Avionic Display NOTAM Chart Correlation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face increased cognitive workload due to the lack of a direct means to open charts referenced in Notices to Airmen (NOTAMs), requiring manual selection from a list of charts, which can be time-consuming and error-prone, especially for real-time safety-related updates.
Innovation Solution
A system and method that correlate NOTAMs with pre-loaded charts on an avionic display, using a flight management system, position determining system, and controller circuit to render selectable visual indicators, allowing seamless switching between NOTAM and chart pages, thereby establishing a two-way correlation for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots manually select charts from a list after reading NOTAMs, then they can access chart information, but their cognitive workload increases and the process becomes time-consuming
Solution Approach 1:
The system automatically correlates NOTAMs with relevant charts and presents them to the pilot, eliminating the need for manual chart selection. The controller circuit receives NOTAMs, identifies referenced charts, and displays them automatically, allowing the system to serve itself rather than requiring pilot intervention for chart lookup
Solution Approach 2:
The controller circuit acts as an intermediary between the NOTAM source and the chart database. It receives NOTAMs, parses chart references, queries the chart database, and presents correlated charts to the pilot, thereby mediating the interaction and eliminating manual searching
2Loss of time
If pilots manually browse through chart lists to find referenced charts, then they can access the needed information, but the process becomes error-prone and time-consuming
Solution Approach 1:
The system performs preliminary correlation between NOTAMs and charts before the pilot needs the information. The controller circuit proactively identifies and prepares relevant charts for display, so when the pilot views a NOTAM, the corresponding chart is already ready for immediate access, eliminating time-consuming manual browsing
Solution Approach 2:
The system provides feedback by automatically displaying correlated charts in response to NOTAM display. When a pilot views a NOTAM, the system detects this and automatically presents the referenced chart, creating a feedback loop that eliminates the need for manual chart location and reduces time loss
3Ease of operation
If the system displays both NOTAM and chart information simultaneously with direct correlation, then access time is reduced, but the display system complexity increases
Solution Approach 1:
The system segments the correlation function into distinct processing stages: receiving NOTAMs, parsing chart references, querying the chart database, and displaying results. This segmentation allows the controller circuit to handle complexity in manageable steps while providing simple direct access to pilots
Solution Approach 2:
The controller circuit performs multiple functions: it manages flight plan data, processes NOTAMs, queries the chart database, and controls display output. This multi-functionality consolidates complexity into a single universal controller rather than requiring separate systems for each function

AI summary
Systems and methods for correlating a Notice to Airman (NOTAM) with a chart displayed on an avionic display in a cockpit of an aircraft. The method includes receiving a flight plan (FP); receiving a position and location of the aircraft; and, rendering an avionic display comprising a chart page or a NOTAM page. Responsive to receiving a NOTAM, the method determines whether the NOTAM is relevant. The NOTAM is relevant when the NOTAM is concurrently related to the FP and references a chart of a plurality of pre-loaded charts onboard the aircraft. Responsive thereto, a selectable visual indicator of the chart is rendered on the NOTAM page of the avionic display. The NOTAM is also relevant when it is related to a chart page displayed on the avionic display; responsive thereto, a selectable visual indicator of the NOTAM is rendered on the chart page displayed on the avionic display.
