@747-8driver: Yes, some may call your landing fuel a bit low, the tank and hyd. pump on 748(F?) may be very different from the 744. I've never accessed the 748 books and I don't know. If you are within Boeing and company SOPs, and have enough to reach a weather alternate, go for it. For the long legs that you probably fly, you need most of that fuel simply to arrive at TOD. If the older 15 min rules still apply to your fancy new Big Bird, work-arounds learned on older aircraft may be of help. I don't see a problem.
