asked the Minister of Aviation if he will raise the minimum height level for aircraft flying over the London area to 3,000 ft.

The effect of raising the minimum height of approaching aircraft in the London Central Zone from 2,000 to 3,000 ft., before they intercept the glide path, is being urgently studied and I hope to receive a report by the end of the year.

I am grateful for that reply. Will the right hon. Gentleman also look at the position regarding the glide path and try to ease the noise nuisance caused to residents living beneath it by taking steps to raise the angle of descent above the present three degrees?

That is a separate question. There are technical difficulties involved and I would be loath to go against the recommendations of the International Civil Aviation Organisation. I will look at this and all other possible measures of alleviating the burden of noise over London.
