Yes. That's also what I remember. As far as I remember, it was an AF-A332 (330-200) and they were on the return flight back from Rio Galeao SBGL to Charles de Gaulle. You wonder why somebody with my nickname knows all these names and codes? Well ... the reason is the nickname..
And during the first hour, everything on board the AF-A332 was completely uneventful. So they climbed to a very normal cruise alt. Then, somebody detected quite severe conditions ahead. And I don't quite remember if they had wxr radar on board. Sometimes a sheer look through the window is enough. Thus, they decided to avoid what they've seen, heavy clouds and lightnings. A/P was disconnected, and they tried to climb again, right?
And then it became fatal. Let's say with FL360, they decided to climb again, manually. Since I own Randazzo's LH-B744 simulator, I know that this is special. Especially if only one hour or clearly less than 50% of the distance is behind you, on an intercontinental flight.. The PFD commands you to fly fast enough. But even in a 747 you don't reach vmax when you are that heavy. In case of a 747, four N1 numbers are a quite good warning..
And then you should NOT excessively pull the elevator, please..
The fmc even gives you cruise alt recommendations for almost every phase of the flight, if you sit in a B744 simulator. Which imho is calculated with your precise TOW, FOB, and Fuel Flow in every single engine. Sometimes I say that a B744 herself teaches me how to get the best out of her.. FL360 is a quite good number for this flight phase. And then climb again, manually? Hm.
I assume that all this somehow is connected with this new topic here.. Well, sad.
2017 was a year without 1 major aviation incident! In contrast to 2018, obviously.
PS: As you certainly have perceived, I've never used VNAV, not since I fly Randazzo's Finest, as I call her. I am a fan of personally sitting at the elevator, and, at the throttle quadrant, of course. If you don't know how far you can pull after you've pushed the thr, bad things can happen...
