Investigative study using eye fixation to evaluate air traffic complexity at angle of crossing

With the air traffic demand expected to grow exponentially, a more convoluted air route structure with tighter separation standards is expected to be established. This would not only have a great impact on the present tactical radar monitoring operation but also have a significant influence on the p...

description With the air traffic demand expected to grow exponentially, a more convoluted air route structure with tighter separation standards is expected to be established. This would not only have a great impact on the present tactical radar monitoring operation but also have a significant influence on the performance of air traffic controllers. Past incident reports have identified the lack of experience of Air Traffic Controllers (ATCOs) and the disparity in angle of crossing as the main reason for loss of separation between aircraft. Past research studies have discovered that there is indeed discrepancy in visual monitoring behaviour between controllers with different expertise level via the use of eye tracking technology. However, these past researches tend not to have a wide coverage on the possible air traffic situations with limited effort in trying to map the movement of the eye ball to the radar date in real-time.
