Abstract: Guilt! : A word which disrupts accident investigations. In the scenario of aircraft with high degree of automation control which resembles computer consoles, point to the need for further research focused on possible conflicts between the "human logic" and "logical automation" checked in control systems for aircraft. It is very important to consider that the logic of automation was also drafted by pilots, so that this assumption is difficult to validate. A pilot in command of the Airbus blurted that "modern technology was withdrawing men of cockpits. This happened with the radio-telegraph when they got the new communication systems called SSB and VHF. But from there, the pilots were more burdened with the task of transmitting operational information and logistics companies, diluting attention at critical moments of the flight, in congested terminal areas. Also happened with the navigator when new systems arise like Omega and Doppler Radar. Over a sequence of operations adjustments and manipulations more equipment were transferred to the pilots on this occasion, adding to the known and the complex and overloaded duties of these professionals. This also happened with the mechanics of flight (the third man in the cockpit), when computers arrived. Until the 70s there was a work station flight engineer.
