§ 63. Mr. MANDERasked the Under-Secretary of State for Air what steps are being taken to ensure that air ports in this country, and in particular Croydon, are being equipped with facilities to enable aircraft to land under conditions of low visibilty; and whether the Lorenz system installed at Heston has been tested to determine whether it meets with the Air Ministry requirements?
§ Sir P. SASSOONIt is the general policy of the Air Ministry to encourage the use of blind landing wireless equipment, in the interests of safety in fog and other conditions of low visibility, but my Noble Friend has no powers to require aerodrome owners to install such equipment. So far as Croydon is concerned, the matter is receiving close attention and investigations are actively proceeding into the merits of different systems. As regards the last part of the question, the Lorenz system at Heston has been successful in use to date, but all the technical tests to which it is being subjected have not yet been completed.
