Airport and noise
The minimization of the aircraft-generated noise affecting the territory and resident communities is a paramount priority for Naples Airport in view of its balanced and sustainable management.
For this reason, it is important to measure the noise produced by aircrafts in order to objectively monitor the evolution of this phenomenon over time and to assess the efficacy of the adopted measures.
To measure aircraft-generated noise, the regulation prescribes the adoption of ad hoc method and metrics.
Indeed, the level of noise is measured during the whole day and not just during the single noise event, thus allowing quantifying the amount of energy associated to acoustic events unfolding over a long period. As for night events, the value becomes ten times greater
In these web pages you will find the most updated information regarding aircraft-generated noise and the answers to the most frequent questions.
Today’s aircrafts are more silent than in past and Airlines are gradually replacing fleets with aircraft with lower noise and environmental impact.
The noise produced by aviation operations is mainly due to two factors: engines (during take-off) are the first and the second is the impact of air on the fuselage, on the wings and on the landing gear (during landing).
Moreover, the take-off takes place on a smaller part of land, because aircrafts rise very quickly, while landings involve wider areas.
For this reason, one of the main factors of aircraft-generated noise management is to carefully distribute operations on both runway directions.
Unidirectional use of the runway: indeed, Naples Airport has a runway oriented east/west, which can be used unidirectionally in both directions. This means that landings and take-offs can take place unidirectionally in one or the other side of the runway depending on the weather and on the optimal operating conditions defined by air traffic controllers. The balanced use of the runway provides that takeoffs take place mainly in the direction of the City of Naples and landings in the direction of the City of Casoria.
Noise abatement procedure for take-offs in the direction of the city of Naples: From 2005, the Airport Commission for noise management (Commission set as per art. 5 of the Ministerial Decree dated 31/10/97) developed a specific noise abatement procedure for take-offs in the direction of the City of Naples, in order to minimize the impact during the noisiest operations. This procedure reconciles the maximum safety given by the most updated radio-assistance equipment with the abatement of noise impact on the city.
Indeed, it allows a considerable reduction of the overflying territory and thus a substantial improvement of acoustic pressure on the city, while maintaining safety standards unchanged.
In 2006, Naples International Airport was among the first airports in Italy to equip itself with an aviation noise monitoring system, thanks to which we can constantly monitor the levels of the noise generated by aviation operations.
The monitoring system was realized and is managed according to the current Italian regulation; it consists of eight phonometric detectors, among which seven are fixed and one is mobile.
Thanks to the acoustic, meteorological and operational data contained, the monitoring system allows to:
- to monitor every single flight operation in our airport, thus to assess the compliance with the noise abatement procedure for take-offs in the direction of the city of Naples.
- to measure the acoustic impact on the territory through the phonometric detectors, by registering the data needed to calculate the noise pollution indexes (LVA, Airport Noise Level Assessment, as defined by the Ministerial Decree dated 31 October 1997).
- to analyse, record and manage noise complaints,
