Sažetak
In this paper a developed mathematical model of the atmosphere with certain assumptions as well as mathematical model of the helicopter which comprise a model of its main rotor model. Main result of the simplified mathematical model of atmosphere above the wildfire, as it was expected, is decreasing of density with increasing of temperature anomaly in comparison with standard atmosphere conditions. With density decreasing driven force of the main rotor also decreases (i.e. lift force).
