Construction

Fokker F.VII is a passenger, mixed-air high-wing aircraft. The canvas fuselage. The cover is made of duralumin sheet in front of the pilot's cabin.

A simple, wooden, two-girder flap, covered with birch plywood and canvas, had a lot of elongated ailerons at the ends. The central part of the lobe housed a 720-liter fuel tank.

One engine was placed in the nose of the fuselage, in versions F.VIIa / 3m and F.VIIb / 3m, two more engines were mounted under the wings on the booms. Behind the engine in the fuselage there was a covered pilot and mechanic's cabin, followed by a passenger compartment connected to the crew's cabin by a passage. The passenger compartment was equipped with glazed windows on both sides of the fuselage and had 8-10 passenger seats. A door led into the passenger compartment from the fuselage, through which the flight crew also entered.

Classic set-up, controlled by means of lines extending outside the aircraft cover to the controls in the hull.

Classic landing gear, solid, with tail skid.
