Especially emissions of certain colours of light at certain times affecting the Pilots circadian rhythms and cause eye fatigue – which is recognised to have an impact on Pilots performance. This research paper complements the current study and measurement of stress, fatigue and human factors with respect to increasing artificial light intensity experienced by Pilots on the Flight Deck. For the purpose of our research, we decided to use eye monitoring technology to record eye movements to determine the pilot’s performance. Eye monitoring provides data on the number of eye movements, fixations and the durations of these.
By analysing the observed eye parameters such as saccadic eye movements, blinking, eye fixation and dwell time, under different light conditions, the authors concluded that there was a direct influence with the intensity of the instrument panel backlight, especially during night flight conditions. The results of this eye monitoring analysis supports the hypothesis that visual fatigue depends on backlight intensity levels. Moreover, the backlighting of the instrument display panels, during a flight influence the pilot via visual fatigue. Even Flight Deck environmental conditions could be additional parameters.
