The four unequal sisters

As a further development of the seaplane Avro 510 was the beginning of 1916 for the Royal Navy Air Service ( RNAS ), the British naval aviators who developed Avro 519.

In the first two delivered 519 These were single-seat bomber with foldable wings and the already known from earlier Avro patterns chassis with the characteristic skid between the wheels of the main landing gear. The large rudder corresponded in shape to that of the Avro 504B models. Was powered by a 150 -hp ( 152- hp ) Sunbeam Nubian engine.

Later, two more aircraft were delivered, appointed by the Royal Flying Corps ( RFC). This two-seater version with a modified suspension without skid was designated as 519A and was equipped with a 250 -hp ( 253.5 -PS) - Sunbeam engine.

Each of the four machines was ultimately unique. Thus, in the first machine, the condenser was installed to the side of the hull, in the second, however, the cooler layers above and below the motor; in this arrangement, the upper radiator but the pilot took the view, also this machine was known for very poor climb performance.

Exotic Avro 522

To eliminate this drawback, was changed in the fourth machine, the wings - upper and lower wing now had to increase the buoyancy of the same length, the total span was lower than for the other machine.

Curiously, the type designation 522 was attached, although it was officially listed as Avro 519A on this machine.

This fourth aircraft was launched on November 1, 1916 by Hamble to tests by the military, where it remained until April 1917.

There is evidence that all four machines were tested in Farnborough ( The large Avro ) were known there as "The Big Avro "; about their further fate is not known.
