Aircraft Type Recognition Using Historical Activity Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air traffic control systems struggle to differentiate between flight movements that pose a risk of collision and those that do not, leading to an information overload for air traffic controllers and increased collision risks due to the rising air traffic volume, including unmanned aircraft and those operating under visual flight rules.
Innovation Solution
An airspace surveillance method that identifies regions of increased activity for specific aircraft types using past surveillance data, visually distinguishing or hiding aircraft within these regions to simplify information display and reduce collision risks, employing geometric shapes like cylinders or corridors, and adjusting thresholds based on location-specific factors.

Engineering Contradiction Analysis
1Loss of information
If all flight movements are displayed in conventional air traffic control systems, then complete surveillance information is provided, but information overload occurs and collision risk increases
Solution Approach 1:
The surveillance information is segmented by aircraft type and operational characteristics. The system divides flight movements into distinct categories (manned aircraft, unmanned aircraft, model airplanes, visual flight rules aircraft) and applies different display rules to each segment, allowing controllers to focus on relevant information without being overwhelmed by all flight movements simultaneously.
Solution Approach 2:
Different display qualities are applied to different regions and aircraft types. High-risk areas such as controlled airspace near airports receive enhanced surveillance and display priority, while low-risk areas like model airfields use reduced display priority. This local differentiation optimizes information presentation based on actual collision risk levels.
2Reliability
If conventional systems display all flight movements, then comprehensive monitoring is achieved, but controller workload increases and collision detection accuracy decreases
Solution Approach 1:
The system performs preliminary classification and risk assessment of aircraft before they enter controlled airspace. By pre-identifying high-risk aircraft types and their intended operations, the system prepares surveillance data in advance, allowing controllers to immediately focus on relevant threats without needing to analyze all flight movements from scratch.
Solution Approach 2:
An automated classification system acts as an intermediary between raw surveillance data and controller display. This intermediary layer filters, categorizes, and prioritizes flight movement information based on aircraft type, operational rules, and airspace restrictions, presenting only the most relevant information to controllers in an organized manner.
3Productivity
If traditional surveillance methods are used, then all aircraft are monitored equally, but risk differentiation between aircraft types is lost
Solution Approach 1:
The system changes key parameters for different aircraft types including display priority, surveillance intensity, and risk threshold levels. Manned aircraft operating under instrument flight rules receive high-priority surveillance with low risk thresholds, while model airplanes at designated airfields receive low-priority surveillance with high risk thresholds, enabling precise risk assessment tailored to each aircraft category.
