The increase in automated tasks in the airline cockpit has changed the role of the crew, from an active one to an apparently more passive one, supervising and managing automated systems. Many believe that this fundamental change in role has not received enough attention, and that it may have led to crews not being adequately trained to perform their new supervisory and management tasks. This scenario could have resulted in a number of accidents and incidents attributable to human factors. The transition from conventional aircraft cockpits to state-of-the-art glass cockpits will have to take into account human factors, which have not been properly addressed in training schemes so far.
