The Avro 503 was a double-decker - airplane of the British manufacturer Avro .
General
After the experience with the 501 , a machine with slightly larger dimensions, also equipped with the 100 hp (101.4 hp) Gnome engine, was developed at Avro. This aircraft was designated Avro Type H . Like the 501 , the Type H was designed as a seaplane , equipped with a central float and support floats at each end of the wing. When designing the machine, Avro paid particular attention to the possibility of simple and quick dismantling of the aircraft.
The first take-off took place on the River Adur on May 28, 1913 , and the following day Avro test pilot FP Raynham made the first landing at sea near Brighton . Since one of the swimmers was damaged at the next start, the swimmers in the front area were reinforced.
On June 12, 1913, a one-hour demonstration flight took place over Brighton, Raynham took a passenger with him and achieved an attractive climb despite the relatively high weight.
The machine, now known as Avro 503 , was acquired by the German Navy at the end of June, and on September 3, 1913, under its pilot Lieutenant Langfeld, it was the first aircraft to cover the Wilhelmshaven - Helgoland route .
Another 503 was ordered by the Peruvian government, but it can be assumed that delivery did not take place due to the outbreak of the First World War .
Avro built three more 503s for the British naval aviator of the Royal Naval Air Service , all machines were converted to land planes by September 1914. A 503 crashed on August 11, 1915, the last of these aircraft was in service until January 1916.
