Runway Status Alert System for Closed Runway Incursion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Runway incursions occur due to misleading information provided to pilots when approaching or landing on closed runways, leading to safety concerns and significant financial losses.
Innovation Solution
An apparatus and method that generate and annunciate clear, non-misleading alerts to flight crews regarding the status of runways, using a runway database to provide timely positional advisories during taxi, takeoff, and landing operations, ensuring accurate situational awareness by distinguishing between open and closed runway conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional runway alert systems provide basic positional information only, then the system complexity remains low, but the information provided to pilots becomes misleading and insufficient for safe operations on closed runways
Solution Approach 1:
The system performs preliminary actions by pre-configuring the alert messages with closed runway status information in the database before the aircraft approaches. When the aircraft enters the alert zone, the system retrieves and delivers the pre-prepared informative message about the closed runway status, eliminating the need for complex real-time decision-making during critical flight phases.
Solution Approach 2:
The system introduces an intermediary layer by implementing a dedicated alert generation and delivery subsystem that sits between the aircraft's navigation system and the pilot. This intermediary component automatically processes runway status information and delivers customized alerts, reducing the cognitive load on the pilot and preventing information loss without requiring complex manual procedures.
2Reliability
If the system provides detailed closed runway status information, then pilot situational awareness and decision-making improve, but the information delivery system becomes more complex
Solution Approach 1:
The system implements self-service by automatically retrieving and delivering the appropriate closed runway status information based on the aircraft's position and the pre-configured database. The alert system autonomously determines which information to provide without requiring pilot input or complex manual configuration, thereby improving reliability while keeping the operational complexity low.
Solution Approach 2:
The system changes the parameter of information delivery by transitioning from generic positional alerts to specific, context-aware messages that include closed runway status. The alert message content dynamically adjusts based on the aircraft's proximity to closed runways, providing detailed information only when necessary and maintaining simplicity in normal operations.
3Loss of information
If traditional alert systems use generic messages like 'Approaching Taxiway', then the system remains simple to operate, but the information is misleading and causes runway incursions
Solution Approach 1:
The system applies local quality by customizing the alert message content specifically for each situation. Instead of using a generic alert for all runway approaches, the system delivers localized information tailored to the specific runway being approached and its operational status. When a closed runway is detected, the alert specifically mentions the closure, providing precise information that improves pilot understanding and prevents incursions.
Solution Approach 2:
The system inverts the traditional approach by not just providing basic positional information but actively highlighting the abnormal or critical status (closed runway) in the alert message. This inversion of the information delivery approach ensures that the most important safety-critical information is prominently displayed, making it impossible for pilots to miss the closure status while maintaining ease of operation through automated message delivery.
