Cockpit Display Briefing Panel for Instrument Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cockpit displays are inadequate for efficiently presenting instrument procedure information due to limited resolution and physical size, often cluttering essential navigational and flight management processes, making it cumbersome for pilots to navigate and maintain procedures, especially during critical low-visibility operations.
Innovation Solution
A method is implemented to display instrument procedure information on a cockpit display device by rendering a navigational map and overlaying a briefing panel with menu segments associated with specific procedure types, allowing pilots to select relevant information without obstructing situational awareness, using a flight management system that accesses a database containing procedure information for various airports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If printed charts are used to display instrument procedure information, then comprehensive procedure information can be displayed, but the pilot must locate and review multiple charts which is cumbersome and inconvenient
Solution Approach 1:
The patent creates an electronic copy of the printed instrument procedure charts and displays them on a cockpit display device. This electronic copy contains the same comprehensive procedure information as the printed charts but can be accessed, searched, and displayed interactively, eliminating the need for pilots to physically locate and review multiple printed charts.
Solution Approach 2:
The patent divides the instrument procedure information into different segments or categories (e.g., approach procedures, departure procedures, minimums, radio frequencies) and allows pilots to selectively access and display only the relevant segments through interactive controls, improving efficiency while maintaining comprehensive information availability.
2Ease of operation
If electronic display is used to show instrument procedure charts, then information can be accessed electronically, but the resolution and physical size limits prevent accurate reproduction of charts
Solution Approach 1:
The patent implements a dynamic display system where the electronic chart can be zoomed, panned, and adjusted in real-time based on the pilot's needs. The display adapts its resolution and scale dynamically, allowing high-detail viewing of specific chart areas while maintaining the ability to overview the entire procedure, thus overcoming fixed resolution limitations.
Solution Approach 2:
The patent adds interactive dimensionality to the electronic display by incorporating zooming and panning capabilities. This transforms the static 2D chart into an interactive multi-level display where pilots can access detailed information at any resolution level, effectively compensating for the physical size and resolution limitations of the display device.
3Loss of information
If instrument procedure chart is displayed on electronic display, then information is available electronically, but the display area is limited and other navigational displays must be compromised
Solution Approach 1:
The patent segments the display into different functional zones, allowing the instrument procedure chart to be displayed in a dedicated portion of the electronic display device. This segmentation enables procedure information to be accessed without requiring the entire display area, preserving space for other critical navigational displays while maintaining comprehensive procedure information availability.
Solution Approach 2:
The patent utilizes the temporal dimension by allowing the procedure chart to be displayed, hidden, or minimized based on the flight phase and pilot requirements. The chart can be quickly brought up when needed and concealed when not required, effectively adding a time dimension to the spatial display arrangement and allowing comprehensive information access without permanently occupying display space.

AI summary
Methods are provided for presenting procedure information for an airport on a display device onboard an aircraft. A method comprises displaying a map on a display device and displaying a briefing panel overlying a portion the map. The briefing panel includes a plurality of segments, wherein each segment is associated with a type of procedure information for the airport.
