Abstract:

Seasonal and annual great circle route temperatures in degrees Celsius are computed for 50-, 75-, and 85-per cent reliabilities of occurrence, i.e. temperatures which are not expected to be exceeded 50, 75 and 85 per cent of the time respectively. The temperatures and their standard deviations are computed over some 2000 selected air routes at the 10,000-, 20,000-, 30,000-, 40,000- and 53,000-foot levels and in addition AT THE 5000-, 10,000- AND 15,000- FOOT LEVELS FOR ROUTES 400 nautical miles in length. The great circle distance between terminii is also tabulated. A 7090 was used to compute the route temperatures. Input data for the program consist, for each level, of a grid composed of the mean temperature and its standard deviation at the intersection of each 5 degrees of latitude with each 10 degrees of longitude between 60 degrees S and 60 degrees N and at the intersection of each 5 degrees of latitude with each 20 degrees of longitude south and north of 60 degrees S and 60 degrees N respectively. Supplementary airport surface temperatures are tabulated by month, quarter, half year and year for the 0, 50, 75, 85, 95 and 100 per cent probability of not being exceeded. Lackeys method, adapted for the 7090, was used to compute the surface temperatures.
