The Avro 519 was a double-decker - airplane of the British manufacturer Avro .
General
The four dissimilar sisters
As a further development of the seaplane Avro 510 , the Avro 519 was developed in early 1916 for the Royal Navy Air Service (RNAS), the British naval aviators .
In the first two delivered 519 these were single-seat bomber with foldable wings and the well-known already from earlier Avro patterns suspension with the characteristic runner between the wheels of the main landing gear. The shape of the large rudder corresponded to that of the Avro 504B models. A 150 hp (152 hp) Sunbeam Nubian engine served as the drive.
Two more machines were later delivered, ordered by the Royal Flying Corps (RFC). This two-seater variant with a modified chassis without skid was designated as the 519A and was equipped with a 250 hp (253.5 hp) sunbeam engine.
Each of the four machines was ultimately unique. In the first machine, the radiators were installed on the side of the fuselage, in the second, however, the radiators were above and below the engine; In this arrangement, however, the upper cooler prevented the pilot from seeing, and this machine was also known for very poor climbing performance.
Exotic Avro 522
To remedy this shortcoming, the wings of the fourth machine were changed - the upper and lower wings were now the same length to increase lift, and the overall wingspan was smaller than that of the other machines.
Strangely, the type designation 522 was attached to this machine , although it was officially listed as Avro 519A .
This fourth aircraft was brought to Hamble for military tests on November 1, 1916, and remained there until April 1917.
There is evidence that all four machines were tested in Farnborough and were known there as "The Big Avros" (The Big Avros); nothing is known about their further fate.
