[edit] History

The Fokker 50 was designed after sales of the Fokker F27 Friendship, which had been continually in production since 1958, were beginning to decline by the 1980s. Fokker management, notably Frans Swarttouw, decided that an aircraft with aerodynamic and electronic updates from both the Fokker F27 and the Fokker F28 (the short-range twin jet for 85 passengers) was sensible. Design of the Fokker 50 started in 1983.

Certification of the Fokker 50 (initially known as the Fokker F27 Mk050 or Fokker F50) by the Dutch aviation authority RLD was successfully completed in 1987 after four years of design review and flight testing. First delivery was made to DLT of Germany. Production ended in 1996 after the Fokker Aircraft Company went into liquidation. By the end of the program, 213 Fokker 50s had been produced. In 2005 a majority of these were in operational service and in August 2006 a total of 171 Fokker 50 aircraft remain in airline service. Major operators include: Malaysia Airlines (10), Denim Air (12), KLM Cityhopper (16), Skyways Express (18) and VLM Airlines (19). Some 27 other airlines also operate smaller numbers of the type.^[1]

[edit] Design

The Fokker 50 was based on the stretched F27-500 airframe, but with a larger number of smaller windows in the fuselage and a two-wheel nose gear.

Basic construction of the fuselage, wings and empennage (tail) remained unchanged apart from strengthening the various sections where required. The wing was equipped with upturned aileron and wingtips, effectively acting as wing endplates or winglets.

The major design change from the Fokker F27 was in the engines, and in equipping the aircraft with an electronic flight and engine-management system. The original Rolls-Royce Darts in various marks of basically 1700 to 2300 HP was replaced with two more fuel efficient Pratt & Whitney Canada PW124 powerplants of max 2500 HP each, driving a 6 bladed Dowty Rotol propeller.

Compared to the Fokker F27, the Fokker 50 can carry around 50 passengers over a range of 2000 km at a typical speed of 530 km/h, a 50 km/h increase over the Fokker F27.
