Abstract:In conventional approach procedures for aircraft the final segment of the flight path is straight. With the introduction of curved paths in the final approach — intended to expedite air traffic — the mental workload for the pilot in flying (or monitoring the autopilot) has become topic of research, since it can be argued to have become larger due to increased procedural complexity. To investigate whether this is the case, measures of flight safety, as affected by the human pilot, have been developed. A model of mental effort, mental workload, performance and associated physiological indicators has been discussed, in order to provide a justification for the different measures. It turns out that the 'time to crash' quantity and elevator control power are indicative of levels of flight difficulty. This level was varied in a Boeing 747-400 flight simulator by adjusting the meteorological conditions during the approach phase of flights. These measures have also been applied to flight training data and shown to be related to the pilot's performance level. Accordingly, they serve as valuable tools for assessing a pilot's flying qualities.
