Graphical Analysis of Trans-Canada Airlines' Progress on the North American Routes 1946–1950

Published online by Cambridge University Press:  28 July 2016


Progress of any organisation may be related either to an assumed basis within the organisation itself, or to some other organisations, preferably competitors in the same business. The second method is more realistic and by relating the corresponding data in ratios, it helps to eliminate to a great extent the influence of price changes, which distort yearly comparisons of revenues and expenses.

In the United States the trunk lines represent over 95 per cent. of the total revenue ton-miles flown on the domestic routes and in international aviation, the largest system with the highest quality of service. Therefore, by comparing in Part I the domestic services of Trans-Canada Air Lines (T.C.A.) to corresponding services of the U.S. trunk lines, the most severe criterion was chosen.

Part II contains an investigation of trends of particular expenses in relation to the total expenses for T.C.A's North American Services.
