HC Deb 15 April 1964 vol 693 cc57-8W
6. Sir Ronald Russell

asked the Minister of Aviation what international regulations exist to control aircraft landings at airports located near mountains.

Mr. Marten

General criteria for approach procedures to airports having instrument approach aids in conditions of bad visibility are agreed by the International Civil Aviation Organisation. These provide for adequate clearance from obstacles and surrounding terrain. Criteria are also agreed for weather minima for all airports used by public transport aircraft.
