Squatter - Thanks for the timeline correction. The only point that I was making was that the A320 predated the other variants by many years and thus Airbus`s view about Conf3 + FULL certification may have changed.
As to the other `colonial` poster - what has the L1011 or B767 got to do with this post!! If you insist on `willy waving` then I am sure you will remember that the DH121 aka Trident, Belfast, VC10 not to mention the B747 had similar capabilities!
