The development of the B&F Fk12 Comet, also known as the FK-Lightplanes FK-12 Comet, was associated with the need to create a small two-seat sports aircraft capable of flying at high speeds, but at short distances. Initially, German aviation specialists intended to create a low-wing aircraft, however, in the end they settled on the design of a biplane - its more aerodynamic forms could not only provide a high travel speed, but in fact, made it possible to withstand both high positive and negative overloads.

Experts do not exclude that not the last word in the popularity of the B&F Fk12 Comet was played by its design, which meets most modern requirements, and at the same time is quite practical in terms of technology when creating an aircraft.

The B&F Fk12 Comet aircraft has a small size - its length is only 5,54 meters, with a wingspan of 6,74 meters, which in turn reduces drag during flight and increases the maneuverability of the aircraft, which is very typical for a sports aircraft.

The B&F Fk12 Comet can accommodate only two people, however, in fact, this did not play on the popularity of the aircraft - during the period from 1997 to 2011, 102 aircraft of this model were built, which, with limited operational properties, demonstrates a fairly high his interest for customers. In addition, due to the peculiarities of the aircraft design, the transportation of any cargo on it is not possible, which in turn is one of the negative aspects of this model.

The power plant of the B&F Fk12 Comet biplane is represented by one Rotax 912 ULS four-cylinder piston aircraft engine capable of developing a thrust of 100 hp, which is not enough for a sports aircraft. Nevertheless, the maximum flight speed of this aircraft is about 215 km / h, which, with high maneuverability, meets most of the requirements.

Due to the limited maximum following distance, and the flight range of the aircraft is only 650 kilometers, the aircraft is practically not used for passenger transportation, although at the initial design stages of this aircraft, this possibility was envisaged by aviation engineers from the aircraft building company "B&F Technik Vertriebs gmbh".
