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 aircraft occurances within the same hour, typically between 4-10. Some of the aircraft 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.
