LH needs cargo capacity as well. This might be a problem with the XLR. LH is a full service carrier, not only for the passengers but also for cargo. Lots of those destinations in Africa and the ME would be in XLR range. But those destinations are cargo heavy flights als well. Therefore cargo might b...Jump to post
Airports are constantly modified. New regulations, new aircraft and whatsoever requires a modernization of airport infrastructure all the time.

Good comparison. I suppose they will change operations similar to Gatwick once more runways have been constructed.

One would hope that the fact that the captain's AoA display had gone all blue while the FO's was still ~40% brown would also be a clue.

From LH's comments it looks like all their A346 will be replaced by A359. So I don't think they feel first class is required on those routes anymore. Replacing A346 with A359 does not mean they will be used on the same routes. They might rotate aircraft as well. It is way to simple to say that A359...Jump to post

Previous generation large jets (not fly-by-wire) have cables from the control columns to a bellcrank that directs a PCU to deflect the control surface as required through the control column movement.

So, does this leave only spatial disorientation and confusion then as the initiating action? Can others see any other issue that would fit what we've been told?
Stall is AOA dependend. Not speed!
You can stall an aircraft at any speed.

BUSS is quite simple actually. It uses raw AoA from the vanes. There is no speed displayed, just an AoA range. Just keep it in the green.

FDR has been read out. 1800 paramters from 19 flights.
It looks to me like you're throwing irrelevant / inaccurate information around in an attempt to confuse the reader. Was this aircraft equipped with the optional AOA sensor? I doubt it.

Because it could only record data from the static port / pitot system which is suspected of being the failure point in the previous flight. The FDR will record much more than that.

Wake turbulence at cruise altitude is quite special. I once experienced a sudden roll up to 30° right bank. The roll rate was impressive, almost instantly. The wake was produced by an A330.
