A system of radio telephony for the control of air traffic has been instituted by the Air Minisiry, who announce that radio telephone stations are open for work at Croy: don and Lympne, for the London-Paris and Eondon-Brussels routes. The French authorities have also installed similar stations at St.
Inglevert, Valenciennes, Paris (Lo Bourget), and the Belgian authorities are arranging to instal one at Brussels (Evere). Stations will shortly be opened for the London, Birmingham, Manchester, and Glasgow route at Castle Bromwich, Didsbury, and Renfrew.
The wireless control of all the British stations, including stations licensed on private aerodromes, will be carried out by Croydon, The "wave length" is given as 909 metres, and it is stated that telephony will be used primarily for giving information as to the whereabouts of an aircraft travelling or about to travel along a route: secondly, for reporting weather conditions along the route to the machine. The foreign authorities have consented to put their stations in operation if due notification is given.
