NOTAM Readability via Text Segmentation and Emphasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NOTAMs are difficult for humans to read due to their high concentration of abbreviations, leading to potential safety hazards and increased pilot workload, especially in single-pilot operations where attention is already scarce.
Innovation Solution
A system and method that converts abbreviated terms into expanded terms, applies capitalization rules, and emphasizes words to enhance readability, filtering out irrelevant NOTAMs and displaying the most relevant ones via a display or printer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If NOTAMs use abbreviated terms to convey information efficiently, then information density is improved, but readability and understandability deteriorate
Solution Approach 1:
The patent segments the NOTAM text into individual words and applies different formatting styles to different segments based on their importance. Critical information such as hazard types, time periods, and location identifiers are capitalized or emphasized, while less critical abbreviated terms remain in lowercase. This segmentation allows the system to maintain high information density while improving readability through selective emphasis.
Solution Approach 2:
The patent applies local quality by varying the visual properties of different parts of the NOTAM text. Specific words are capitalized, bolded, or underlined based on their semantic importance and relevance to flight safety. This creates a hierarchy of visual prominence that guides pilot attention to critical information without requiring expansion of all abbreviated terms.
2Loss of information
If all NOTAMs are displayed to ensure complete information, then information completeness is improved, but pilot workload and attention requirements increase
Solution Approach 1:
The patent extracts and highlights only the most critical information elements from the full NOTAM text. By identifying and emphasizing key parameters such as hazard types, time periods, location identifiers, and regulatory references, the system allows pilots to quickly grasp essential information without processing every word of every NOTAM. Less critical information remains available but visually de-emphasized.
Solution Approach 2:
The patent applies partial action by selectively emphasizing only the portion of NOTAM text that is most relevant to flight safety and operations. Rather than requiring pilots to read and process 100% of the information equally, the system highlights approximately the top 20-30% of critical information that warrants immediate attention, while the remaining information is available for reference if needed.
3Reliability
If pilots spend more time reading NOTAMs to ensure safety, then safety is improved, but time available for other critical tasks decreases
Solution Approach 1:
The patent applies preliminary action by pre-processing and formatting NOTAM information before presentation to the pilot. The system pre-identifies critical information elements, applies appropriate capitalization and emphasis, and organizes the content in a visually hierarchical manner during the NOTAM generation process. This preliminary formatting reduces the cognitive load and reading time required when pilots review the information during pre-flight or in-flight operations.

AI summary
A system and method for generating an enhanced set of NOTAMs. The system and method include converting one or more abbreviated terms of a NOTAM text of the NOTAM into one or more respective expanded terms. The system and method include applying a set of capitalization rules to the NOTAM text. The system and method include emphasizing a portion of each word of the NOTAM text based on one or more emphasizing rules, where words are terms with only letters. The system and method include directing at least a portion of the enhanced set of NOTAMs to be at least one of displayed via a display or physically printed by a printer.
