The FK-Leichtflugzeuge FK-14 is a product of B&F Technik Vertriebs GmbH.
Production of the airframes takes place in Krosno, Poland; assembly of
the airframes and the final production of the aircraft in the factory in
Speyer in Germany. Otto Funk (=FK) designed in 1959 on behalf of Heinkel
in Speyer the complete metal glider Greif 1a (FK1). This was the start
of a range of light aircraft. Otto Funk started in 1984 with the
development of a light aircraft: the FK6. With this design the UL-market
was entered. The break-through on this market was the introduction of
the FK9 in 1989, a combined design of Otto and his son Peter. To build
the FK9 Peter Funk and Dirk Breitkreuz founded in 1990 the company B&F
Technik. The FK14 Polaris is a combined design of Otto and his son
Peter. Development of this high-performance cruiser started in 1997.
Otto Funk developed the main wing structure with its special Fowler flap
system in co-operation with the University of Stuttgart using its
laminar wind tunnel. The rest of the air frame was designed by Peter
Funk, whereby standard parts of the FK9 Mk3 were used as far as
possible. The construction of the Polaris began in 1998 and the
prototype of the FK14 was flown first in May 1999. The FK14 is
constructed in a mix of aluminium and fibreglass composite materials.
The cockpit area is built of a crash-resilient tubular steel frame. At the EAA AirVenture 2007, Cirrus Design Corporation, Duluth, Minnesota, US,
launched the Cirrus SRS (or SR Sport) light sport aircraft (LSA). The
SRS is based on the B&F FK14 Polaris.
