Avro 504

The Avro 504 was a British First World War biplane aircraft built by the Avro company. Designed as a light reconnaissance aircraft, it proved adaptable and versatile, eventually serving in numerous roles including bomber, trainer, and even as a fighter. It was one of the first aircraft to be used in combat, making its debut in August 1914 with the Royal Flying Corps.

The aircraft was powered by a variety of rotary engines, typically in the 80-110 horsepower range. Several different variants were produced throughout its service life, with modifications focusing on improved engine performance, armament, and training capabilities. Notable variants include the 504A, 504B, 504C, 504K, and 504N.

The Avro 504's most significant legacy lies in its widespread use as a training aircraft. After the First World War, surplus 504s were readily available and affordable, leading to its adoption as a primary trainer by numerous air forces and flying schools around the world. Its simple design and docile handling characteristics made it an ideal platform for introducing pilots to the fundamentals of flight. Consequently, the Avro 504 played a crucial role in the development of aviation during the interwar period. Production continued well into the 1930s, and the aircraft remained in service in some capacity until the late 1930s.
