FLIGHT OCTOBER 2ND, Civil Aviation News • . . . . in world airline services will be forwarded to the internationalorganizations of airlines and to government aeronautical agencies. The Conference was divided into four workinggroups: Communications and Radio Aids (COM); Operations (OPS), Engineering and Maintenance (ENG); and Aids andFacilities (AIDS). Over a hundred outstanding technicians of twenty airline companies participated in extensive discussionof every phase of air transport engineering, including ground facilities, navigation and landing aids, communications, andoperation and maintenance practices. The chairman of the Conference was Mr. C. C. Eteensma, ofK.L.M., who stated at the close of the meeting: " In ten days we have managed to make substantial further progress towardthe world-wide uniformity and simplification of air transport practices which is the prime necessity for safe and efficientoperation of the world air transport system." Mr. C. H. Jackson, of B.O.A.C., chairman oi the Engineeringand Maintenance working group, said that his group reviewed a nuinbei of items of importance in relation to airworthinessand maintenance. Many recommendations were made to I.C.A.O. or to the member airlines, amongst which the fol-lowing were of outstanding importance:-— (1) Procedure for the introduction of agreed corrections of local temperatures on aircraft performance, particularly at take-off. (2) Improvements to the existing I.C.A.O. airworthiness regulations for the climbing performance of multi-engined aircraft with one Engine inoperative, (3) The limitation on the operating weights of aircraft which do not yet have to meet the I.C.A.O. requirement. (4) The airworthiness requirements for cargo aircraft. (5) The interchange of information on overhaill and main-tenance experience between airlines using similar air- craft with a view to attainment of maximum safety andeconomy. (6) The introduction of standards for servicing connections onaircraft; colour or other recognition codes for supplies and aircraft auxiliary systems; the international stan-dardization of certain defined and rapidly consumable spares. Effective measures in this direction should lead tothe pooling of ground equipment, etc., between operators and consequent increases in safety and economy. THE MECHANIZATION OF METEOROLOGY T^ELEGATES to the International Meteorological Conference-L'at Toronto recently viewed demonstrations of electrically operated machines which record and tabulate meteorologicaldata by means of "punch-cards." Such details as tempera- ture, pressure, cloud cover, rainfall, windspeeds and directionare punched up on cards which are put through sorters, tabu- lators, collators, multipliers and verifiers to achieve the desiredcomputation. Up to 480 cards per minute can be processed by these machines, which simultaneously tabulate and print theresults. Mechanical punch-carding results in considerable saving intime and cost. In addition, these machines have a practical THE WATCH COMMITTEE : At the first meeting of the Air Transport Advisory Council held in London on September 23rd (left to right) : Mr. John Ure Primrose, Sir Donald Banks, Lord Terrington (chairman), Mr. G. S. Szlumper and the Hon. W. L Runciman. application, enabling speedy decisions to be taken re^ardinjdistribution of produce and, as was done during the war" deter' mining local conditions in particular areas. Over the past sixty years the International Weather Bureauhas collected one billion observations that will have to be punch-carded. The British Meteorological Office alone hassome five million cards on file. The International Meteorological Organization advocate theadoption of the same punch-carding methods by all countries to ensure uniformity and exchange of weather data. A demonstration was given at Toronto of a type of ihrono-metric telemetering automatic station consisting of instruments which register wind speed and direction and atmospheric pres-sure. The instruments are linked to an automatic radio trans- mitter powered by special storage batteries of the low-draintype, which sends three-hourly weather observations but which under certain conditions, such as high wind speeds, automatic-ally transmits hourly. Temperature and humidity reports and amount of precipitation can also be transmitted. Radioreceiving units register these signals, which are recorded bv meteorologists. Automatic weather stations can operate ninety days witho^servicing, can be adapted lor varying climatic conditions, a3j^ are a more economical proposition than meteorological obser-vation stations in isolated districts. They proved invaluable during the war when, operating from enemy territory, theyprovided essential data for allied weather men. The Commission on Maritime Meteorology is tackling suchproblems as marine climatology, the provision of weather reports, and the production of meteorological publications. Animportant item under consideration is the organization of an international scheme for the radio reception of coded reportsfrom ships, which envisages improved methods of observation and the training of observers. EFFECT OF TRAVEL BAN ' "DEPRESENTATIONS have been made to the Bank of Eng-•*•»• land by foreign airline companies in connection with the Government's new regulations restricting foreign .travel. Therestrictions, which come into force on October 1st, require business men to obtain permission prior to using the services offoreign companies. Foreign operators complain that such dis- crimination imposes an unfair restriction on services to thiscountry. It is expected that the Bank of England will ask lor some concession to be. made, but if the regulations remain asat present planned, foreign countries will probably take re- taliatory measures. Already the effect is evident in therestriction of the number of services by foreign operators for the winter.' A.B.A., the Swedish airline, for example, who hadplanned to increase the present provision of 308 seats per week to 350 bv placing Douglas DC.6 aircraft on the routes to theU.K., have now decided to fly only DC.3 aircraft and to provide only 33 seats. MARINE BASE THE Committee formed to inquire further into the establish-ment of a marine base for the U.K. have limited the final choice to three possible sites. One of the three is the site atCliffe which was the second selection of the Pakenham Com- mittee's original choice. The establish-ment of a marine base on this site would incur enormous expense, but it would bewithin easy reach of London and is served by adequate railway connections.The other two possible sites are at Chichester Harbour, slightly east oi thePakenham Committee's first selection of Langstone Harbour, which, as in thecase of the previous selection, would appear to be capable' of being land-locked. Surface connections with Lon- don would be through either Chichesteror Portsmouth. Presumably the Navy- would raise no objections to a marinebase in this harbour. The third possible site is at the estuaryof Blackwater River, with Maldon or Colchester as the nearest towns. Againthe surface connections with London would be rather long and presumablythrough the main line to Colchester. The estuary however is wide and although onthe north-eastern side of the industrial area would appear to be at suffin<;ntdistance to be free from bad vi.-;i!,\Uty resulting from industrial haze.
