JEPPESEN ATPL BOOKS
Hello, i'm starting the ATPL course and i'm wondering if there's some important difference between Jeppesen edition 1 books (2004) and Jeppesen edition 2 (2006) as a friend of mine would lend the entire set (2004) to me for the duration of the course. Anybody knows if they are still valid or maybe there's something updated on 2006 set?
Thank you
