This document provides an overview of recent trials at Heathrow Airport aimed at consolidating aircraft departures into narrower corridors. The purpose is to alleviate pressure on air traffic controllers and reduce aircraft separation. Trial 1 impacts a broad area including Sunningdale and Sunninghill by shifting the Midhurst westerly departure corridor into these regions, concentrating departures. Trial 2 further complicates matters by altering the Southampton Departure Route, significantly affecting areas between Ascot and Sunninghill. The trials lead to intense noise disruption and impact on local communities.

Heathrow trials An Overview.
Trial Purpose: To concentrate all departures into a few narrow corridors to: • Reduce the pressures on air traffic controllers, and • Reduce aircraft separation.
Impact on our area: Trial 1 • Moves existing Midhurst westerly departure corridor westwards into our area. • Forces all departures into our area, rather than being spread out over a wide area. • Corridors spread is from just east of Sunningdale to just west of Heatherwood. • Impacts most severe in Sunninghill, as affected by all 4 routes (2 from each runway).
Impact on our Area: Trial 2 • Area affected by changes to both the Southampton Departure Route and the Midhurst Departure Route. • Existing Midhurst westerly departure corridor moved westwards into our area, affecting a zone between Ascot centre and Sunningdalecentre. • Existing Southampton DC moves significantly south and affects a corridor from W of Ascot to east of Sunninghill. • Forces all departures into our area, rather than being spread out over a wide area. • Impact is very severe.
