Handling the big jets has a decent explanation of dutch roll, you can find it on amazon or other book websites, the latest issue also has some interesting stuff on the 747. I just had the 1st interview, just got a call for the second, the training captain at the interview was really big on performance questions. Ie: what is v1, vr, v2, why are they what they are, what are they predicated on. Why is the split on the 744 between v1 and vr larger on the 744 than a small corporate jet, (my current ac) he was also big on segment climbs, diff between stopway, clearways, and what exactly is balanced field length etc... The performance section in ace is a pretty good help. hope this helps....
