THE DAY “GOD” FAILED OR OVERTRUST IN AUTOMATION. A PORTUGUESE CASE STUDY

The increasing development of computer based technologies open new horizons in task automation, helping pilots and air traffic controllers to carry out the analysis and resolution of an increasing number of cognitive tasks, in complex working environments. However, there is a general agreement that cognitive automation may lead to overtrust, complacency and loss of the necessary operational situation feed back, as the basis of the mental model refreshment which, in turn, allows for the maintenance of coherent situation awareness of all the operational processes. The case study reported suggests there is a dimension to be followed in human machine integration, which is beyond the technological deterministic approach of human machine interface design, and calls for a better human comprehension of system nature. The human comprehension of this dimension, which we introduce as the technological factor, represents the basis of systemic self-constructed situation awareness, in a real human centered development.
