Vulcanair bets its Viator that one big one beats two
The case for twin- versus single-turboprop light transport aircraft is being forcefully argued by Vulcanair, which is relaunching its Viator aircraft here

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.
