Primary Flight Display Annunciation Checklist Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft instrumentation systems require crew members to manually search for checklists in response to primary flight display (PFD) annunciations, leading to increased workload and inefficiency due to the inability to interact directly with PFD annunciations on the primary flight display.
Innovation Solution
A system and method that includes a display device with a primary flight display area and processors to receive instrumentation parameters, display PFD annunciations, detect user selections, and retrieve corresponding checklists, allowing direct access to checklists from the PFD display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If crew members manually search for checklists in response to PFD annunciations, then checklists can be accessed, but crew workload increases and efficiency decreases
Solution Approach 1:
The patent extracts the checklist retrieval function from the manual search process by making checklists directly accessible through the PFD annunciation interface. When a crew member encounters an annunciation on the PFD, the corresponding checklist is automatically retrieved and displayed without requiring manual search through reference manuals or separate systems, thus eliminating the workload inefficiency while maintaining productivity
Solution Approach 2:
The system introduces an intermediary mechanism that links PFD annunciations directly to their corresponding checklists. This intermediary function automatically matches annunciations with checklists and presents them to the crew, eliminating the need for manual searching while ensuring the correct checklist is provided, thereby improving both efficiency and ease of operation
2Reliability
If PFD annunciations are displayed, then crew is alerted of malfunctions, but inability to directly access checklists creates unnecessary EICAS messages
Solution Approach 1:
The patent merges the malfunction alerting function with the checklist access function by integrating both capabilities into the PFD interface. When an annunciation is displayed to alert the crew of a malfunction, the corresponding checklist is simultaneously made accessible through the same interface, eliminating the need for separate EICAS messages and reducing system complexity while maintaining reliable malfunction notification
3Loss of information
If checklists are displayed in secondary displays or paper manuals, then checklists are available, but direct interaction with PFD annunciations is prevented
Solution Approach 1:
The patent applies universality by making the PFD interface multi-functional - it serves both as a flight display and as a direct access point for checklist retrieval. The PFD annunciations are made interactive, allowing crew members to directly access checklists through the same display device, eliminating the need for separate secondary displays or paper manuals while maintaining complete checklist availability and improving interface integration

AI summary
A system for providing dynamic primary flight display flags includes a display device, a user interface device, and a processor configured to: receive at least one instrumentation parameter, display one or more primary flight display annunciations in the primary flight display area of the display device in response to the received at least one instrumentation parameter, receive one or more signals from the user interface device indicative of a user selection of the displayed one or more primary flight display annunciations, retrieve one or more checklists corresponding to the one or more primary flight display annunciations, and display the one or more checklists corresponding to the one or more primary flight display annunciations in response to the received signal indicative of a user selection of the one or more primary flight display annunciations.
