7 March 1952 I.A.T.A. TO DISCUSS LANDINGS AT the semi-annual meeting of the I.A.T.A. Technical Com-**• mittee, held in Madrid during January, two important subjects of concern to international airlines were chosen for ultimate discussion at the I.A.T.A. Technical Conference to be held in Copenhagen from May 5th to 16th. Consideration will be given to all factors affecting approach and landing of aircraft and there will be an exchange of views on future airborne radio equipment. Over 200 technical representatives of airlines, governments, manufacturers and research laboratories are expected to attend. It is hoped to develop and co-ordinate an overall picture of these two subjects in order to assist development now going on in their various individual phases. The Technical Conference will also have a full agenda of com munication, engineering, meteorological and operation matters. The chairman will be Capt. J. C. Kelly-Rogers of Acr Lingus. B.O.A.C. WANTS STEWARDESSES CTEWARDESSES getting engaged or married at the rate of *** one a week have made it necessary for B.O.A.C. to seek replacements. More than 800 girls anxious to fill the gap have applied to the Corporation for employment, but less than three per cent of those interviewed have been finally accepted. The Corporation still has a number of vacancies for British girls between the ages of 21 and 35, "of smart appearance and with a pleasing and well-developed personality." Stewardesses receive £5 17s 6d a week plus £2 a week flying pay when they begin full flying duties. Maximum salary is £7 7s 6d plus flying pay and out-of-pocket allowance when out of the United Kingdom. T.W.A.'S TOURIST PLANS TX^ITH virtually all T.W.A.'s new tourist services already fully " booked for July, the company's sales vice-president, Mr. E. O. Cocke, announced that the airline will begin the new low-cost flights with daily schedules on May 1st; the inaugural flight is already completely booked. Revealing more details of the tourist-class flights, Mr. Cocke said that London will be served with four flights a week in each direction, and there will be three services weekly to Paris in each direction. Further, T.W.A.'s several daily domestic tourist flights from nine major cities across the U.S. will connect at New York with international tourist flights, via one airline, from such cities as San Francisco, Chicago, St. Louis and Pittsburgh to their European counterparts. WHITE TOPS OR CABIN COOLERS? D URING the past few years white-painted roofs for airliners operating in warm climates have become such accepted practice that a recently expressed contrary view is worth mentioning. The rebels are Trans-Canada Air Lines, who remark in a recent news-sheet: "We now know certain facts: (1) During conditions of hot sun and low wind an aircraft with a white top does not heat up to as high a temperature as one witfi an ordinary aluminium top. The actual average difference appears to be about 10 deg. F. White tops do not cool the aircraft. They only prevent it from becoming quite as hot as it would under ordinary con ditions. (2) We also know that the major airlines in the United States, with the exception of American Airlines, are now either using or propose to use white tops on their aircraft. (3) Certain people prefer the appearance of aircraft with white tops to those without. (4) The cleaning of a white-painted surface is also less time-consuming than the polishing of an aluminium metal surface. "On the other side of the ledger we also discovered certain features :—(1) The 10 deg. F. temperature-reduction mentioned above is very considerably reduced in cases of appreciable breeze where the doors of the aircraft are left open. (2) The effect of the white tops disappears once the aircraft starts to move at a reason able rate of speed. (3) The cost of painting the tops of our aircraft white down to the window line would be about 200 dollars per aircraft, because we would have to repaint the 'Trans-Canada Air Lines' along each side of the aircraft. (4) The empty weight of the aircraft would be increased by about 50 lb. (5) The cooling effect we get from our cabin fans is considered a more effective method of providing passenger relief from heat than the small temperature drop which we feel white tops will provide. American Airlines, the other major operator without white tops, has cabin fans in stalled similar to our own. (6) We also have, at Toronto and MOLE'S METHOD DISCARDED : A good idea of the vast engineering problems associated with the construction of a large international airport is given by this recent photograph, showing the building of the four-lane tunnel which will link the central terminal area at London Airport with the Bath Road. It is being made on the "cut and cover" principle and will pass beneath No. 1 runway, which will be re-opened on completion of the tunnel. 279 Montreal, aircraft ground-coolers which are more effective than those of any other operator. "With all the above facts facing us, it was necessary to come to some decision regarding white tops on TCA aircraft. It must be appreciated that hot weather conditions bother us only for about 10 per cent of the days of the year and about half the flights on those days. To improve conditions to a varying degree for those flights we would have to spend 10,000 dollars and carry 50 lb of excess weight round for the other 95 per cent of the flights. The payload on the North Atlantic and on such domestic flights as Moncton-Montreal and Lakehead-Winnipeg is a critical item. "It is apparent that personnel of our Company's stations are now well trained in the prudent use of aircraft fans in keeping aircraft conditions at a reasonably acceptable degree. "We have, therefore, decided against painting the tops of TCA aircraft white, and feel that, since we have two units of the most efficient aircraft-cooler available, the ro,ooo dollars it would cost us to go ahead with the project can be spent better at some future date if put towards the purchase of additional cooling units." BREVITIES FOR the first time in its 29-year history, Sabena has carried more than a quarter of a million passengers in one year—to be exact, 260,674 passengers in 1951, a 33.3 per cent increase over its 1950 figure. Freight traffic in 1951 rose by 76 per cent. * * * An Air France Languedoc on the Tunis-Paris service crashed on taking off from Nice last Monday j all on board lost their lives. Early reports stated that two engines were put out of action when the aircraft hit a flock of birds. * * • A B.E.A. Elizabethan aircraft was due to make a proving and demonstration flight this week from London to Geneva, Milan and Nice. Further flights will shortly be made to Zurich and Vienna and Copenhagen and Stockholm. * * * President Truman has instructed a Presidential Commission to inquire into airport and airport control conditions at Newark, New Jersey. The Commission, headed by General James H. Doolittle, began its investigation on February 26th. * * * The Minister of Transport and Civil Aviation, Mr. J. S. Maclay, in answer to a question, said in the House of Commons on February 27th that he was discussing with those concerned the possibility of reserving a site at the South Bank as a London helicopter "airstop." * * * The operations of Scandinavian Airlines System for the fiscal year, October 1st, 1950-September 30th, 1951, showed a net profit of £175,104. Gross income was £12,672,965 and total expenditure £11,302,827. £1,195,034 was deducted for depreciation. During the year 500,000 passengers, 17,000,000 lb of freight and 5,000,000 lb of mail were carried.
