Heathrow’s proposed flight paths – Colnbrook’s future!

Heathrow’s consultation on airspace changes

The Colnbrook meeting is on Wednesday 20th February between 2 and 8 pm in the Village Hall.

Other events will take place at various locations between 8th January and 4th March 2019 as set out below.

What will these changes mean for Colnbrook?

In short they will mean more noise and air pollution, with many parts of Colnbrook and Brands Hill being seriously affected by as many as 47 flights per HOUR, and all of those will have a noise level at the BP station of at least 65 decibels – which exceeds the WTO limit of 45 decibels.

How will the new flight paths affect me after expansion?

This series of maps demonstrate the effects that the changes after expansion will have on our communities.

****All of these maps are based on the position of the blue marker****

 

1. ARRIVALS

ALL Flights will be below 1,000 feet

There will be an average of 47 flights per hour

The noise level for all flights will be in excess of 65 decibels

2. DEPARTURES – WESTERLY

ALL flights will be below 1,000 feet

There will be an average of 17 flights per hour

Three of these flights will be in excess of 65 decibels

3. DEPARTURES – EASTERLY HEADING NORTH

Flights will be below 5,000 feet

There will be an average of 17 flights per hour

Three of these flights will be in excess of 65 decibels

3. DEPARTURES – EASTERLY HEADING SOUTH

Flights will be below 5,000 feet

There will be an average of 17 flights per hour

Three of these flights will be in excess of 65 decibels

4. ARRIVALS - Independent Parallel Approach (2 runways)

This is where matters become rather more complicated. This is the affected area and any flight over Colnbrook (not detailed on the map, would be under 1,000 feet.

For the sake of simplicity, here is the Heathrow description of the flights etc of this map

5. MATTERS TO NOTE

A. DECIBELS

On a ruler, a distance of 20cm is twice as long as a distance of 10cm and 30cm is three times as long. But the logarithmic decibel scale goes up in powers of ten: every increase of  10 dB on the scale is equivalent to a 10-fold increase in sound intensity (which broadly corresponds with a doubling in loudness)

B. NIGHTTIME AND SLEEP REQUIREMENTS

Heathrow are planning (if 3rd runway goes ahead) to give residents up to 6.5 hours respite at an as yet undefined time between the hours of 11 pm and 7.00 am. The World Health Organisation recommend a good nights sleep is 8 hours for adults. However they will still seek up to 18 flights during these hours.

Colnbrook Community Association comment

We continue to oppose Heathrow expansion due to the existing illegal (under WHO regulations) air quality and noise pollution. Slough BC has done next to nothing over the past ten years to bring these down to legal levels and are thereby continuing to harm the health of residents, not only in Colnbrook but also with the proposed expansion, to previously unaffected residents across the Slough  Borough and our neighbouring village communities.
