HC Deb 18 April 1951 vol 486 cc170-1W
86. Mr. J. Grimston

asked the Parliamentary Secretary to the Ministry of Civil Aviation why Airway Blue Two crosses the Isle of Arran at a height which is less than the safety height.

Mr. Beswick

The lowest cruising altitude for this sector of Blue Two is specified in paragraph 6 of Appendix A to Notice to Airmen No. 93/51 and is 4,000 feet. This is greater than the safety height over the Isle of Arran.
