Farman F.110

The Farman F.110 was a French two-seat artillery observation biplane designed and built by the Farman Aviation Works. Farman wanted to supply the French military with an observation aircraft of a kind that Breguet normally provided, and built it mainly of aluminium alloy around a biplane layout with a tailskid undercarriage. It was powered by a water-cooled Salmson 9Z radial piston engine of about 260 horsepower, whose large radiator box under the nose added drag. After its first flight in 1921 the Aeronautique Militaire ordered 175 aircraft, but the company's lack of experience with aluminium alloy led to structural problems and only 50 were delivered. The type saw front-line use for just over a year and was not developed further, although a wooden-ribbed variant, the F.115, was tested in 1927.
