OBJECTIVE EVALUATION OF HUMAN PILOT OPERATIONS IN WIND SHEAR USING PSYCHOPHYSIOLOGICAL MEASUREMENTS

摘要

With the development of onboard Light Detection and Ranging (LIDAR) systems, it will be possible to measure the wind velocity field up to several miles ahead of an aircraft when flying in clear air. We investigate how this information can be relayed to the pilot in a meaningful way, in order to reduce accidents, incidents, or inconvenience caused by strong turbulence and wind shear. In this paper, we will focus on the objective evaluation of the pilot’s use of such a new interface, through analyses of the pilot’s control actions, as well as psychophysiological data obtained from an eye-mark camera, an electrocardiogram (ECG; heart rhythm) and electroencephalogram (EEG; brain waves). We present two preliminary experiments with 3 subjects each. The first experiment showed promising results, but suffered from significant artifacts due to the fact that subjects were expecting the occurrence of a discrete event Fig. 1 Main accident causes in Japan between 2004 and 2013 (by domestic air carriers that operate aircraft with 100 or more passenger seats or with a maximum takeoff weight of more than 50,000 kilograms) [1].(windshear). The second experiment used a secondary task, which provided additional and valuable data, but probably obscured part of the changes in the measured psychophysiological parameters.
