| The design resulted from the Brabazon Committee's Type II design, calling for a small sized, medium range pressurised aircraft to fly its less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).[1] British European Airways (BEA) was involved in the design and asked that the aircraft carry 32 passengers instead, but remained otherwise similar. During development, Vickers advocated the use of turboprop power, believing piston engines to be a dead end in aviation. The Brabazon committee was not so convinced, but agreed to split the design into two types, the Type IIA using piston power, and the Type IIB using a turboprop. Vickers won the IIB contracts, while the IIA was the Airspeed Ambassador. forex trading strategieslego | |
