Abstract :

The goal of this research is to develop a method that can predict pilot task demand load during approaches. This paper presents the results of a flight simulator experiment that aimed to give a first indication of the factors related to the approach trajectory that influence pilot task demand load. Analysis of the flight simulator data showed that the following factors influence pilot task demand load: the energy rate demand during the last parts of the approach, localizer-intercept speed, the distance available on localizer-intercept heading, the lineup distance, the required altitude at the final approach fix, localizer-intercept angle, and whether the approach is stabilized at 1000 ft. The results of the flight simulator tests are also used to validate the predictions of a Monte Carlo simulation. The Monte Carlo simulation predicts whether it is possible to meet the constraints at the waypoints and whether it is possible to achieve a stabilized approach, which are two of the factors that were shown to influence pilot task demand load. A significant correlation was found between these Monte Carlo predictions and the flight data from the flight simulator experiment. DOI: 10.2514/1.C031188
