I seem to remember the standard of "English" used in the Airbus manuals was frequently pretty poor and had clearly not been proof-read by a native English speaker.
The americanisms were irritating as this is a European aeroplane (as opposed to "airplane") and it really ought to use real English. Even the American version was of poor standard and sometimes severely garbled in translation and could often cause considerable difficulty in divining meanings - to the extent that non native english speakers would be in real trouble making sense of it, and that is inexcusable in a technical manual. It had the stamp of French or Germans translating it and assuming as they so often do that their command of English was so perfect it didn't need proofing. As ever in such situations they were wrong.
As a German once said, "You Eengleesh, you know **** nussingk! Vee Shermans, vee kow **** all!"
