Re: Highest Flight Level Actually Flown by a 747
 

I seem to remember an incident with a china airline 747 that was kept in a climb attitude until it stalled (full of PAX, ouch)…

Any idea what altitude was reached ?

Don't think the Chinese 747 over SF was going amazingly high, as much as it only had 3 donks working, but the AP was in altitude hold at the time and tried to force it to stay at an altitude it couldn't cope with.

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).
