Turnhouse Airport (Safety Standards) Mr. Eadie asked the Secretary of State for Trade and Industry if he is now satisfied with the standards of safety at Turnhouse Airport, Edinburgh; and if he will make a statement. Mr. Anthony Grant Turnhouse continues to maintain a good safety record but arrangements there, as at other United Kingdom airports, are kept under review. Some diversion of services is caused by crosswinds and sea-mist from time to time. The second instrument landing system, which came into operation in September, and the surveillance radar installed earlier this year are, however, now helping to improve regularity of operations.
