Aircraft Message Sequence Management for Pilot Cognitive Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face a significant cognitive burden in finding specific messages among a large collection of text messages exchanged with a ground station, which can decrease flight safety due to the lack of an efficient message management system.
Innovation Solution
A method for managing messages between a ground station and an aircraft that involves acquiring and identifying messages, comparing their identifiers with a table of current sequences, and either associating them with existing sequences or generating new ones, allowing for easier retrieval and display of relevant messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text messages are stored in a logbook data link for later consultation, then messages are preserved for reference, but the pilot cannot easily find specific messages among the large collection of stored messages
Solution Approach 1:
The patent segments the large collection of stored messages into structured sequences grouped by operational subject (e.g., take-off phase, landing phase, cruising phase). Each sequence contains messages related to a specific flight phase or operational context, allowing pilots to navigate to relevant message groups rather than searching through all messages individually. This segmentation resolves the contradiction by making the stored message collection systematically accessible.
Solution Approach 2:
The patent introduces a new organizational dimension beyond simple chronological storage by adding operational subject classification. Messages are indexed not only by time but also by operational context (flight phases, operational subjects), creating a multi-dimensional retrieval system. This allows pilots to access messages based on operational context rather than having to search through the entire chronological log, thereby improving ease of operation while maintaining reliable storage.
2Loss of information
If all exchanged messages are displayed to the pilot, then complete information is available, but the cognitive burden increases and flight safety decreases
Solution Approach 1:
The patent extracts and highlights only the most relevant messages from the complete collection by organizing them into sequences based on operational subject. Instead of presenting all messages equally, the system extracts key messages related to current operational phases and presents them in a structured manner. This reduces the cognitive burden on pilots by filtering out less relevant information while maintaining access to complete information when needed, thereby preserving flight safety.
Solution Approach 2:
The patent applies local quality by providing different levels of information presentation based on operational context. Critical messages related to current flight phases are prominently displayed with enhanced visibility, while less critical messages are organized in accessible but less prominent positions. This differentiated presentation ensures that pilots focus on essential information for current operational needs while maintaining access to the complete message set, thus balancing information completeness with cognitive load management.
Data Source
AI summary
This method for managing messages exchanged between a ground station and an aircraft is implemented by an electronic device. Each message includes an identifier, a dialogue number and data. This method comprises acquiring a message, determining the identifier of the acquired message, and comparing the determined identifier with identifiers contained in a table of current sequences. When the identifier corresponds to a sequence of said table, the method comprises associating the acquired message with said sequence, and otherwise, it comprises generating a new sequence using a list of sequences, associating the acquired message with the new generated sequence, and updating the table of current sequences with the new generated sequence. Each sequence includes one or several dialogues, each dialogue including at least two messages.
