Phase-Specific Electronic Checklist Presentation for Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic checklist systems do not effectively restrict flight crews from completing critical tasks outside their designated phase of flight, potentially leading to overlooked tasks during high-stress situations, as they allow access and completion of checklist procedures irrespective of the flight phase.
Innovation Solution
An aircraft onboard system detects the current phase of flight, identifies critical tasks associated with that phase from an electronic checklist database, and presents these tasks via a display device to ensure timely completion, using a processor and memory element to manage and transmit critical task data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic checklist system allows flight crews to access and complete checklist procedures irrespective of the phase of flight, then the flight crew can complete tasks flexibly and quickly, but critical tasks may be overlooked or completed outside the appropriate phase of flight
Solution Approach 1:
The electronic checklist system dynamically adapts its behavior based on the detected phase of flight. The system transitions from a static checklist approach to a dynamic one where the phase of flight detection module continuously monitors flight conditions and adjusts the checklist presentation accordingly, highlighting only phase-relevant critical tasks.
Solution Approach 2:
The system implements feedback by detecting the current phase of flight and using this information to control which checklist items are presented and highlighted. The phase detection feedback loop ensures that the checklist display is continuously updated to reflect the current flight phase, preventing crews from completing tasks in inappropriate phases.
2Loss of information
If the electronic checklist system presents all checklist items regardless of phase of flight, then the flight crew has access to complete information, but the workload increases and critical tasks may be overlooked during high stress situations
Solution Approach 1:
The system extracts and isolates only the critical tasks relevant to the current phase of flight from the complete checklist database. By separating phase-specific critical tasks from the full checklist, the system presents a simplified view that reduces cognitive load while maintaining access to complete information when needed.
Solution Approach 2:
The checklist presentation is customized with local quality by applying different visual characteristics (such as highlighting, bolding, or positioning) specifically to the critical tasks relevant to the current phase. This selective emphasis allows the system to maintain information completeness while guiding attention to the most important tasks.
3Productivity
If the electronic checklist system allows completion of tasks outside the designated phase of flight, then the flight crew can complete tasks efficiently, but operational safety is compromised
Solution Approach 1:
The system takes preliminary anti-action by preventing the completion of checklist tasks that are not appropriate for the current phase of flight. The phase detection system proactively identifies and blocks inappropriate task completions before they can occur, rather than relying on post-completion verification.
Data Source
AI summary
A method for providing electronic checklist data onboard an aircraft is provided. The method detects, by an aircraft onboard system, a current phase of flight for the aircraft; obtains electronic checklist data by at least one processor onboard the aircraft; identifies, by the at least one processor, critical items associated with the current phase of flight, wherein the electronic checklist data comprises the critical items; and presents the critical items via aircraft display.
