Noise reduction

The launch of operations of the parallel runway RWY 06R/24L will significantly improve the quality of life for the majority of residents in Prague and its surrounding areas. According to professional studies, the construction of the new runway and the consecutive limiting of operations of the runway RWY 13/31 will ease the life of more than 200,000 inhabitants in the parts of Prague and its surroundings that are currently under this runway’s air corridors. The noise burden will become much smaller namely for the citizens of Horoměřice and city districts of Prague 5 and Prague 17 as well as for a significant part of Prague 6 (Bílá Hora, Ruzyně, Dědina). Due to the side runway’s (RWY 13/31) decreased operations, parts of Kladno and many surrounding villages, e.g. Buštěhrad, Lidice or Hřebeč, will also enjoy a noise burden relief. 

The decrease of the noise burden will not only be reached by the decreased operations of RWY 13/31, but there will also be a significant noise abatement effect following the change of its operation. Two independent runways will enable separate take-offs and landings of aircraft. While aircraft will take-off from the current main runway, the new runway will serve for landings. This division will allow more efficient management of the runway operations and more precise following of the optimal noise routes. 

The conclusion based on the given facts is that the current problems lie in the intensity of operations on the sole main runway. When two aircraft are to take-off within a short interval, the second one has to wait for the first one to fully complete its manoeuvre. This is, in reality, quite difficult to execute as while the second aircraft is waiting for its take-off, there is sometimes a third aircraft on its final approach which is then blocked by the second waiting aircraft on the only operational runway. In such case, there is only one solution: The first aircraft is instructed to deviate from the optimal assigned route to make room for the second aircraft to take-off which enables the third one to land. As a result, aircraft fly over areas where they were not present in the past. If there is an independent runway assigned for take-offs it will not be a problem to let the second aircraft wait since it will not block any aircraft on its final approach as the new parallel runway will be designated for its landing. Similar procedure will be applied to arrivals. This will result in aircraft flying in low altitudes solely above the assigned areas.
