Genuine questions, but just speculating on a what if scenario.
Given that the Airbus is a fly by wire, side stick controlled aircraft and probably climbing on autopilot at the time of the incident, what would be the effect of a full excursion rear or forward movement of one of the side stick controllers.
Could a pilot inadvertantly knock the sidestick control full travel? Very unlikely I know, but would the aircraft respond immediately to the sidestick input, dump the autopilot and move the elevators full travel or would the built in protections prevent that happening? My understanding is that the controllers remain in position and do not self centre, so it might take a couple of seconds to recentre the control. Would that be sufficient to damage the aircraft?
Given that the repaired tail section might be slightly weaker than on an undamaged aircraft, could a rapid control movement cause separation?
