HC Deb 07 December 1949 vol 470 cc1847-9
3. Air-Commodore Harvey

asked the Parliamentary Secretary to the Ministry of Civil Aviation what regulations he has made prescribing minimum conditions of

maximum period of one to two years? How does the Parliamentary Secretary expect any business to be run in a businesslike way when this time is insufficient to allow depreciation on the equipment? Will he bear this point in mind, if he is to continue with this system, and see that the operators get a proper deal?

Mr. Lindgren

The conditions under which the agreements are made are well-known to those asking for them. It is true that the agreements to which I have just referred are, in the main, for one year, but some of them are for two years.

Following are the details:

visibility and cloud base under which aircraft are permitted to use the Ground Controlled Approach system; and what are these minimum conditions at each United Kingdom airfield equipped with the system.

Mr. Lindgren

No such regulations are in force.

Air-Commodore Harvey

Could the hon. Gentleman say what are the minimum visibility conditions which are prescribed at Prestwick in connection with the use of the Ground Controlled Approach system, and whether such conditions were in force at the time of the K.L.M. accident on 20th October, 1948?

Mr. Lindgren

There are no regulations as to visibility in operation anywhere; it is for the operator to lay down the conditions in which operations shall take place. The only things we have promulgated are break-off heights, etc., for aircraft in the event of an approach by G.C.A.
