November 1971 THE LITHMI04E HERALD Secret paper lists Concorde weaknesses By ANDREW WILSON London Observer Serious performance limitations that make the present Con- corde virtually are tacitly ad- mitted in a confidential memorandum circulated within the British Aircraft Corporation. A copy of the with the reference number MSC is in the hands of The Observer. It consists of notes from a marketing meeting on August 30 to discuss a submission to be made to the British and French Governments concerning continued production of the aircraft. Among the facts disclosed are that the fully-developed Con- corde major alterations to engines and cannot become available for another six that if it goes ahead it will be a expensive that almost nothing can be done to improve the present and that noise measurements on the 02 pre-production plane have been Despite the report makes it clear that the makers will press their governments to step up the development programme in the hope of securing notably from Japan Air Lines and Pan-American later on. The leave no doubt if the cost of the plane will greatly exceed the figure of million pounds given earlier this year by the British Aerospace Michael Heseltine. They also admit that it will remain a political since the fully-developed aircraft will still not meet U.S. federal noise suppression requirements. Proposed improvements The marketing meeting began with a reference by the Con- corde flight test J. B. to proposed im- provements in the fully-developed known as These could include a 10 per cent extension to the wing leading edges and power plant improvements. But ac- cording to Mr. Dickens the fully-developed aircraft would not be available until the end of and would require a lot of ex- pensive development time to certify. As for improvements to the existing Mr. Dickens said there was really not much that could be done. One solution being investigated by Rolls-Royce involved a straight thrust im- but this could be achieved only at the expense of reduced engine life. The French had opposed it because it would add time to the certification which clears the plane for airline service. The French had recommended that as from about plane number 15 are now being with only nine firmly each aircraft should have an additional fuel tank to increase range. The manufacturers were also involved in weight-saving exercises as package to provide Ibs. payload improvement. said Mr. there would be no noise im- provement. Again high-lighting Anglo-French Mr. Dickens said the French manufacturers wanted a joint statement that there was a market for 30 such aircraft but BAC saw a figure of only 16. On noise Mr. Dickens said O2's disappointing perfor- mance was due to the failure of the and silencer developed by the French firm SNECMA. The French had no hope of improving the situation. Concorde's levels were now two decibels above the promis- ed flyover figure of 114 and 1.5 decibels over the 111 decibel sideline noise target. Another BAC technical M. G. said that ing all just scraping it was possible to meet noise guarantees to BO AC and Air France they could not reject the aircraft on that but it would be difficult to present the aircraft to other operators view of present 'opinion on noise throughout the New York 'difficult' According to the the meeting noted that although the U.S. Federal Aviation Authority would not be awkward until 1977 Corcorde could meet more stringent New York could be over the noise question. Mr. Wilde said he was pessimistic about noise reduction in the 1976-7 period the makers have said they hope to start selling the plane Pressure might be put on but it was questionable whether the governments would agree to the very high costs involved. The French considered the situa- tion insoluble and a political whereas BAC considered it must be solved technically at all costs. As for the long the French estimated that in there would be a reduction of 11.7 decibels on the current total approach and sideline of 345 decibels. But this would still be 15 decibels above the maximum laid down by U.S. federal aviation Part 36. On the question of what to do between now and Mr. Wilde said the French wanted BOAC and Air France to have the existing model Concordes in service as quickly as possible. But BAC's need was to pressure the governments to produce the planes at an acceptable industrial i.e. six a year as compared with the present eight. Mr. Dickens said the French were confident that with the tank modifications the 'plane would be acceptable to Pan- American and Japan Air Lines. They also felt that the public would learn to live with supersonic noise and if BOAC and Air France could operate it it would be reasonable for others. Concorde's sales E. H. com- mented that in order for the airlines to do this BAC would have to write a contract acceptable to the U.S. and the deputy marketing Air Vice-Marshal I.D.N. said the government would have to agree to fight the case on noise levels with the U.S. authorities. in a section of the report headed Mr. Burgess is quoted as saying that BAC should put up a case for government support for a fully-developed aircraft on commercial grounds. Mr. Burgess said BAC now needed to spell out to the British Treasury what it was so that the government could judge what way to put its cash at risk research and subsidized sales and so on. The makers have had a clear indication from Japan Air Lines what it wanted mance on the Anchorage-Tokyo flight viable economics and an acceptable sales price in that and this needed costing. Very high cost On Mr. Burgess said it was apparent that with escala- tion the cost of developed aircraft would be very high. Other ex- ecutives present said government help to buyers to meet the high investment cost of Concorde was essential. H. G. said this was well known as but the corporation did not want to tackle the government on the price of the aircraft other sales this Apart from the fact that the government may question BAC's confidence about American and Japanese the report highlights the complication of what to do with the aircraft still being built. It says the meeting agreed that BAC must put to the govern- ment the case for of these aircraft presumably at give-away prices. But Mr. Wilde told the meeting that the in return for sanctioning continued would probably insist on their being sold commercially. At another point the contain a cryptic sentence referring to the need to meet a sudden demand for more Con- cordes the aircraft Portuguese schooners sail home Old hand Silas inspects an ornate hunting knife in his North B.C. home.

The t of the PortufueM fitting known ai the White hu left this ancient seaport for their homeland for another year after almost nine months of fishing cod on the Grand Banks and other banks rang- ing as far north as the Green- land shores. The Portuguese schooners make up the world's but com- mercial sailing fleet but their days are numbered. For cen- turies the sailing schooners of Portugal have plied the wa- ters off salting in fish for the markets of Lis- bon.

But now they're the last of a tough line of ship because stern trawlers and other mod- ern craft are taking over. In February and early March a of 15 of the schooners put out from Portu- for the Grand Banks and and it's d year. Only 12 of the ships are among the homeward bound. Three were lost to fires al- though their crews were saved by sister Angelo De manager of the Portuguese Seamen's Place in St. said the vessels and what cargoes of fish they had accumulated represented a loss of mil- lion. The fleet lost only one crew member this season it was a bad year Mr. De Silva said. He was not sure how much fish the dozen' homebound ships carried the catch was not as good as last Depleting stocks of the only species the Portuguese will outdated fishing and almost-total de- pendence on sail power is making each season less and less profitable for the Portu- guese.
