The major reason that lead Aeroflot Flight 593 to crash was the partial disengagement of the of autopilot (by the pilot's kid who was in the cockpit) which could have been avoided if the pilots were more familiar with the Airbus 310-100 or there was an audible alert.
Do new Airbus aircrafts have an audible alert in such cases now? were the old ones some how altered to implement this?
