Assessment ScoreCard – 31 Day

Aircraft Traffic Assessment: 31 Day Scorecard



The symbol indicates the measure is better than the average when compared with other assessed
UK postcodes. The ❌ represents the opposite. Assessed averages are shown in brackets.

See: for a full explanation about the Assessment scorecard.

Assessment Scorecard headlines

All Assessments are based on an ambient background noise of 40 decibels i.e. a quiet residential area. If your property is located near to a busy road i.e. 70-75 decibels, the noise impact from aircraft will be significantly reduced, whilst the road remains busy.

Note: Airborne aircraft noise is typically in the range of 45dB - 65dB for heights below 26,000 feet and for a duration of 30-50 seconds. Whereas the average car, bus or HGV the duration is only a few seconds.

Assessment description

Sound equates to an "A" road or a busy "B" road i.e. regular traffic that will be noticeable at peak times which includes evenings and weekends. Location is on a primary flight corridor or flight route or in a flight holding stack area. At times there will be multiple flight occurrences within the same hour, typically between 4-10. Some of the flights will be below 7000 feet.

Our scorecard is designed to provide a greater understanding how the assessment was reached for your selected UK post code. To enable you to validate our assessment we also provide up to 10 occurrences when we believe the disruption will be at its highest.

For those that would like to perform their own analysis we can also provide the low level flight data that includes the length of time a plane existed inside your select airspace bubble.
