HC Deb 06 February 1992 vol 203 cc216-7W
Mr. Haselhurst

To ask the Secretary of State for Transport what progress is being made in installing a permanent noise and track keeping system at Heathrow, Gatwick and Stansted airports.

Mr. McLoughlin

I am delighted that my noble Friend has announced in another place that BAA has now committed itself to purchasing a system that should be installed by early autumn. The system will be one of the most modern in the world, and will have considerable flexibility in the ways it can be used. It will be used to enforce noise and track requirements and also to provide a lot more information about the performance of aircraft and their impact on surrounding communities.

The noise monitoring will be carried out by a total of 36 noise monitors. There will be 12 fixed noise monitors in total at the three airports, primarily to monitor noise against predetermined limits, and 24 mobile monitors that can be deployed to collect data on aircraft noise from any area near the airports. The monitors will be able to record the noise made by individual aircraft and will also be able to store data so that they can be analysed in a variety of ways. This will enable a review of noise limits to be carried out at the three airports with a view to introducing tougher limits more appropriate to modern aircraft. The noise monitoring installation should be completed by the early summer.

The track monitoring will require provision of radar data feed to the system. I understand that this should be available so as to allow installation of the track monitoring by early autumn. Again, the system will be able to identify the tracks followed by individual aircraft as well as to allow analysis of track data in different ways. This will be used to improve the accuracy with which aircraft follow noise preferential routes from the airports.

I am pleased to report that BAA is keen to involve local people through the local airport consultative committees in considering how best to use the system. It has great potential for ensuring that aircraft are operated in a way that minimises noise nuisance for surrounding communities. But the most effective use of the system will be developed only with experience: the contribution from local people and from the airlines to that development will be invaluable.
