HC Deb 21 January 1959 vol 598 c25W
47. Mr. P. Williams

asked the Minister of Transport and Civil Aviation what instructions he is giving to the British delegates to the forthcoming International Civil Aviation Organisation Conference in Montreal with special reference to the adoption of British navigational aids.

Mr. Hay

The United Kingdom delegation will be instructed to advocate strongly the adoption of the Decca Navigator System as the only available short-range navigational aid which effectively meets the requirement of safe and efficient use of air space in areas of high traffic density.
