Technical information regarding takeoff routes and acoustical pressure

GESAC, in its role as airport management company, does not hold any specific competence in matters related to routes.
In fact, takeoff and landing routes in Italy are defined by the ENAV (the National Agency for Flight Assistance) and subsequently approved and rendered mandatory by the ENAC.

 

  • Late 2004 – Installation of new technical instrumentation at the Naples Airport: safety standards were further enhanced and optimized thanks to the installation of avant-garde instrumentation: DME-Distance Measuring Equipment which permits precision instrumental takeoff procedures, ILS-Instrumental Landing System providing functional instrumentation for guided precision landings and Category A obstacle lighting systems as indicated by ICAO (International Civil Aviation Organization) specifications. With the implementation of this new radio-assistance system, the Naples airport is at the vanguard of all Italian airport structures in terms of instrumentation and infrastructure;
  • Since 14 April, 2005, pursuant to the issue of a NOTAM activating instrumental takeoffs in the direction of Naples, unidirectional use of the runway, as recommended by ICAO procedures, is now allowed thus ensuring optimal operational capabilities. In effect, landing and takeoff sequence may be conducted in one direction or the other depending upon meteorological conditions or the optimum operational conditions as defined by ENAV controllers. The one directional use of the runway also allows for better distribution of the acoustical impact on the territory in as much as the noise produced by landings will not be compounded with the noise produced by takeoffs;
  • 10 June, 2005 the Airport Noise Abatement Commission, as established by article 5 of Ministerial Decree dated 31.10.1997 (comprised of representatives from the City of Naples, the Cities of Casoria and Afragola, the Province of Naples, the Campania Region, the Ministry of the Environment, ARPAC and the airport agencies of ENAC, ENAV and GESAC) updated noise abatement procedures related to takeoffs in the direction of Naples which were made obligatory through the issuance of a specific NOTAM integrating noise abatement procedures –already in effect since 2002 - with new radio-assisted takeoff procedures (DME). In fact, noise abatement takeoff procedures take into account the need to reconcile maximum safety measures with reducing the acoustical impact on the city. This solution represents a significant reduction in the over fly area of the city and, consequently, a substantial improvement in the acoustic pressure in the urban area, particularly in the hill-top neighbourhoods, while maintaining safety standards.
  • Pursuant to the complaints made by inhabitants of certain Naples neighbourhoods, on 20 July, the ENAC officially provided for revocation of alternative takeoff procedures which allowed over-flying the city of Naples.
  • 20 July, 2005 GESAC held encounters with top ANPAC officials (the National Commercial Pilots Association) in order to make the association more aware of noise abatement procedures.
  • The route monitoring system has been fully operative since 17 July. As of that date, GESAC has obtained and analysed the weekly radar tracings, and, subsequently, has communicated any information related to observance of the noise abatement procedures on the part of the airlines to the ENAC which is the only aeronautical authority empower to sanction non-compliant airlines.
  • Since 18 August, GESAC provided that notices regarding the compulsoriness of noise abatement procedures for takeoffs from runway 24 (towards the city) are to be distributed by Airfield personnel (personnel operating directly on the aprons) to each aircraft preparing for takeoff.
