Flight Deck Display Color-Coding Multi-Path Arrival Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-path arrival (MPA) procedures, air traffic controllers face challenges in maintaining procedural and situational awareness due to the complexity of different approach paths and aircraft assignments, which can lead to confusion and incorrect flight paths, especially when flight crews are conditioned to follow preceding aircraft without clear differentiation.
Innovation Solution
A system and method for displaying MPA procedures on an aircraft's display unit, where the assigned approach path is color-coded or augmented to differentiate it from other paths, enhancing procedural awareness and situational awareness by clearly indicating the assigned path and other aircraft's paths, thereby preventing incorrect follow-through and maintaining traffic separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flight crews follow preceding aircraft to maintain situational awareness, then ease of operation is improved, but reliability deteriorates due to confusion when multiple different approach paths are assigned
Solution Approach 1:
The patent applies color-coding to different approach paths on the navigation display. Each predefined approach path is assigned a distinct color, and when ATC assigns a specific path to an aircraft, that path is highlighted or augmented with enhanced visual indicators. This allows flight crews to quickly identify their assigned path among multiple alternatives without having to consciously track and differentiate complex route characteristics, thereby maintaining ease of operation while improving reliability of path selection
Solution Approach 2:
The patent segments the multiple approach paths by providing clear visual separation through color-coding and selective highlighting. Instead of presenting a single complex multi-path procedure that requires conscious differentiation, the system divides the visual information into distinct, easily distinguishable segments, allowing pilots to immediately identify their assigned path without cognitive overload
2Productivity
If multiple different approach paths are assigned to increase airspace capacity, then productivity is improved, but device complexity increases due to multiple path characteristics
Solution Approach 1:
By color-coding multiple approach paths, the system enables complex multi-path procedures to be managed visually without increasing operational complexity for the flight crew. The color-coding system acts as an information processing layer that handles the complexity, allowing ATC to assign from multiple paths (increasing productivity) while pilots simply follow color-highlighted guidance
Solution Approach 2:
The navigation display system with its color-coding and highlighting capabilities acts as an intermediary between the complex MPA procedure design and the flight crew. This intermediary processes and simplifies the information, presenting only the relevant assigned path in an easily distinguishable manner, thereby allowing high airspace capacity utilization without burdening the operational system with complexity
3Reliability
If flight crews must consciously differentiate between multiple approach path characteristics, then reliability of path selection is improved, but ease of operation deteriorates due to increased cognitive burden
Solution Approach 1:
The patent eliminates the need for conscious differentiation by providing automatic visual differentiation through color-coding. The system handles the cognitive task of path identification by encoding path identity in color, allowing pilots to maintain reliable procedural awareness through simple visual recognition rather than complex analysis of path characteristics
Solution Approach 2:
The system creates a simplified visual copy or representation of the assigned approach path through color-highlighting on the navigation display. This visual copy emphasizes only the relevant information (the assigned path) while suppressing irrelevant details (other paths' characteristics), allowing reliable path identification without cognitive burden

AI summary
Methods, systems, and computer-readable media are described herein for displaying MPA procedures on a display unit of an aircraft. An assigned MPA approach path to an arrival runway is received at the aircraft. Data regarding a number of predefined MPA approach paths associated with the arrival runway are retrieved, and the assigned MPA approach path is displayed on the display unit in conjunction with other of the predefined approach paths associated with the arrival runway.
