Waa... Asseline was innocent... Norbert Jacquet is a great man... Airbus are evil and hate pilots...
There is *nothing* wrong with the sidestick for training purposes - it did just fine in the F-16 trainers, long before one was ever fitted to an A320. There is no proof that the dual input was what caused the excessive bank angle either, but the Airbus-haters will never accept that.
The need for feedback-linked controls went out with the introduction of RAT-powered hydraulics - you don't need two pilots "feeling" the aircraft and what each other are doing if it's all being done by actuators with no manual reversion. If the LH Captain messed up by going against training and failing to press the override switch before taking control, or even by having his F/O do an approach in weather that nasty in the first place, that is his lookout and no-one else's.
