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
Turboprop a turboshaft. Alan Arnold Griffith had published a paper on turbine design in 1926. Subsequent work at the Royal Aircraft Establishment investigated axial turbine designs that could be used to supply power to a shaft and thence a propeller. From 1929, Frank Whittle began work on centrifugal turbine designs that would deliver pure jet thrust. The world's first turboprop was designed by the Hungarian mechanical engineer György Jendrassik. Jendrassik published a turboprop idea in 1928, and on 12 March 1929 he patented his invention. In 1938, he built a small-scale (100 Hp; 74.6 kW) experimental gas turbine. The larger Jendrassik
