Cockpit Alert Display by Crew Role to Reduce Pilot Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cockpit display systems in aircraft fail to differentiate between crew members' roles, leading to unnecessary distractions and potential misinterpretation of non-critical alerts, which can disrupt the pilot flying during critical flight phases.
Innovation Solution
A display device with dedicated display areas for each crew member, featuring a display management assembly that tailors alert indications and auditory/haptic alerts based on the crew member's role, ensuring appropriate awareness and response levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same alert indication is displayed for both pilot flying and pilot non-flying, then redundancy and consistency are maintained, but unnecessary distractions and disruptions occur for the pilot flying during critical flight phases
Solution Approach 1:
The patent applies local quality by differentiating alert display characteristics based on the specific crew member's role. The pilot flying receives alert indications with different visual characteristics (e.g., color, intensity, duration) compared to the pilot non-flying, allowing each role to receive appropriately tailored information without disrupting the other's primary functions
Solution Approach 2:
The alert indication system is segmented into role-specific display modes. The display management assembly divides the alert presentation into distinct channels: one optimized for the pilot flying's needs during critical phases, and another for the pilot non-flying's monitoring role, thereby resolving the contradiction between consistency and distraction
2Loss of information
If alert indications are displayed with high visibility to ensure crew awareness, then alert detection is improved, but the pilot flying's focus on critical flight operations is disrupted
Solution Approach 1:
The patent changes display parameters (color, brightness, duration, position) of alert indications based on the detected role of the crew member. The display management assembly adjusts these parameters dynamically to provide sufficient alert awareness for the pilot non-flying while minimizing visual distraction for the pilot flying during approach and landing phases
3Loss of information
If the system provides comprehensive alert information to all crew members, then information completeness is maintained, but the complexity of the display system increases
Solution Approach 1:
The display management assembly dynamically adapts alert display characteristics based on real-time detection of crew member roles. This dynamic adjustment allows the system to maintain information completeness for both crew members while simplifying the effective display complexity by presenting role-appropriate information formats rather than identical comprehensive displays to both

AI summary
A device including a display management system, configured to display on at least one of a first dedicated display area and a second dedicated display area, an alert indication corresponding to alert information received from an avionics central unit. It is configured to receive role information of the crew member present respectively on a first seat located in front of the first dedicated display area and on a second seat located in front of the second dedicated display area. The display management system is configured to display an alert indication corresponding to the received alert information, on at least one of the first dedicated display area and the second dedicated display area, defined based on the role information of the crew member present respectively in front of the first dedicated display area and the second dedicated display area.
