Dynamic Aircraft Navigation Display for Pilot Workload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigational display systems for aircraft lack the ability to dynamically adjust and filter information based on real-time state variables and user-defined rules, leading to unnecessary data presentation and increased pilot workload.
Innovation Solution
A dynamic display system comprising a processor, memory, and display that evaluates state variables and applies user-defined rules to modify the navigational map in real-time, allowing for context-aware and customizable information presentation, including the use of logic trees and data sources to determine when and how to display data on a flight map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all navigational data is displayed on the flight map, then completeness of information is improved, but pilot workload increases due to information overload
Solution Approach 1:
The display system dynamically adjusts the set of displayed state variables based on the current flight phase. During different phases (takeoff, climb, cruise, descent, landing), the system automatically presents only the most relevant parameters to the pilot, reducing information overload while maintaining completeness of critical information.
Solution Approach 2:
Different regions or aspects of the navigational display provide different levels of detail based on flight phase. The system applies local quality by customizing the information density and types of state variables shown in specific flight contexts, rather than uniformly displaying all data at all times.
2Adaptability or versatility
If the display system is customized for different airlines and procedures, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system includes pre-configured sets of state variables and display configurations for different airlines and flight procedures. These configurations are prepared in advance and stored in the system, allowing rapid adaptation to different airline requirements without requiring complex real-time customization or frequent software updates.
Solution Approach 2:
The display system is designed to serve multiple airlines and procedure types through a universal architecture that can load different configuration sets. This multi-functionality allows the same hardware and core software to adapt to various airline-specific requirements by switching between pre-defined configuration profiles.
3Adaptability or versatility
If the system updates software frequently to add new rules and state variables, then adaptability is improved, but loss of time increases due to maintenance requirements
Solution Approach 1:
New state variables, rules, and display configurations are developed and validated in advance as pre-configured packages. This preliminary preparation allows the system to incorporate new airline-specific requirements or procedure changes without requiring time-consuming on-the-fly software development or extensive maintenance interventions.
Solution Approach 2:
The system uses template-based configurations that can be copied and adapted for different airlines and procedures. Once a set of rules and state variables is established for one airline, similar configurations can be rapidly replicated and customized for others, reducing the time required to support multiple operators.
Data Source
AI summary
A display system for dynamically displaying aircraft flight information. The system includes a processor, memory, and a display. The processor is capable of communicating with the memory, the display, and a system environment of the aircraft. The processor is configured to display a flight map for the aircraft on the display, to evaluate state variable(s) dynamically representing state(s) in the aircraft system environment, and dynamically modify the flight map based at least in part on the evaluation.
