The original Avro 504 had been designed in 1913 by Sir Alliot Verdon-Roe, and entered the British Royal Flying Corps as a standard Service machine. The aircraft had a top speed of 82 mph. (132 km/h), could climb to 10,000 feet in 19 minutes and could stay aloft for three hours. Early in the war the 504 strafed the enemy and bombed the zeppelin sheds at Freidrichshafen, but it soon became clear it wasn't destined to compete with the faster, meaner planes then being rolled out, such as the Fokker E.III. Because of its ability to operate at the "extreme height" of 13,000 ft (3960 m) it was relegated to the role of anti-zeppelin patrol plane.

It did, however, make an admirable trainer airplane and was developed in this way by Major R.R. Smith-Barry, along with his personal instruction method. In this incarnation it made a significant impact all over the world, and laid the foundations for formal flyer training that would last another 30 years. Ultimately, the Avro 504 was built in Australia, Belgium, Canada, Japan and the USSR, with production continuing until 1933. Estimates vary as to how many were made, ranging from 6,350 to over 10,000.

The advantages that the 504 had over previous trainers were numerous. The Curtiss JN-4, envisaged as a trainer, was difficult to fit with a rotary engine. This was seen as vital to familiarize flying students. To deal with this problem the 504K was introduced in 1917, and sported a new type of universal engine mount which consisted of two bearer plates that could accommodate any sort of engine. The 504K was variously fitted with the 100 hp Gnome B Monosoupape, the 110 hp Le Rhône 9J, and the 130 hp Clerget 9B engine.

Another advantage was the ease with which students and instructors could communicate in the cockpit, thanks to the "Gosport Speaking Tube". It was more robust than the delicate Farman trainer, and more manoueverable than the heavy BE2c. The 504's relatively light weight in comparison to its wing size prevented the plane from dropping dramatically when power was reduced, and the "forgiving" quality of its controls were ideal for training. So too was the skid that could be outfitted under the nose, designed to prevent tipping during landing.

The 504 had the distinction of quite a few "firsts". It was the first airplane to strafe troops on the ground, and the first to run a bombing raid over Germany. It also had the dubious honour of being the first Allied airplane to be downed by enemy ground fire. It was the first airplane to run a commercial bush flight in Canada when it ferried two passengers from Winnipeg to Le Pas, Manitoba in 1920, and the first to make a winter flight to James Bay in 1922.
