Major new departures report from CAA
The Civil Aviation Authority published a major report on 27th July into departures from Heathrow Airport. It was largely done in response to complaints from local people than aircraft have become louder and lower.
The report is packed with other useful information but note it concentrates on heights and noise. It doesn’t deal in any depth with other causes of noise such as increased concentration or a rise in flight numbers.
