Many PPRuNers will think of aircraft like the 250 kt Jetstream or the 300 Kt Hercules when they think turboprop - or will summon up claustrophobic high winged turbine engined airliners like the F27 or Dash 8.
But turboprops don't have to be like that, do they?
The Tu-114 (the civvy 'Bear') could reach 490 kts, and cruised at 436 kts.
The aircraft had a ceiling of just under 40,000 ft, and a range of almost 5,000 miles.
And that's near A340 levels of performance from a turboprop airliner with its feet firmly planted in the 1950s - what could be achieved with modern aerodynamics, modern engines and modern props?
Better than the 460-485 kt A400M, I'll be bound.
