HC Deb 21 April 1986 vol 96 c46W
18. Mr. Ottaway

asked the Secretary of State for Transport if he is considering any further initiatives to ensure that aircraft comply with noise preferential routes; and if he will make a statement.

Mr. Michael Spicer

Yes, I am examining what more we could do to ensure compliance with noise preferential routes at Heathrow, Gatwick and Stansted. One possibility I am considering is the permanent monitoring of the track-keeping performance of aircraft.
