* JANUARY 2OTH, 1949 FLIGHT CIVIL AVIATION NEWS INITIAL DEVELOPMENT ; New figures for the production Ambassador show that with an all-up weight of 52,800 ib, operating from a runway length of 1,480 yards, 11,520 Ib could be carried for 500 statute miles cruising at 42 per cent METO power. International Aeradio in Burma : Airline Agreement Between Pakistan and Ceylon : Bahamas Airways Taken Over by B.S.A.A. SURVEY EXPEDITION TO INDIAA IR SURVEY CO., LTD., a subsidiary of the FaireyAviation Co., Ltd., has recently despatched an expedition to undertake Government surveys in India, Nepal and.Pakistan. The expedition left White Waltham in a Dakota which, equipped with high-altitude engines, will be used formany of the photographic flights over mountainous country •where photographs will be taken from 20,000 to 25,000 feet.Mapping experts accompanying the expedition will remain in India for some years to train the personnel of another sub-sidiary company of Fairey's, Air Survey Co. of India, Ltd., __• which is being re-equipped with the most modern camerasand mapping process apparatus. This company, previously known as Indian Air Survey and Transport, Ltd., operatesfrom Dum Dum, Calcutta. _,,.. - AIR CHARTER A LTHOUGH the general tone of the air freight market con- •** tinued rather quiet at the opening of the year, carriers are said to be busier than for the same period in 1947. At present there are enough freighter aircraft to meet the char- terers' demands even though the larger part of the Halifax fleet is still on the Berlin airlift. Dakotas have been em- ployed on several passenger charters, including the repatriation of the crew of an Egyptian ship from Liverpool to Alexandria. Such charters show a saving in expense to the ship owners since whilst being repatriated ships' crews are entitled to full wages, and sea transport, in spite of the lower fares, can be expensive for the ship owner. In this particular case the total cost of air transport plus wages in flight was slightly lower than the cost of sea transport plus wages on board. NAVIGATION AIDS IN BURMA LEADING British manufacturers of communication equip-ment, including E. K. Cole, Ltd., General Electric Com- pany, Pye Ltd., Rediffusion Ltd., Arthur Lyon and Co. and E. J. Philpott, have undertaken to equip twelve air strips in bush districts of the interior in Burma with radio naviga- tional aids before the monsoon breaks at the end of March. Failure to complete the contract which is understood to be worth ^43,000 will jeopardize the safety of flying operations by the recently formed Burma Airways. The Government of B 17 Burma made International Aeradio Ltd. responsible for designing the overall layout of the equipment and for hand- ling sub-contracting. At the end of February the equipment will be flown by International Aeradio from Bovingdon to their own station at Rangoon. From there the equipment will be carried and installed by that company. I.C.A.O. COMMUNICATIONS CONFERENCE THE growth of air traffic throughout the world has produceda serious scarcity of radio frequencies for communications between aircraft in flight and ground stations. At the thirdsession of the International Civil Aviation Organization Com- munications Division, which opened in Montreal on Januarynth, representatives of the 25 member nations are examining a draft allotment for the air routes. The draft plan wasoriginally prepared at a Conference of the International Tele- communications Union, the agent for the United Nationsresponsible for allocation of all radio channels, and first steps in the allocation programme were taken at New Delhi lastNovember when an I.C.A.O. Regional Meeting co-ordinated the frequency requirements for South East Asia. At Mon-treal, European frequencies are being discussed concurrently with the Divisional Meeting and another I.C.A.O. RegionalMeeting will study and co-ordinate the frequency requirements for the Middle East and African-Indian Oceans next March.The Air Navigation Commission and the Council of I.C.A.O. will consider the results of these meetings before they are trans-mitted to the I.T.U. by the end of June this year. At present only 149 radio channels in the high frequency bands are avail-able for the exclusive use of civil aviation throughout the world, and whereas during day-light hours several transmittingstations can operate on the same frequency without inter- ference provided they are sufficiently far apart, at night thosestations are likely to interfer seriously with each other owing to the greater range of radio signals. The CommunicationsDivision is also taking into account the experience gained throughout the past ten months in the application of I.C.A.O.Communications Procedures which came into effect in April last year. It is understood that standardization of the formand content of messages and the introduction of common prac- tices and methods in handling messages has enabled presentcommunication circuits to handle increased traffic, but even so the Division is now considering additions and amendments.
