Question: To ask the Secretary of State for Transport, what areas and how many people will be exposed to different amounts of aircraft noise (a) at night in (i) 2015 and (ii) 2030 and (b) in 2030 based on an average six hour day in connection with the proposals relating to Alconbury airfield contained in the Department's Consultation, The Future Development of Air Transport in the United Kingdom: South East.

Answer: Mr. Djanogly: To ask the Secretary of State for Transport what areas and how many people will be exposed to different amounts of aircraft noise (a) at night in (i) 2015 and (ii) 2030 and (b) in 2030 based on an average six hour day in connection with the proposals relating to Alconbury airfield contained in the Department's Consultation, The Future Development of Air Transport in the United Kingdom (South East). [74822] Mr. Jamieson: The South East and East of England Regional Air Services study (SERAS) analysis included illustrative examples of night-time noise footprints for all airport options. The approach adopted is set out in paragraph 6.9.4 of the SERAS stage two appraisal findings report and the results of this work, relevant to the Alconbury option, are presented in paragraphs 12.8.3 and 12.8.4. These indicate that, using the 90dBA SEL (sound exposure level) footprint for the noisiest aircraft envisaged operating at night, between 300 and 10,600 people might be contained within the footprint--subject to airport operation. The numbers of people affected with this option by different amounts of aircraft noise (daytime) was not assessed at 2030. Copies of the above report are available in the House libraries.
