BAC One-Eleven BAC One-Eleven The British Aircraft Corporation One-Eleven, also known as the BAC-111 or BAC 1-11, is a British short-range jet airliner used during the 1960s and 1970s. It was the second short-haul jet airliner to enter service, following the French Sud Aviation Caravelle. The aircraft was also produced under licence in Romania during the 1980s as the Rombac One-Eleven. The One-Eleven was conceived by Hunting Aircraft and developed by the British Aircraft Corporation when Hunting merged into BAC along with other British aircraft manufacturers in 1960. The One-Eleven was intended to replace the turboprop Vickers Viscount on short-range routes. The
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
