Modular Aircraft Warning Task Sequencer Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing onboard flight warning management systems are complex and costly to develop and maintain due to their monolithic sequential code structure, making it difficult to adapt to changing airline configurations and regulatory requirements.
Innovation Solution
A modular warning management system structured as a task sequencer with a common system core, allowing easy replacement of modules and using a parameterizable configuration table for scheduling tasks and procedures, including XML file conversion for generating the configuration table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a monolithic sequential code structure is used for the warning management system, then the system can be developed and certified as a unified whole, but the development and maintenance complexity increases significantly and adaptability to changing configurations becomes difficult
Solution Approach 1:
The patent divides the warning management system into independent functional modules (failure detection module, warning module, user interface module, task sequencer) that can be developed, tested, and maintained separately. Each module has a well-defined interface with others, allowing modular replacement and adaptation without affecting the entire system, thus reducing development and maintenance complexity while maintaining certification reliability.
2Reliability
If a monolithic sequential code structure is used, then the system provides a unified warning management function, but the adaptability to different airline configurations and regulatory requirements becomes limited
Solution Approach 1:
The patent introduces a parameterizable configuration table that allows dynamic adaptation of the system to different airline configurations and regulatory requirements. The configuration table can be modified through operation maintenance procedures without changing the core system architecture, enabling the system to adapt to changing requirements while maintaining its unified warning management function.
Solution Approach 2:
The task sequencer module serves multiple functions: it schedules tasks, manages priorities, handles procedure execution, and provides adaptability through configuration tables. This multi-functional design allows a single modular component to handle various airline-specific requirements without requiring separate specialized systems for each configuration.
3Adaptability or versatility
If the configuration is modified through operation maintenance procedures, then the system can be adapted to changing requirements, but the time required for maintenance operations increases
Solution Approach 1:
The system pre-defines the structure and parameters of the configuration table during development, including the format for storing airline-specific settings and the interfaces for loading configurations. This preliminary structuring allows maintenance personnel to quickly load new configurations without needing to reconfigure the entire system, reducing maintenance operation time while preserving adaptability.

AI summary
The invention relates to onboard failure warning management systems on aircraft, or flight warning systems (FWS). Traditionally, the logic of these systems refers to procedures to be executed by the crew in response to warnings. Modifications, however minor, to the procedures involve a new development that can be installed on the airplane computer only as part of a costly maintenance procedure, given notably the need to carry out exhaustive tests on the application. The invention introduces the concept of tasks defined by a set of variables, notably the warning and the procedure in which the task is executed, its category, its priority level and its status. Thus, the computer programs can be organized in modules that call the tasks to be executed, the parameters of said tasks being defined in a configuration table that can be updated as the procedures change during simple operation maintenance procedures.
