Joseph Reid wrote I have just located a page of Aerospatiale that gave specifications of their Airbus A340 lines. Although I accessed the French page, all the specifications were given in feet, pounds and US gallons. That does not prove that the Airbus line was designed in I-P units, but merely that I-P units were used in the WWW page to enable comparison to be made with competing US products. See http://www.eads-nv.com/xml/fr/businet/airbus/airbusfam/a340/ta340500.xml *** Now Airbus has secured enough orders that they can start displaying values in SI. http://news.bbc.co.uk/hi/english/business/newsid_1402000/1402496.stm Once if they start it, then Boeing will follow it in displaying and using SI. Always the competition forces the companies to move to superior techniques. Madan __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
