The '''Farman F 400''' was a 1930s [[France|French]] three-seat cabin high-winged monoplane which was designed and built by [[Farman Aviation Works|Farman]].

==Design and development== The Farman series "400" was a revolution for its builder because it had a thin, cantilever-constructed, high wing, with round edges, which could be dismounted for better storage and transportation.

The aeroplane had mixed construction. The [[fuselage]] was made of steel tubes, while the wings had a wood frame. The fuselage and the wings are both covered with [[plywood]].

This version, the '''Farman F 402''', had a [[Lorraine (company)|Lorraine]] 5 Pb 5-cylinder [[radial engine]] of {{Convert|110|HP|abbr=on}}, but the plane in the picture had it changed for a 9-cylinder radial engine [[Salmson]] of {{Convert|120|HP|abbr=on}}.

The F 402 has an unusual feature, which is that the control stick hangs from the ceiling of the cockpit, and the rudder control is a vertical steering wheel.

The fuel tanks, which are placed inside the wings, have a capacity of 200 liters.

The [[landing gear]] structure is constructed of iron bars, which allows this plane to land "hardly" in short space.

This aircraft served, among other countries, in [[Spain]], during the 1936-1939 [[Spanish Civil War|civil war]], on both sides.
