Aircraft Overflying Assessments & Surveys

Is your home or garden impacted by Aircraft? By clicking on our 31 Day Interactive aircraft overflying visualisation we will let you know – all that’s required is a UK postcode.

We’ve already analysed over 900 UK postcodes, many of which are available free online. However, should you want your own specific postcode area analysed there is a nominal fee of either £5.00 for the past 31 days or £10.00 if you require the analysis to use the 2019 flight datasets i.e. pre-pandemic .

You will be provided with sufficient information for you to determine whether your sleep patterns and life style is likely to be impacted by overflying aircraft. Additionally our 31 day Assessment helps explain from which airport the aircraft originate from.

£15 secures both the “2019 – pre-pandemic analysis” and also the “Last 31 Day” aircraft overflying Impact Assessments. Included are our personalised comments about the likelihood of; a) sleep disturbance, b) weekend noise disruptions, c) exposure to aircraft pollutants, and d) our interactive visualisation .

Both Assessments provide facts regarding aircraft overflying for any 5+ digit UK postcode. This includes; occurrences of overflying, flight heights, flight times by day & every hour period, occurrences of Arrivals vs. Departures, density and intensity of flight traffic, and suggested busiest times to visit the postcode in person.

In the UK it’s highly likely every property is being actively Overflown by aircraft 7 days a week for 20 hours a day and that city postcodes are overflown by 4,500+ planes per day! Don’t believe it, then request an Aircraft Assessment for your postcode, you’ll be very surprised by the results.

We provide independent research and analysis of aircraft movements, i.e. factual evidence, to help you determine whether the scale of noise and silent emissions could impact you and your families well-being.

So what do we mean by being Overflown?

Being overflown means an aircraft flying within 1 mile radius of your home or postcode, either inbound or outbound, from ANY airport. Our research shows that people living 30-50 miles from an airport are often more overflown that those living 3-6 miles from an airport. Why? The real life image below illustrates why. This was a single inbound Gatwick flight that overflew multiple postcode between 5:00am and 6:00am. Now extrapolate this scenario by the 1000s of flights that criss-cross the UK everyday and you will understand how flights can impact you.

The following is another example of a single flight Overflying multiple postcodes ranging at a height from 4,000 feet to 15,000 feet with sometimes less and 90 seconds separation between flights. This example was an arrival into Heathrow, notice the use of both the arrival stack and also the “trombone” shaped holding route over the North London postcodes. At the same time the postcodes were also being overflown by aircraft from other airports too.

On average it takes around 30-50 seconds for aircraft noise to disperse and that 50% of the flights occur at weekends, late evenings and early mornings. You’re better off knowing so have an Assessment today!

Why is our Aircraft Assessment required? The aviation industry, the local authorities and the associated government bodies are not legally required to report and share aircraft movements by postcode, so they don’t. Meaning we buy and rent our homes and also visit our open spaces without any understanding of potential noise and emissions created by the aircraft being routed overhead. Buying and renting are expensive in terms of emotional and financial costs so try and avoid getting trapped into a situation you had not expected.

Is it all about the decibels? We think not as the aircraft cruising noise, excluding maneuvers, tends to be around 45-55 dBs, which is about the same as a car. However, the noise duration is typically 30-50 seconds i.e. it’s not a single short term event, and this is what can causes an annoyance. Additionally, the noise created at 1,000 feet and above is not readily absorbed by trees and buildings and can merge with noise coming from other nearby aircraft. This in turn creates a continuous low level background rumble.

What emissions? Whenever you hear aircraft noise there are very likely to be emissions too. By having an understanding of aircraft movement and how long it takes for an aircraft to cross the postcode’s airspace it is then possible to calculate the scale of the emissions. Emissions such as; Carbon Dioxide, Carbon Monoxide, Nitrogen Oxide and Particulate Matter such as soot. It’s estimated that an aircraft emits 250kg of Carbon Dioxide per hour. Meaning, 2 planes navigating the same postcode at the same time for 20 seconds will emit; 2.78kg of Carbon Dioxide, 14.30 milligrams of Nitrogen Oxide and 1.84 milligrams of Particulate Matter.

Our focus is on identifying the potential causes of continuous noise disturbances and emissions at the times when we are at our most sensitive e.g. early morning, late at night and at weekends.

  • Assessment details are available for only sponsored postcodes. Pins can be filtered, the colour represents the Disruption Assessment result: Green (none; minimal), Yellow (occasional), Amber (regular, frequent), Red (high, very high, extremely high)

You may also search our free assessment directory by; UK postcode, town, county. New Assessments are sponsored and updated daily.

The Assessment processes billions of “research quality” data points and is a fusion of multi-million £s of IT investment overlaid by real life experiences. We can also supply the detailed evidence for each Assessment.

The Assessment is designed to highlight locations for; buyers, sellers, renters, holidaymakers, and property investors where there is a high likelihood of experiencing aircraft noise and emissions.

We also include articles that describe some of the causes and patterns that can result in aircraft pass-bys such as; flight paths, flight corridors, flight routes and flight holding stacks. You can also contribute to the research project by sponsoring a £15 Assessment for your postcode.

Who uses our service?

  • Home buyers wanting to know about possible Aircraft pass-by at a specific location e.g. by postcode, street, or plot.
  • Home sellers wanting to demonstrate to potential buyers their plot is not subject to excessive aircraft pass-by.
