Aircraft Alarm Documentation Access System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft pilots face difficulties in accessing and navigating through extensive operational documentation during flight, particularly when multiple alarms are generated, requiring them to manually search through various manuals to understand the impact of failures on aircraft performance, which can lead to oversight and increased workload.
Innovation Solution
A computer method and system that receives alarm indications from the aircraft's avionics and displays relevant documentation links, allowing pilots to access specific information quickly and contextually, eliminating the need to know the structure of the documentation and facilitating better decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pilots manually search through various manuals to understand alarm impacts, then comprehensive information can be found, but the workload increases and response time decreases
Solution Approach 1:
The system pre-establishes links between alarm indications and relevant documentation sections. When an alarm occurs, the corresponding documentation is automatically identified and made available, eliminating the need for pilots to manually search through manuals during critical situations.
Solution Approach 2:
The patent introduces an intermediary system (the display device and processing system) that acts as a bridge between the alarm system and the extensive operational documentation. This intermediary automatically retrieves and presents relevant information, reducing the cognitive load and time required for pilots to access necessary documentation.
2Loss of information
If extensive operational documentation is provided, then complete information is available, but navigation and access become difficult
Solution Approach 1:
The system extracts only the specific documentation sections relevant to the current alarm condition and presents them to the pilot. Instead of requiring navigation through entire manuals, the system isolates and displays only the pertinent information, making access straightforward and efficient.
Solution Approach 2:
The patent replaces the mechanical navigation process (physically flipping through pages or manually searching electronic catalogs) with an automated information retrieval system. The system automatically identifies and presents the required documentation based on alarm codes, substituting manual search mechanisms with automated processing.
3Reliability
If pilots consult multiple manuals during flight, then thorough analysis is possible, but workload and complexity increase
Solution Approach 1:
The system merges information from multiple documentation sources (FCOM, QRH, MEL, CDL) into a single integrated display. By consolidating relevant information from different manuals into one unified interface, the system maintains thorough analysis capabilities while reducing the complexity of managing multiple separate documents.
4Measurement precision
If detailed documentation structure is required for access, then information can be precisely located, but pilot knowledge requirements increase
Solution Approach 1:
The system performs the search and retrieval function autonomously without requiring pilot expertise in documentation structure. The processing system automatically matches alarm indications with relevant documentation sections, making the information retrieval process self-service and eliminating the need for pilots to know the detailed structure of operational manuals.
Data Source
AI summary
A method and a device for accessing the documentation of an aircraft according to alarms generated therein, where the documentation includes at least one document that is modifiable independently of the manufacturer of the aircraft. After having received at least one indication relating to at least one alarm generated by the avionics of the aircraft, at least one datum relating to the at least one alarm, including a link to at least one element of the documentation, is extracted and displayed.
