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 Kaman's K-125 synchropter, which used a Boeing T50 turboshaft engine to power it on 11 December 1951. Compared to turbofans, turboprops are most efficient at flight speeds below 725 km/h (450 mph; 390 knots) because the jet velocity of the propeller (and exhaust) is relatively low. Modern turboprop airliners operate at nearly the same speed as small regional jet airliners but burn two-thirds of the fuel per passenger. However, compared to a turbojet (which can fly at high altitude for enhanced speed and fuel efficiency) a propeller aircraft has a lower ceiling. The most common application of turboprop engines in
