HEATHROW TRIALSAn 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).

Trial 1:

westwards into our area, affecting a zone between Ascot centre and Sunningdale centre.

• 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.
