Very high air traffic density in the largest airports and in their vicinity involves that the air traffic in the largest
airports and their areas of operations approaches the capacity limits. Such high density of the air traffic adversely
influences the natural environment in the vicinity of the airports due to the increasing cumulative noise level and the
concentration of environmentally hazardous substances. One of the possibilities to improve the situation is to work out
innovative solutions aimed at decreasing the aircraft pollution and improving the transport effectiveness. One of the
major concepts is using magnetic levitation (MAGLEV) technology to support aircraft take-off and landing. If the
aircraft could take-off and start the initial climb phase with the ground power, the installed power may be reduced,
resulting in less weight, less drag and less overall fuel consumption which leads to emission reduction. These
advantages, the lower fuel consumption and emissions, increase sustainability of the transportation system. Different
conditions of the take-off give possibilities to shape the trajectory after the take-off in order to decrease the negative
influence on the environment. The aim of the present work was to determine the optimal conditions of the take-off and
the optimal climb trajectory of the aircraft aided in the ground phase of the take-off by the system using the MAGLEV
technology, minimizing the fuel consumption. The simplified algorithm of optimization of the flight trajectory was used
in this work; it uses the method of approximation of the flight path by the third degree polynomial.
