On 1 January 1979, BAF transferred its entire scheduled operation including associated aircraft and staff to British Island Airways (BIA). Following British Airways's decision to withdraw from its loss-making regional routes and to retire its Vickers Viscount turboprop fleet, BAF acquired the entire 18-strong fleet along with the spares inventory during the early 1980s. This acquisition made it the world's largest Viscount operator at the time. As a result of the changes the airline underwent in the late 1970s and early 1980s, BAF mainly concentrated on leasing, charter
Turboprop civilian aviation is in small commuter aircraft, where their greater power and reliability offsets their higher initial cost and fuel consumption. Turboprop-powered aircraft have become popular for bush airplanes such as the Cessna Caravan and Quest Kodiak as jet fuel is easier to obtain in remote areas than avgas. Due to the high price of turboprop engines, they are mostly used where high-performance short-takeoff and landing (STOL) capability and efficiency at modest flight speeds are required. Turboprop engines are generally used on small subsonic aircraft, but the Tupolev Tu-114 can reach 470 kt (870 km/h, 541 mph). Large military and
