delivered at the end of 2010. Design The Fokker 50 is a twin turboprop-powered airliner. It was based on the earlier highly successful Fokker F27 Friendship, specifically the stretched F27-500 model. Structurally, the Fokker 50 owes much to the F27; basic construction of the fuselage, wings and empennage, which made extensive use of composite materials, hot-bonded structures and anti-corrosion treatments, remained mainly unchanged between the two aircraft apart from the strengthening of various sections where required. There were some changes made to specific areas of the aircraft, such as the wing being equipped with upturned ailerons and wingtips that effectively acted as wing endplates or winglets, it was also fitted with a larger number of smaller windows in the fuselage and a new two-wheel nose gear configuration, the latter enabling stable operations under uneven crosswind conditions. Perhaps the most major design change from the preceding Fokker F27 was the choice of engines used for the Fokker 50. The original Rolls-Royce Dart turboprop engines that had powered various marks of the F27, which had broadly provided between 1,268 and 1715 kW (1,700-2,300 hp), were replaced by a pair of more fuel efficient Pratt & Whitney Canada PW124 powerplants, each capable of generating , which drove sets of six-bladed Dowty Rotol propellers. These slow-turning propellers, along with other measures such as vibration absorbers, eliminate the need for active noise control systems while providing an average cabin noise level of 77 dBs. The Fokker 50, unlike the F27, was furnished with a glass cockpit which incorporated an electronic flight instrument system and an automatic flight control system, the latter being certified for conducting Cat II approaches. The flying controls include a unique single lever that is capable of controlling both engine power and actuating the variable-pitch propellers, reducing complexity and pilot workload. The cockpit also features a three-stage integrated alerting system that issues warnings to the flying crew. The Fokker 50 can carry up to 62 passengers over a range of at a typical speed of , a increase over the Fokker F27. Typical passenger seating arrangements range from 46 to 56 passengers, which includes overhead bins and a relatively wide central aisle. The airliner features four external doors along with integral airstairs, which enables quicker turnaround times through the faster egress and boarding of passengers and crew alike.
