Aircraft Message Management System for Pilot Cognitive Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current message management systems for aircraft pilots lack an efficient way to quickly overview and retrieve relevant text messages exchanged with ground stations, leading to increased cognitive load and decreased flight safety due to the inability to quickly find necessary messages among stored communications.
Innovation Solution
A method and device that organize and display text messages by type and timeline, allowing pilots to associate messages with dialogues and sequences, using symbols on a display zone with axes representing time and message type, enabling quicker access and filtering of messages based on contextual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If text messages are stored in the storage capability for later consultation, then message retrieval capability is improved, but the cognitive load on the pilot increases and flight safety decreases due to inability to quickly find necessary messages
Solution Approach 1:
The patent segments messages into different types (ATC and AOC) and organizes them into dialogues and sequences based on operational subjects. This segmentation allows pilots to quickly locate relevant messages by filtering through organized categories rather than searching through all stored messages, reducing both retrieval time and cognitive load while maintaining flight safety.
Solution Approach 2:
The patent introduces a visual display dimension that organizes messages along temporal axes and by message type. This dimensional organization provides a synthetic overview that enables rapid identification of relevant messages without requiring pilots to mentally process all stored communications, thus improving retrieval speed and maintaining safety.
2Loss of information
If all text messages are displayed and stored for comprehensive access, then message completeness is improved, but the pilot's cognitive load increases and the ability to quickly find necessary messages deteriorates
Solution Approach 1:
The patent divides messages into segments based on type (ATC/AOC) and operational subject, creating an organized structure that maintains completeness while improving search efficiency. Pilots can access any message through the organized hierarchy without being overwhelmed by the entire message log.
Solution Approach 2:
The patent introduces an intermediary display layer that provides a synthetic overview of messages organized by type and time. This intermediary structure acts as a mediator between the complete message storage and the pilot's information needs, enabling efficient retrieval without sacrificing completeness.
Data Source
AI summary
A method and electronic device for control of messages exchanged between an aircraft and a ground station, and associated computer program product are disclosed. In one aspect, the method includes acquiring a message, extracting descriptive data from the acquired message, and determining the identifier of the acquired message. If the identifier of the acquired message corresponds to a shared identifier of the messages of a dialog in progress, the method includes associating that acquired message with that dialog. If not, the method includes associating the acquired message with a new dialog. The method further includes determining the position of a symbol corresponding to the dialog associated with the acquired message, the position being determined based on the type and start date of this dialog, the symbol being configured to be displayed in a display zone of the symbols corresponding to the different dialogs.
