Context-Aware NOTAM Filtering for Flight Plan Relevance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft pilots face the challenge of manually sifting through numerous Notices to Air Missions (NOTAMs) to identify critical information, leading to potential misses of important notifications due to the lengthy and standardized format of these messages.
Innovation Solution
A system that filters and prioritizes NOTAMs based on relevance and criticality using a processor, display device, and communication device, converting standard abbreviations to plain language and generating alternate flight plans when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots manually review all NOTAMs to ensure critical information is not missed, then completeness of information review is improved, but time consumption and workload increase significantly
Solution Approach 1:
The patent introduces an automated NOTAM processing system that acts as an intermediary between NOTAM broadcast and pilot review. The system receives NOTAMs, filters them based on flight plan relevance, assigns criticality scores, and presents only essential information to pilots. This intermediary processing resolves the contradiction by ensuring comprehensive review through automation while reducing pilot time investment.
Solution Approach 2:
The system performs preliminary filtering and criticality assessment of NOTAMs before presenting them to pilots. By pre-processing the information and identifying critical items in advance, the system ensures that all potentially relevant NOTAMs are reviewed while minimizing the time pilots spend on this task.
2Measurement precision
If pilots manually analyze lengthy NOTAM lists to identify critical items, then thoroughness of analysis is improved, but potential for missing critical NOTAMs increases due to human error
Solution Approach 1:
The automated processing system serves as an intermediary that eliminates human error in NOTAM analysis. The system applies consistent filtering criteria and criticality scoring algorithms to all NOTAMs, ensuring thorough and reliable identification of critical information without the variability and potential mistakes of manual review.
Solution Approach 2:
The system provides feedback to pilots by highlighting the criticality level of each NOTAM and explaining why certain NOTAMs are deemed critical. This feedback mechanism ensures thorough analysis while reducing the risk of missing critical information by guiding pilot attention to the most important items.
3Loss of information
If all NOTAMs are presented to pilots in standard abbreviated format, then information completeness is maintained, but ease of understanding and quick identification of critical items deteriorates
Solution Approach 1:
The system applies local quality by presenting different formats of NOTAM information based on their criticality and relevance. Critical NOTAMs are highlighted with enhanced formatting, summaries, and contextual information, while less important items maintain standard format. This resolves the contradiction by optimizing presentation quality for each specific NOTAM rather than using a uniform format.
Solution Approach 2:
The system segments NOTAMs into different categories based on criticality levels and presents them in organized groups. By dividing the information into priority-based segments, the system maintains complete information while making it easier for pilots to quickly identify and understand critical items through structured presentation.
4Productivity
If the system filters and prioritizes NOTAMs automatically, then time efficiency and ease of operation are improved, but device complexity increases
Solution Approach 1:
The NOTAM processing system is integrated into the existing flight management system, making it multi-functional. The same hardware platform performs both traditional flight management functions and automated NOTAM processing, reducing the need for separate complex systems while maintaining high productivity.
Solution Approach 2:
The system processes NOTAMs using pre-programmed algorithms and flight plan data already available in the system. By utilizing existing resources and automated processing, the system achieves high time efficiency without requiring proportionally increased complexity, as the processing leverages self-contained capabilities.

AI summary
A system for filtering and presenting notifications received by an aircraft includes a processor, a display device, a communication device, and computer-readable memory. The computer-readable memory encoded with instructions that, when executed by the processor, cause the system to perform the following steps. The system receives one or more broadcast notifications. The notifications are, for example, Notices to Air Missions (NOTAMs). The system filters the one or more broadcasted notifications based upon applicability to a present flight plan to generate applicable notifications. The system filters the applicable notifications based upon one or more filtering criteria to assign a criticality to each of the applicable notifications. The system display, via the display device, the applicable notifications based upon the criticality of each of the applicable notifications. The system outputs alternate flight plans due to restrictions on the present flight plan.
