FLIGHT, 4 January 1951 CIVIL AVIATION NEWS 21 TEMPORARY ACCOMMODATION : Siam Air- ways and Malayan Airways are both using marquees at Butterworth, Malaya, for passen- ger reception while the nearby runwt Penang Island is beingj>epOiiea. I lie to return to Penang in April. GOOD PROSPECr B.O.A.C. THE encouraging results of B.O.A.C.'s operations for the yearended October 31st, 1951, were last Sunday announced in a New Year message from the chairman to the Corporation'sstaff. Sir Miles Thomas revealed that the annual deficit had been" reduced, as compared with the previous year, from£8,400,000 to £5,700,000. Annual output per employee had risen from 6,300 to 8,300 capacity ton-miles, while revenue peremployee rose from £900 to £1,200. B.O.A.C. carried 180,000 passengers in this period, an increase of 30,000 on the previousyear, and one which was achieved with an increase of 20,000,000 in the total capacity ton-miles offered. Of the prospects for the current year—the occasion of theFestival of Britain—Sir Miles Thomas thought that given reasonably suitable world conditions, B.O.A.C. would un-doubtedly achieve good results. COCKPIT CALCULATOR A COURSE-AND-DISTANCE calculator which should**• prove useful to many private pilots (and, no doubt, some commercial pilots also) has been designed and produced byShell-Mex and B.P., Ltd. Intended primarily as an aid to private flying under V.F.R. The pilot's calculator developed by Shell-Mex and 8.P., Ltd. (and scribed above), is seen to be a compact and neat d£ s|ze ; ot the same time it is considerably easier similar instruments designed for cockpit use. conditions, it consists of a double-faced engraved plastic square,of convenient size. On one side a rotating disc provides a quick reference for the courses and distances to nearly all Britishcivil airfields likely to be used, while on the reverse side a circular section of map may be inserted to give an indication ofthe first ten miles (or 20 miles—according to the scale used) of the course to or from the base airfield. A table of conversionfactors is also engraved on the instrument. The calculator has been used by Shell pilots for a number ofyears and has proved so useful that the company has decided to make it available to alLat a cost of 10s. T.W.A. BUYS THE "1049" HP.W.A. has announced its intention of purchasing ten new •»• L-1049 Super Constellations from the Lockheed Aircraft Corporation. They will cost nearly £6,000,000 and are scheduled for delivery in the spring of 1952. The company is already operating more Constellations than is any other airline and, when delivery of the new aircraft is completed, T.W.A. will have a fleet of 76 machines of this type. The Super Constellation (notes on which have appeared in recent issues of Flight) is 18ft longer than th; standard version and has a gross weight of 120,000 lb. The increased a.u.w. is, in part, offset by the additional power from the ejector exhaust system fitted to the Wright C18CA-ls which will power T.W.A.'s aircraft. Maximum cruising speed at normal a.u.w. is just under 310 m.p.h. In addition, the Super Constellation has an opera- tional ceiling 5,000ft above the present limit for the standard versions. For domestic operation the " Super Connies" can accommodate up to 75 passengers, while for transatlantic ser- vices it is thought that passenger capacity will be about 60. Other characteristics are similar to the L-749A. It seems most likely that the basic 1049 version will be used —at least initially—on T.W.A.'s domestic routes and that further orders may be for the L-1049C with compounded engines; for these latter machines a much later delivery date is being quoted. Even when powered with the CA-1 engines the 1049 will have a better performance than most other types outside the pure jet field. With a capacity payload of approximately 17,000 lb, a maximum range of 3,300 miles is quoted with a three-hour reserve. With a reduced payload of 12,250 lb, still-air range with reserves is 4,200 miles, with a block speed of 300 m.p.h. for the London-New York flight. The announcement of the T.W.A. order brings the present 1049 backlog to about £18,000,000. Other orders already made known are those for K.L.M., Eastern Airlines and the U.S. Military Air Transport Services. PAN AMERICAN'S TRAFFIC RECORD HAVING enjoyed—like so many other operators—a full shareof the increasing prosperity which was apparent throughout the world's air transport industry last year, P.A.W.A. recorded agreater volume of traffic than ever before in its 24-year history. The year's work involved the carriage of more than a millionpassengers in addition to 50,000,000 lb of cargo. This record—which does not include work done for the armedrces—was all the more notable in that it was achieved at H "when one-tenth of the company's four-engined fleet was
