Sažetak
The helicopter generated noise at and around the airports is lower than the noise generated by aeroplanes, since their number of operations, i.e. the number of take-offs and landings is much lower than the aeroplanes. Out of some hundred operations a day, helicopters participate with approximately 15%, but the very impact of noise is by no means negligible, since the number of helicopter flights above urban area is constantly increasing. This paper attempts to analyze this phenomenon and the type of helicopter generated noise, its negative impacts, to explain the flight procedures and the operative procedures during take-off, landing and overflight of helicopters in operations in the vicinity and outside airports, as well as the methods of measuring and determining the limit of noise level and the resulting problems.
