Comparison Assessment for ASCOT 2016 vs. 2019

The following is a comparison between two Aircraft Traffic Assessments, one based on 2016 data points the other based on 2019 data points. Data prior to 2016 was not available for analysis.

Findings

  • There has been no change in the Aircraft Disruption Band which is Frequent  i.e. Sound equates to a “B” road or busy “C” road i.e. regular traffic that will be noticeable at peak times which includes evenings and weekends. Location is on a secondary flight corridor or flight route. At times there will be multiple aircraft occurrences within the same hour, typically 4. There are aircraft at below 7,000 feet.
  • The number of daily disruptions* has grown from 12 to 24 due an increase in; a) out-of-hours flights, b) increase in flights below 7,000 feet, c) flights moving slower across the airspace, d) greater density/intensity of flights at certain time i.e. more flights are being grouped together in the same hour as highlighted by the 4 and 9 flight measures.
  • The location is subject to being “overflown” at various heights by aircraft not using Heathrow. See the 31 Day Assessment for a list for flights.

* See our article about the disruption index . The index does not take into consideration the mix of aircraft types. The very large aircraft such as the A380-800 tend to create an air disturbance that is noticeable from inside the house. The larger planes also tend to fly lower, have more volume and therefore have a greater visual impact.

Assessment description

Sound equates to a “B” road or busy “C” road i.e. regular traffic that will be noticeable at peak times which includes evenings and weekends. Location is on a secondary 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 4. Some of the aircraft will be below 7000 feet.
