Flight Control Laws
With regard tot the control laws:
Both in normal and alternate law1 and 2, both elevator and THS are programmed to produce a certain G value. This would be 1G when the side-stick is in neutral. So when there is aft side-stick, both elevator and THS try to deliver more than 1G.
Only in direct law the THS is controlled manually through the trim wheels.
The clue of the THS position would be the scale next to the trim-wheel, but this is used only prior flight. In fact, the THS is not in the mind of an Airbus pilot during flight.
I absolutely don't know what I would have done in that situation, because my brain would be in overload and also blurred by all the natural drugs in my blood....
I suspect there will be increased focus worldwide on the training of 'loss of control', 'unreliable airspeed' and use of THS.
