3.25 to 3.49 Display layout in automated flightdecks may change the traditional instrument scan pattern, leading to loss of skills which may be needed upon transitioning to conventional aircraft. Pilots must use automation in a manner not intended by designers to get desired results or to avoid undesirable consequences, increasing pilot workload and opportunity for error, and may have unanticipated and undesirable side effect. Automation design prevents the device from performing a function that seems reasonable to the pilot, requiring the use of alternative strategies which may increase workload and the opportunity for error.
Automation changes the role of the pilot from that of a controller to that of a supervisor.
Because most pilots are not adequately trained for and experienced in this role, errors result.
