Flight Data Processing Unit ADS-B Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic control systems do not fully utilize Automatic Dependent Surveillance-Broadcast (ADS-B) information, limiting the coupling of flight plans and flight paths, and thus affecting the efficiency of aircraft arrival scheduling.
Innovation Solution
A method that involves a surveillance data processing unit fusing radar and ADS-B information to generate a system track, which is then received by a flight data processing unit to couple the flight plan and flight path, allowing direct receipt and utilization of ADS-B information by the flight data processing unit, even if not processed by the surveillance data processing unit, and using this information to display the current flight state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the flight data processing unit only receives processed system track information from the surveillance data processing unit, then the system architecture remains simple and centralized, but ADS-B information cannot be fully utilized and coupling coverage is limited
Solution Approach 1:
The patent segments the information flow by allowing the flight data processing unit to receive ADS-B information directly from the surveillance data processing unit in addition to receiving system track information. This creates parallel information channels that enable full utilization of ADS-B data without fundamentally restructuring the centralized architecture.
Solution Approach 2:
The surveillance data processing unit acts as an intermediary that provides both processed system track information and raw ADS-B information to the flight data processing unit. This intermediary role enables the flight data processing unit to access multiple information sources while maintaining the existing system structure.
2Productivity
If the system waits for surveillance data processing to complete before coupling flight plan and flight path, then data processing follows a sequential workflow, but coupling efficiency and arrival scheduling are delayed
Solution Approach 1:
The flight data processing unit performs coupling operations in advance by receiving and processing ADS-B information before the surveillance data processing unit completes its full processing cycle. This preliminary action enables earlier coupling of flight plan and flight path, improving overall system productivity.
Solution Approach 2:
The system maintains continuous coupling operations by using ADS-B information that flows continuously from the surveillance data processing unit, rather than waiting for discrete processed outputs. This continuous information stream enables uninterrupted coupling operations and reduces scheduling delays.
3Reliability
If the system relies on radar information and fused system track for coupling, then data accuracy is maintained through sensor fusion, but coupling coverage is reduced when radar or surveillance processing is unavailable
Solution Approach 1:
The flight data processing unit is designed to handle multiple information sources universally - it can process both system track information from radar fusion and raw ADS-B information independently. This multi-functionality ensures coupling operations can continue using ADS-B data when radar or surveillance processing is unavailable.
Solution Approach 2:
The system prepares for potential surveillance processing failures by having the flight data processing unit ready to use ADS-B information directly. This prior preparation ensures coupling continuity even when the primary surveillance processing path is disrupted.
