Checking the book last night, I discovered a short discussion on different regulatory requirements for the ASD case. FAR 25 amendment 42. What's prescribed in it, what applied before and how it was superseeed. First read on the subject.
How would this apply for 767-400 v. s. the Dreamliner? Is the - 400 really pre-amendment? What about the 747-8?
