Integrated Runway Alerting With Cross-System Priority Override
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ground proximity systems generate numerous alerts independently, which can obscure high-priority runway alerts, posing a risk to aircraft safety due to their self-contained nature within the aircraft.
Innovation Solution
An integrated runway safety system that combines airport traffic data, safety data, and aircraft parameters to generate prioritized alerts, overriding lower-priority alerts to ensure high-priority runway safety alerts are broadcasted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ground proximity systems generate multiple independent alerts, then comprehensive safety monitoring is achieved, but high-priority runway alerts become obscured among lower-priority alerts
Solution Approach 1:
The patent merges multiple independent alert systems into a unified alert management system that processes all alerts through a common priority evaluation framework. This integration ensures that runway safety alerts are evaluated against a standardized set of criteria and assigned appropriate priority levels, preventing them from being obscured by lower-priority alerts from other systems.
Solution Approach 2:
The system changes the parameter of alert prioritization by introducing dynamic priority assignment based on multiple factors including alert type, aircraft state, and environmental conditions. Runway safety alerts are assigned higher priority parameters that ensure they are communicated to pilots before other less critical alerts, directly addressing the information loss problem.
2Adaptability or versatility
If self-contained ground proximity systems are used within aircraft, then system independence is maintained, but alert prioritization across multiple systems becomes problematic
Solution Approach 1:
The patent implements a universal alert management system that can handle multiple types of alerts from different sources (ground proximity, terrain awareness, traffic collision avoidance, etc.) through a single integrated framework. This multi-functional approach allows the system to adapt to various alert types while maintaining consistent prioritization logic, reducing the complexity of managing multiple independent systems.
Solution Approach 2:
The system introduces an intermediary alert management layer that sits between individual sensor systems and the pilot interface. This mediator receives alerts from various independent systems, evaluates their priority based on predefined criteria, and sequences their presentation to the pilot, thereby simplifying the overall alert management complexity while maintaining system independence.
3Reliability
If multiple alerts are broadcast simultaneously to pilots, then comprehensive safety information is provided, but critical runway alerts may not receive adequate attention
Solution Approach 1:
The system performs preliminary prioritization and sequencing of alerts before presenting them to the pilot. By pre-evaluating alert importance and arranging them in a predetermined priority order, the system ensures that critical runway safety alerts are presented first, making it easier for pilots to process information without being overwhelmed by simultaneous alerts of varying importance.
Solution Approach 2:
The patent applies different presentation qualities to different alert types based on their priority. Critical runway safety alerts receive enhanced presentation characteristics (such as distinct audio warnings, prominent visual displays) compared to lower-priority alerts, ensuring they receive adequate pilot attention while still providing comprehensive safety information through the full alert suite.
Data Source
AI summary
An integrated runway safety system installed on an aerial vehicle is configured to analyze airport traffic data, airport safety data, and one or more parameters of the aerial vehicle in a combined context of runway geometry of a runway selected by the aerial vehicle. The integrated runway safety system can generate alerts, as well as prioritize and override alerts generated from other systems when the aerial vehicle is approaching or on a runway. The alerts processed by the integrated runway safety system are broadcasted to personnel onboard the aerial vehicle based on the priority associated with the alert.
