Aircraft noise is, understandably, a significant issue for some of our neighbouring communities. Achieving the most appropriate balance between the needs of a growing airport that serves as a major transport hub for millions of business and leisure travellers, and the rights and requirements of our nearest residential neighbours provides an ongoing challenge for Dublin Airport as it does for all airports of its size.
The International Civil Aviation Organisation (ICAO) has endorsed the EU Directive 2002/30/EC concept of a ''balanced approach'' to aircraft noise management. This approach incorporates four key elements to the mitigation of noise levels at airports.
• The reduction of noise at source (quieter aircraft)
• Use of land planning and management
• Noise abatement operational procedures
• Operating restrictions
Aircraft noise is measured in decibels or dB for short. Modern subsonic jets are about 30 dB quieter than their first generation, similar sized counterparts. As a sound reduction of 10 dB is roughly equal to a halving of noise volume perceived this technological development represents about a 90% reduction in perceived noise. All aircraft operating at Dublin Airport conform to the current ICAO standards and as older aircraft are phased out in the short term, this situation will continue to improve.
All aircraft arriving and departing Dublin Airport come under the direction of the Irish Aviation Authority who provides air traffic control services in Ireland and they are responsible for the controlling and routing of aircraft. Nonetheless, the daa have regular meetings with the Irish Aviation Authority to continuously review the track keeping of aircraft in the vicinity of the Airport. This function is carried out by the Noise & Flight Track Monitoring Service of daa.
The primary objective of the Noise & Flight Track Monitoring Service (NFTMS) is to provide an information and complaints handling service to the local communities to deal with all aspects of aircraft noise and track keeping. In recognition of its own responsibilities in this area, Dublin Airport introduced a noise & flight track monitoring system to ensure minimum disruption to the local community and to challenge deviations when they occur through an investigation process with the IAA and the airlines in question. The NFTMS gathers all information on aircraft approach and departure routes and the resultant noise levels at a number of key locations. In this context Dublin Airport has invested €1 million in the installation of a Noise and Flight Track Monitoring System, purchased from Bruel & Kjaer in Copenhagen, Denmark. Besides its aircraft tracking facility, the system is comprised of a number of fixed NMTs (Noise Monitoring Terminals) that monitor arriving and departing aircraft. The NMTs are located at:
• Balcultry monitoring Runway 34 Departures & Runway 16 Arrivals
• Artane monitoring Runway 16 Departures & Runway 34 Arrivals
• Bay Lane monitoring Runway 28 Departures & Runway 10 Arrivals
• St. Doolaghs Monitoring Runway 10 Departures & Runway 28 Arrivals
• Coast Road monitoring Runway 10 Departures & Runway 28 Arrivals
• Feltrim monitoring the local area
• Bishopswood monitoring the local area
The reduction of aircraft noise on neighbouring communities is the joint responsibility of the airport authority, Irish Aviation Authority and the airlines that operate at Dublin Airport. If you need further information on noise or flight track issues please phone free-phone 1800200034.
