Dynamic Alert Level Assignment for Aircraft Operational Phases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft alert systems display alerts in the order they are generated, ignoring the varying levels of urgency, which can overwhelm crew members and require them to manually prioritize alerts, rather than using contextual operational phases to dynamically assign alert levels based on the vehicle's operational phase.
Innovation Solution
A system that detects alert events and assigns alert levels dynamically based on the current and future operational phases of the vehicle, reducing immediacy for alerts with operational impacts in future phases and prioritizing alerts based on their operational impact during the current phase, using a contextualization approach to adjust alert levels and display them in a graphical user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If alerts are displayed in the order they are generated, then all alerts are presented to the crew, but the crew workload increases and response efficiency decreases due to lack of prioritization
Solution Approach 1:
The alert level assignment is made dynamic by evaluating the current operational phase of the vehicle and the operational phases impacted by each alert event. The system dynamically adjusts alert levels based on contextual information about which operational phases are current versus future phases, allowing the alert prioritization to adapt to the vehicle's operational context rather than using fixed priority rules
Solution Approach 2:
The system changes the parameter of alert level assignment from static (fixed in database) to dynamic (adjusted based on operational phase context). By modifying the alert level parameter according to whether the impacted operational phase is current or future, the system optimizes crew response efficiency while reducing unnecessary workload from low-priority alerts
2Adaptability or versatility
If the static database outputs the same alert information regardless of when the alert occurs, then consistency is maintained, but the system lacks adaptability to different operational contexts
Solution Approach 1:
The system performs preliminary evaluation of alert events by identifying which operational phases are impacted and comparing them to the current operational phase before displaying alerts to the crew. This preliminary contextual analysis allows the system to prepare appropriately prioritized alert information in advance, adapting to operational context while maintaining consistent alert generation
Solution Approach 2:
The alert level parameter is changed based on operational context - alerts impacting future operational phases are assigned lower levels while alerts impacting current phases receive higher priority. This parameter adaptation maintains information consistency while adding contextual relevance to alert displays
3Ease of operation
If all alerts are displayed with the same alert level, then simplicity is maintained, but the system cannot effectively prioritize alerts based on operational impact
Solution Approach 1:
The alert level assignment system uses dynamic evaluation based on operational phase context rather than static fixed levels. The system automatically adjusts alert levels by comparing impacted operational phases with the current operational phase, providing effective prioritization through contextual awareness rather than complex manual configuration
Solution Approach 2:
The system performs self-service by automatically evaluating and assigning appropriate alert levels based on operational phase information without requiring external input or complex configuration. The contextualization process autonomously determines priority levels by comparing alert-impacted phases with current operational phase

AI summary
The present disclosure provides detecting an alert event in a vehicle by monitoring an output of a sensor in the vehicle, identifying a first operational phase of the vehicle that is operationally impacted by the alert event, identifying a current operational phase of the vehicle, and in response to determining that the first operational phase is a future operational phase relative to the current operational phase of the vehicle, assigning a lower alert level to the alert event, and outputting, for display in a graphical user interface (GUI), the alert event with the lower alert level.
