Flight Display System for Concurrent VSD and ND Data Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight display systems require users to navigate through multiple modes and window sizes to analyze specific sections of a flight plan, leading to increased head-down time and cognitive demand, as they often lack efficient display of multiple flight data parameters on vertical and lateral displays.
Innovation Solution
A flight display system that allows users to select a section of a flight plan on either the vertical situation display (VSD) or lateral navigation display (ND), visually distinguishing and labeling the section on both, and generating a flight parameters window with alphanumeric values and graphical representations of rate changes, while continuously updating with current aircraft status data.

Engineering Contradiction Analysis
1Loss of information
If users navigate through multiple modes and window range sizes to analyze specific sections of flight plan, then they can access detailed flight data, but head down time and cognitive demand increase
Solution Approach 1:
The flight parameters are segmented into different categories (vertical parameters on VSD, lateral parameters on ND) and displayed in organized groups. The selected section is further segmented with start and end points clearly marked, allowing users to quickly locate specific data without navigating through entire flight plans.
Solution Approach 2:
A flight parameters window is introduced as an intermediary element that consolidates and displays multiple flight data parameters in one location. This window acts as a mediator between the complex flight plan data and the user, presenting information in an easily digestible format without requiring users to switch between multiple display modes.
2Loss of information
If users navigate through multiple modes and window range sizes to analyze specific sections of flight plan, then they can access detailed flight data, but cognitive demand increases
Solution Approach 1:
Multiple flight data parameters are merged into a single flight parameters window that displays all relevant information simultaneously. Vertical parameters are combined on the VSD while lateral parameters are combined on the ND, reducing the cognitive load of switching between different data sources and modes.
Solution Approach 2:
The display system applies local quality by providing detailed flight parameter information specifically for the selected section of the flight plan, while maintaining context of the entire flight plan. The start and end points of the selected section are visually distinguished, allowing users to focus cognitive resources on the specific area of interest without being overwhelmed by the complete flight plan.
3Productivity
If multiple flight data parameters are displayed for selected section, then analysis capability is improved, but display complexity increases
Solution Approach 1:
The system utilizes two different display dimensions (VSD for vertical parameters, ND for lateral parameters) to organize flight data. This dimensional separation allows multiple parameters to be displayed simultaneously without creating visual clutter on a single display, maintaining simplicity while providing comprehensive analysis capability.

AI summary
Methods and systems for a flight display system are provided. The method includes: commanding a vertical situation display (VSD) and a lateral navigation display (ND) to render, concurrently, a viewing segment of a flight plan. The method includes receiving a user input selecting a section of the viewing segment, the user input being received on only one of the VSD and the ND. The method continues by commanding, concurrently, the VSD and the ND to visually distinguish the section, and to demark the section on the VSD with starting points and ending points. The method identifies a flight parameter, and for the flight parameter, includes (a) determining which display, among the VSD and the ND, is appropriate for the rendering of flight parameter information; (b) generating flight parameter information based on (a); and (c) overlaying the flight parameter information on the appropriate display.
