Identifying Economically Optimal Flight Techniques of Transport Aircraft

A treatment of identifying optimal flight techniques for transport aircraft with respect to direct operating cost and profit or return on investment is derived for given sector mission criteria and assumed reference time frame utilization. A series of models used to simulate maintenance and materiel costs accurately and block fuel expenditure and revenue have been introduced to force the direct operating cost and profit or return on investment expressions as continuous functions, allowing for determination of their respective minima and maxima.
