Aircraft on the last seven miles of their approach to Heathrow are subjected to random checks by precision approach radar. During the last three months less than 0·4 per cent. of the aircraft checked came below the 3 degree glide path.
When more than seven miles from Heathrow pilots are instructed to maintain a height of not less than 2,000 ft. The checks mentioned do not extend as far as Hendon but I am considering instituting wider checks in the near future.
Yes, indeed. I will bear this point in mind. I have instituted special discussions during the summer for I, and I think many other Members, have been worried about the degree of noise over central London, and I hope to make sure that the regulations are observed.
I am giving very close attention to this matter. With the expertise of a layman, I have occasionally thought that planes were flying lower than they should have been at the entrance to the glide path. I have had this checked It occurs occasionally but only very infrequently.
