Where do you draw the line? The manufacturer seems to be >the best authority available, and Airbus lumps the A300 and A310 >together. The key is the Type Certificate. All 737s have the same type certificate (not the same as a rating - all 747s use the same type certificate, but the 747-400 has a different rating requirement). The DC-9/MD-80s have the same Type Certificate, as do DC-10s and MD-11s. Presumably the same is true for A300/A310 airplanes. In the last year or two, things have gotten a bit mushier. I'm clueless about the A330/A340 Type Certificates. I'd guess it is much like the Boeing 757/767 Type Certificate, but I don't have any data. The A321 shares the same TC with the A320, and with the A319 if/when it is built. Another interesting question is the Russian aircraft. Tu-204, Il-96, An-124, etc. For those into the really complex, there is still the BAC 1-11, with a UK Type Certificate, and what used to be a Romanian Production Certificate, but without BAC participation, one wonders if the TC will continue to be recognized by Western regulatory agencies. -- Terry firstname.lastname@example.org "Anyone who thinks they can hold the company responsible for what I say has more lawyers than sense."
