Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional linear scale displays are used for air traffic separation, then the display is simple and easy to understand, but the cognitive load on pilots increases and misjudgment occurs due to hectic information presentation
Solution Approach 1:
The patent applies parameter changes by transitioning from a linear scale to a non-linear scale for displaying separation distances. This transformation of the display parameter allows the system to represent separation distances in a way that intuitively reflects the cognitive perception of space, thereby improving pilot awareness without increasing cognitive load despite the enhanced display complexity.
Solution Approach 2:
The patent implements dynamics by making the display scale adaptive and responsive to the current separation distance. The non-linear scale dynamically adjusts based on the separation between aircraft, allowing the display to adapt to different operational contexts. This dynamic behavior enhances pilot situational awareness while managing cognitive resources more effectively.
2Measurement precision
If detailed traffic information is displayed to improve separation monitoring, then measurement precision improves, but the display becomes hectic and confusing increasing cognitive demand
Solution Approach 1:
The patent applies local quality by providing enhanced detail and precision only in the critical region where separation distance is most relevant. The non-linear scale concentrates display resolution and information density in the area where pilots need to monitor separation most closely, while reducing detail in less critical regions. This localized enhancement maintains measurement precision for separation monitoring while preventing the overall display from becoming hectic and confusing.
3Reliability
If predicted separation distance is added to the display to improve safety awareness, then reliability improves, but the display complexity increases
Solution Approach 1:
The patent applies preliminary action by displaying the predicted separation distance in advance, allowing pilots to anticipate future separation states before they occur. This forward-looking information enables proactive safety management, improving reliability of separation maintenance. The non-linear scale integrates this predictive information in a way that enhances situational awareness without proportionally increasing display complexity.

AI summary
A method and system for dynamically representing the separation for air traffic has been developed. First, air traffic is detected which requires maintenance of a separation distance from an ownship aircraft. The ground speed of the ownship, the ground speed of the air traffic and the current separation distance is determined. A predicted separation distance is calculated following a specific time interval. The predicted separation distance between the air traffic and the ownship is based on a differential in ground speed between the air traffic and the ownship and the specific time interval. The location of the air traffic, the separation distance and the predicted separation distance are all shown on a graphical display onboard the ownship. The separation distance and the predicted separation distance are represented on a non-linear scale on the graphical display.
