I only flew the 747 Classic - what Intruder says about the max 5 degs of bank is correct, as also is the fact that it could be landed with the drift still on and, as he says, on a wet runway the 'self alignment' is hardly noticeable. But I still think it is better to remove the drift before touchdown. My only quibble is about kicking off the drift. Too many pilots talk about kicking off the drift when all that is needed is a gentle squeeze on the rudder. And in view of what Intruder says I would add that is better to remove too little drift than too much!
