Integrated IFR Approach Chart Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instrument flight rules (IFR) approach charts are complex, requiring pilots to switch between plan and profile views, perform mental calculations, and sift through redundant information, which can lead to time-consuming reading and decreased focus on aircraft instruments, increasing the risk of loss of control.
Innovation Solution
A simplified chart design where the final approach path is aligned with the runway, with all necessary information presented in a single view, including altitude and distance markers, and color-coded frequencies, reducing the need for mental calculations and improving information accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing approach charts are used with two views (plan view and profile view), then comprehensive information is provided, but the pilot must switch between views and perform mental calculations, increasing time consumption and reducing safety
Solution Approach 1:
The patent merges the plan view and profile view into a single integrated chart view. The approach path is displayed as a vertical line with altitude markers on the left and distance markers on the right, combining lateral and vertical navigation information in one location. This eliminates the need for pilots to switch between separate views and reduces the time required to understand the approach procedure.
Solution Approach 2:
The patent segments the approach chart into distinct functional elements: the vertical approach path line, altitude markers on the left side, distance markers on the right side, and runway information at the bottom. This segmentation organizes information logically and allows pilots to quickly locate specific data without wading through a monolithic chart design.
2Adaptability or versatility
If existing charts are drawn north up, then standard navigation convention is maintained, but the chart does not provide a good picture of what the pilot will see on the approach
Solution Approach 1:
The patent inverts the traditional north-up chart orientation by aligning the approach path vertically with the runway at the bottom. This inversion makes the chart directly represent the pilot's visual perspective during the approach, where the runway appears at the bottom of the visual field and the approach path extends upward. This improves the chart's ability to depict what the pilot actually sees while remaining compatible with standard navigation practices.
3Loss of information
If information is written in many places on existing charts, then comprehensive data is available, but it becomes hard to find critical information when time is critical
Solution Approach 1:
The patent applies local quality by placing specific types of information in specific locations: altitude markers are concentrated on the left side of the approach path, distance markers are on the right side, and runway information is at the bottom. This localized organization allows pilots to quickly scan for the specific information they need without searching through scattered data points across the entire chart.
4Reliability
If the same information is written multiple times on existing charts, then redundancy provides backup, but it loads the chart with information requiring more time to read
Solution Approach 1:
The patent extracts redundant information by presenting each piece of critical data (altitude, distance, runway information) exactly once in its optimal location. Instead of repeating the same information multiple times across different views or sections, the design provides the necessary data a single time in a format that is immediately useful to the pilot during the approach.

AI summary
An instrument flight rules (IFR) approach chart for facilitating a pilot's approach and landing of an aircraft at an airport includes a straight vertical line representing a runway on which the aircraft is to land with the beginning of the runway closer to the bottom than the top of the map, a second straight line representing a final approach flight path vertically aligned with the runway line and extending downwardly from the bottom end of the runway line, third straight lines extending across and perpendicular to the second straight line, altitude numbers at the ends of the third lines on one side of the second line and distance to the runway number at the ends of the third line on a second side of the second line.
