The article considers the influence of climatic conditions on subsonic long-haul passen-
ger aircraft optimal flight program at descent segment. Flight program optimization at
this segment takes into account civil aviation operational constraints, namely the vertical
velocity component limitation at descending. The flight segment descending-braking op-
timization is performed while minimizing the fuel consumption at this flight segment. In
the flight simulation an integrated model of turbojet engine is used, which allows us to
calculate the power plant characteristics at each step of integration of differential equa-
tions. Flight simulation and power plant characteristics are based on modern traditional
approaches. The study considers the climatic conditions influence on the aircraft de-
scending optimal program, carries out calculations for 6 standards of air temperature
changes in height (depending on climate zone). The article examines the atmospheric
conditions influence on the flight program optimization results at the descending seg-
ment.
Keywords: passenger aircraft control, aircraft control optimization, optimal flight pro-
gram, flight simulation, long-haul passenger aircraft, atmospheric parameters influence,
vertical velocity components, operating limitations.
