator and rudder were operated by bamboo pushrods. Power was provided by a 50 hp (37 kW) Gnome 7-cylinder rotary engine driving an 8 ft 6in (2.59 m) propeller.
After testing as a landplane at Brooklands in May 1911, the Water Bird was brought to the Hill of Oaks on Windermere and the float fitted in place of the wheeled undercarriage. A pair of cylindrical floats was mounted below the wing-tips for lateral stability on the water. The successful first flight was on 25 November 1911, with ex-Avro school pilot H. Stanley Adams.

Famous quotes containing the word development:
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the child’s mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
