HC Deb 07 June 1976 vol 912 c562W
Mr. Andrew F. Bennett

asked the Secretary of State for Trade, how soon methods such as "managed drag" and "continuous descent" will be applied to airports other than Heathrow.

Mr. Clinton Davis

As my hon. Friend is aware, many airlines already practice some form of managed drag at Heathrow and other United Kingdom airports. The Civil Aviation Authority is discussing with airlines and other interested parties plans for full-scale operational trials of continuous descent at Heathrow Airport and of modifications to existing Air Traffic Control procedures which will facilitate the extended use of managed drag. The wider application of similar procedures will be considered when the results of these trials are known.
