Re: Highest Flight Level Actually Flown by a 747
FWIW... On the company's 744 sim I managed to "fly" it up to FL510 (at minimum weight, splash of fuel). I then tried again, but "zoom-climbed" (an oxymoron for a 747) up to FL540, but the plane was not stable and was well into coffin corner mode. (this in no wind conditions).
