§ 34. Mr. Marten
asked the President of the Board of Trade if he will make a statement about the application of grooved runways to British ariports.
§ Mr. J. P. W. Mallalieu
Grooved runways are a feature of Manchester and Leeds-Bradford airports. Grooving is one of several methods of reducing the risk of aircraft skidding or aquaplaning on wet runways.
§ Mr. Marten
Could the Minister say when they will be grooved at the British Airports Authority airports?
§ Mr. Mallalieu
That method is only one of several for providing extra safety. It is the most expensive. What method is employed must depend on local conditions.
