Inbound Traffic Alert for Runway Incursion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic management systems face challenges in preventing runway incursions due to limitations in radar coverage, adverse weather conditions, and reliance on human observation and communication.
Innovation Solution
A method is provided for generating an inbound traffic alert by receiving location data from an aircraft's onboard sensor and target traffic, determining the aircraft's and target traffic's location, speed, and direction, and outputting an alert when the aircraft is on a runway and the target traffic meets specific alert criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If radar systems are used to monitor aircraft movements, then coverage area is increased, but blind spots and reliability issues remain in certain conditions
Solution Approach 1:
The patent introduces an intermediary system that combines multiple data sources (location sensors on aircraft, radar, visual observation) through a communication network. This intermediary layer integrates diverse monitoring capabilities to compensate for individual system limitations, particularly radar blind spots, thereby improving overall reliability of runway incursion prevention while maintaining broad coverage.
2Device complexity
If human observation and communication are relied upon for traffic monitoring, then system complexity is reduced, but accuracy and reliability deteriorate
Solution Approach 1:
The patent implements self-service through automated location sensors on aircraft that continuously transmit position data without human intervention. The system automatically processes this data, compares it with runway geometry, and generates alerts autonomously. This automation maintains measurement precision while keeping the overall system relatively simple, as the sensors and processing logic are integrated directly into the aircraft and ground station infrastructure.
3Reliability
If multiple data sources are integrated for comprehensive monitoring, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional integrated system where a single ground station receives and processes multiple data types (radar returns, location sensor data, visual observation) through unified algorithms. The same processing infrastructure handles different data sources and alert criteria, reducing the need for separate specialized systems. This multi-functional approach improves reliability through comprehensive monitoring while controlling complexity by using a single integrated platform rather than multiple independent systems.
Data Source
AI summary
A method for providing an inbound traffic alert comprises receiving location sensor data for the aircraft. Location data is also received for target traffic. Based on the location sensor data for the aircraft, a location, a speed, and a direction of travel are determined for the aircraft. A location, a speed, and a direction of travel are determined for the target traffic based on the location data for the target traffic. The method further comprises determining that the aircraft is on a runway, and determining that the aircraft is an ownship. The method further comprises determining that the target traffic meets one or more target traffic alert criteria. An inbound traffic alert is output based upon determining that the aircraft is on the runway, the aircraft is the ownship, and the target traffic meets the one or more target traffic alert criteria.
