Flight simulation described here is based on traditional approaches used for subsonic
passenger aircrafts. Optimization of the cruising segment has been performed taking into
account operating limitations of civil aviation. For simulating flight conditions the
embedded model of bypass turbojet engine has been used. It makes possible to calculate
power plant parameters under any flight conditions. The traditional approaches for
simulating subsonic aircraft flying in a vertical plane have also been used. Algorithm of
calculation reflects the characteristics of individual sections of the flight: take-off, initial
climb, the main climb and so on. For each section the system of differential equations of
motion specific for a given aircraft flight condition has been made up. Systems of
differential equations have been solved numerically by predictor-corrector method. A
program simulating the flight of a passenger plane has been developed. The optimal
flight program for the long-haul aircraft with high aerodynamic efficiency has been
obtained. The required en-route fuel reserve at different flight ranges has been analyzed.
