Routine Flight the TCA purchase of the British-built Vickers Viscount turboprop-powered airliner, the Winnipeg base is also in the midst of introducing jet engine technology for its engineering staff and technicians. TCA is the first North American carrier to use turboprop aircraft and air crews are also working up procedures to introduce the new airliner. The first Viscount is carrying out orientation flights for ground and air crews and the "On the Spot" crew are invited to come aboard on a test flight. The "On The Spot" series debuted in 1953, with the 39 episodes, initially 15 minutes in length. For the
Jet airliner turbofans, which are quieter and more fuel-efficient. The first airliners with turbojet propulsion were experimental conversions of the Avro Lancastrian piston-engined airliner, which were flown with several types of early jet engine, including the de Havilland Ghost and the Rolls-Royce Nene. They retained the two inboard piston engines, the jets being housed in the outboard nacelles. The first airliner with jet power only was the Nene-powered Vickers VC.1 Viking "G-AJPH", which first flew on 6 April 1948. The early jet airliners had much lower interior levels of noise and vibration than contemporary piston-engined aircraft, so much so that in 1947,
