Quote from post #10. "The 757 and 767 don't share a Type Certficate."
Spelling apart (see me after), All my recurrency checks on the 757/767 were done in either a 757 or 767 sim, whichever just happened to be available at the time. I, and all the other instructors, were under the impression that they were on a common type rating. Maybe that is not the certificate referred to, but it was treated by us to be a common type (even if it actually was not). (Plenty of more anecdotal evidence of that in my head if you want!)
