A comparison of airplane productivity and utilization levels derived from commercial airline type schedules based on 1995 passenger demand forecasts was made between two subsonic and four supersonic cruise speed aircraft. The cruise speed component is the only difference between the schedules. Productivity-to-speed relationships were determined for three discrete route systems; North Atlantic, transpacific, and North-South America. All three route systems show airplane productivity practically doubling between cruise speeds of Mach 0.82 and 2.0. Above Mach 2.0, further productivity gains are function of the particular route system. The route systems with longer cruise distances are able to take advantage of cruise speeds higher than Mach 2.0. A weighted average of all three route systems shows only an additional 10 percent increase in productivity of the Mach 2.7 aircraft over the Mach 1.0 aircarft. (DePo)
