Rob21:
The computer on-board TAM's A-320 went in to a "stubborn mode" (DON'T MATTER WHAT YOU DO, I WON'T GIVE YOU GS).
Where do you get this from? The computer would cheerfully have given them ground spoilers if the thrust lever was in the correct position. It would also have stowed the TR, dropped the spoilers and given them TOGA power if they had shoved the levers forwards into the TOGA position. Whether this would have given them enough thrust soon enough to get them back into the air we'll never know.
There's a fundamental minsunderstanding of what the A320 computer does and does not do going on here. It does not 'prevent' the pilots from doing anything and never has. The alpha floor protection was designed to prevent the aircraft from inadvertantly falling out of stable flight when above 100ft, but that's about it for overriding manual input.
