HC Deb 16 December 1964 vol 704 c93W
Mr. Galbraith

asked the Minister of Aviation whether Abbotsinch will be fitted with equipment to enable blind landings to take place.

Mr. Stonehouse

The airborne and ground equipment needed for blind landing by commercial airlines is still under development. It is not yet possible to say at what aerodromes the installation of the fully developed equipment will ultimately be justified but when Abbots-inch is opened it will have the latest type of instrument landing system installed at both ends of the main runway. This system permits suitably equipped aircraft to land under 100 ft. cloud base in quarter-mile visibility.
