The case for twin- versus single-turboprop light transport aircraft is being forcefully argued by Vulcanair, which is relaunching its Viator aircraft here at the Dubai airshow. Convinced that the total fuel burn of two Rolls-Royce 250 B17C engines flat-rated at 328 shp is comparable to that of a larger single turbine in the 600-shp range, the Italian manufacturer believes that performance and safety will tip the scales in its favor.
BA609–The Bell Agusta BA609 tiltrotor program is progressing on schedule. On July 13, the second BA609 test aircraft (S/N 60002) performed its first ground run at AgustaWestland’s facility in Cameri, Italy. First flight of this aircraft is pending. S/N 60003 is also at the AgustaWestland facility in Cameri and S/N 60004 is on the assembly line at Bell’s plant in Fort Worth, Texas.
According to Vulcanair director of sales Remo De Feo, the VF600W Mission is still an active program, though it has been “severely delayed due to a number of factors.” These include a lack of funding to continue planned development of the turboprop single and several unplanned modifications that set back the flight-testing program.
