Ok. I'm a bit confused here. Let me get this straight the 330/340 were not a common type. So one would need to have done a CCQ. But the 330/350 are just as the 787/777. But the question is have is that do the regulators require extra training or is that done at the behest of the operator? Did those who flew 330/340 have it on their license on separate lines as separate types or was it combined on one line as 330/340?
