you want to take over:
simple revert to Speed Heading V/S or any other selected modes (op clb,etc) if that doesn't help there is a red push button you usually use to disconect the automatics isn't?
For CONF iture: The accident you refering to, I don't knw all those details, but did you know that the captain was trying to show how smart was the a/c demostrating Alpha Floor but forgot this:
ALPHA-FLOOR PROTECTION
Alpha-floor protection automatically sets the thrust at TOGA thrust, when the aircraft reaches a very high angle of attack.
The Flight Augmentation Computer (FAC) generates the signal that triggers the alpha-floor mode. This, in turn, sets TOGA thrust on the engines, regardless of the thrust lever positions.
The FAC sends this signal when the angle of attack is above a predetermined threshold, that is a function of the configuration.
In CONF3 and CONF FULL, this threshold decreases as a function of the aircraft deceleration rate (down to - 3°).
Alpha-floor is available from lift-off until the aircraft reaches 100 feet RA in approach.
I repeat, errors tend to be uman in any case...
If you comand Toga the A320 will go around!!! Look at the Tap video (the one about the xwind) they applyed Toga almost when they were already on th GND if there is any delay is caused by the Spool up time common to all A/C (the 737 and the A320 got almost the same CFM)...
If I am flyng the a/C and something doesn't look right I would take over no matter which a/c we're talking about..
