Development

The F.110 was an effort by Farman to produce an artillery observation aircraft normally supplied to the French military by Breguet. Mainly of aluminium alloy construction it was a biplane design with a tailskid landing gear. Powered by a water-cooled Salmson 9Z radial piston engine which was a cause of drag because of the need for a large radiator box under the nose which compounded the already large frontal area of a radial engine.

The pilot and observer had an open cockpit which had glazed panels in the sides and the floor to give the observer a good view. After a first flight in 1921 the Aéronautique Militaire ordered 175 aircraft but due to a lack of experience in the company with aluminium alloy the F.110 suffered structural problems. After some modification only 50 aircraft were delivered and the type was not developed further. The F.110 only remained in front-line use for just over a year.

In 1927 tests were made with the F.115, a F.110 with its aluminium ribs replaced with wooden ones.
