General Characteristics

The Avro 504 is one of the most famous and longest-serving aircraft in British aviation history. First flown in 1913, the Avro 504K became the definitive production variant, introduced during World War I primarily as the standard military trainer for the Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS). The ‘K’ designation signifies its unique universal engine mount, which allowed it to be fitted with various types of rotary engines (like the Le Rhône, Clerget, or Gnome Monosoupape) to cope with wartime engine shortages. Over 8,000 were built during the war, and it continued to serve as the RAF’s primary trainer well into the 1920s, with surplus models used globally for joyriding and civilian training for decades.
