Aircraft Cockpit Interaction Checks for Unvalidated Avionics Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In aircraft cockpits, inadvertent modifications to critical avionics system settings can occur due to system failures, leading to hazardous or catastrophic consequences if not detected and addressed.
Innovation Solution
An interaction system in the cockpit that includes a setting medium for generating setting and validation signals, a display module for displaying selected settings and generating feedback signals, and a processing module to detect modifications and verify their validation, thereby alerting the operator to any inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a setting value is modified without validation, then the system responds quickly to operator input, but the risk of inadvertent modification increases
Solution Approach 1:
The system performs preliminary validation checking by comparing the current setting value with the previously displayed value before allowing the modification to take effect. This preliminary action prevents inadvertent modifications while maintaining quick response to valid operator inputs.
Solution Approach 2:
The system implements feedback by displaying the setting value and monitoring for consistency between the displayed value and the setting medium value. This feedback mechanism detects inadvertent modifications and alerts the operator, ensuring reliability while maintaining operational speed.
2Device complexity
If simple display changes are used to indicate modification, then the system remains simple, but the operator may miss the alert
Solution Approach 1:
The system uses visual changes in the display module to indicate when a setting value has been modified. By changing the appearance of the displayed value, the system draws the operator's attention to the modification without adding complex alert mechanisms.
Solution Approach 2:
The system performs preliminary detection of modification consistency between the setting medium and display module, then alerts the operator when inconsistency is detected. This ensures that modifications are noticed while keeping the system relatively simple.
3Reliability
If validation is required for each setting change, then inadvertent modifications are prevented, but the operation time increases
Solution Approach 1:
The system performs automatic self-validation by comparing the setting value from the setting medium with the displayed value. This self-service validation prevents inadvertent modifications without requiring additional manual validation steps from the operator, thus minimizing operation time.
Solution Approach 2:
The system implements continuous feedback monitoring that automatically detects inconsistencies between setting and display values. This automated feedback mechanism ensures reliability without adding manual validation steps, maintaining efficient operation.

AI summary
An interaction system in the cockpit of an aircraft for controlling at least one avionics system with setting values, including a setting medium configured to generate a setting signal corresponding to a setting value selected by an operator following a first action, and a validation signal corresponding to a validation of the selected setting value following a second action, a display module configured to display the selected setting value and to generate a feedback signal including a graphic signature of the displayed setting value, and a processing module configured to receive each feedback signal and each validation signal, to detect each modification in the setting value and to verify that each detected modification corresponds to a validation signal.
