Aeropostal Alas de Venezuela Colombian airline, LANSA. Until TACA de Venezuela was completely absorbed by LAV in 1958, the route to Bogotá was flown using TACA aircraft in TACA livery. During the 1950s, LAV opened a transatlantic service and began flying to Panama (in 1953). The Constellation fleet was upgraded to L-1049G Super Constellations. An order for the first jet airliner, the De Havilland Comet 1, was placed, but with the Comet crashes of the 1950s, the airline never got their Comet jets. On 24 March 1956, LAV introduced its first turboprop, a Vickers Viscount 701 which was to replace the older piston engined
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
