>From what I can find, the 747 is supposed to be able to cruise at around 490 KTAS between FL280 and FL350. At FL280, 490 KTAS true would be about 314 KIAS; at FL350, it would be a bit lower, but you're getting near the tropopause and things get screwy. At FL180, 314 KIAS would give you only 427 KTAS. If you're trying to fly at 490kt *indicated* at FL180, then you're pushing something like 666kt true -- it would be no surprise that you'd have to push the nose down and abuse the engines to maintain that.
