Engineering Contradiction Analysis
1Productivity
If flight sequencing technology generates abstract timing suggestions, then the arrival management system can optimize flight sequencing and allocate time for each key point, but the air traffic controller finds it difficult to guide the aircraft strictly according to the sequencing suggestion
Solution Approach 1:
The patent introduces a visual spatial position reference target as an intermediary element between the abstract timing suggestion and the air traffic controller's guidance action. This visual target converts the temporal sequencing information into a spatial reference that the controller can easily understand and use for real-time aircraft guidance, thereby bridging the gap between system optimization and operational ease.
Solution Approach 2:
The patent transforms the timing suggestion from a temporal dimension (abstract time values) to a spatial dimension (visual position reference target). By projecting the sequencing time onto a visual spatial target, the controller can intuitively grasp the required aircraft position and timing requirements, making the abstract temporal constraints concrete and actionable in the spatial domain.
2Measurement precision
If the flight sequencing suggestion is converted into a visual spatial position reference target, then the air traffic controller can guide the aircraft more accurately, but the system complexity increases
Solution Approach 1:
The patent segments the flight path into multiple key points (e.g., entry point to terminal area, intermediate points, runway threshold) and generates separate visual spatial position reference targets for each key point. This segmentation allows the complex timing requirements to be broken down into manageable spatial targets, improving guidance accuracy at each stage without overwhelming the controller with a single complex instruction.
Solution Approach 2:
The patent creates a visual copy or representation of the aircraft's expected position at future time points. Instead of presenting raw timing data, the system generates a visual target that replicates the spatial information derived from timing predictions. This visual copy makes the timing requirements intuitive and easy to interpret, improving guidance accuracy while keeping the interface simple.

AI summary
A time-space conversion method of flight sequencing information aims to solve a problem that a flight sequencing suggestion generated by an arrival management system has poor effect in practical application due to abstract characteristics, comprising: generating a sequencing time and a delay suggestion of a flight in each key point in a terminal area and each runway by using a flight sequencing technology; predicting a flight status of the flight according to a current position and 4D trajectory information of the flight, and filtering a delay-consumed flight segment, and on that basis, generating a flight segment delay allocation strategy with reference to an aircraft performance and sequencing information, and obtaining a flight segment delay allocation result; and generating a visual spatial position reference target according to the flight segment delay allocation result and an operation deviation limit.
