G/A due no FLARE? then TO/GA

ok, just my thoughts on slayerdude's NO FLARE followed by TO/GA "facts":

FLARE activates between 60 and 40 ft radio alt.

so, if you watch the modes you should notice it's not there by about 30 or 20 ft, which gives you enough time to disconnect and land manually or
if you don't watch them, you'll notice it on impact with the runway.

The TO/GA weren't pressed in the air, as this would have ended in a go-around, maybe with a brief touchdown during the procedure, but they would not have landed from this situation.

now if you then press TO/GA after touchdown you'll get nothing, as TO/GA is inhibited and Autothrottle is not available. Only way to reject a landing after touchdown is manually add thrust and hit the TOGA after getting airborne again.

So unless there was a severe malfunction (of TOGA inhibit, A/T inhibit, and you'd need 1 Eng failure followed by a Thrust Asymmetry compensation failure) I can't understand how pushing the TO/GA leads to a runway excursion....

Do you have any more details, as so far this TO/GA "fact" only creates more confusion...


from the picture it looks like a slow departure to the left followed by a violent correction to the right, not an immediate right turn...

so maybe a undetected no "ROLLOUT" only corrected after it got apparent that she won't come back to the centerline all by herself?
