DESCRIPTION

This Fox C-22 is a strut-braced high wing airplane powered with a Rotax 462 two-cylinder, 2-stroke, water-cooled engine. The engine is equipped with a starter and generator for 12-volt operation. The 12-volt storage battery supplies current for starting and identification lights. The battery is located in the nose of the aircraft

A single control stick is situated between the seats, with the throttle situated on the outer front sides of both seats. The flap handle is situated in the roof between the two seats. The hydraulic brakes, situated on the control stick, control both wheels simultaneously. The wide tread landing gear with rubber cord shock absorbers and the steerable nose wheel provide stability and easy manoeuvring on the ground.

 The instrument panel contains the flight instrument, engine instruments, and hand held radio bracket. The intercom system is located on the floor at the panel base.

The two 25 litre fuel tanks are situated behind each seat. There are no fuel cocks in the system. Fuel pressure is supplied via a mechanical fuel pump situated to the left, rear of the engine. An auxiliary electric fuel pump is also fitted.
