Graphical Taxi Route Display for Runway Incursion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft pilots may become confused about taxi routes due to limited air traffic control frequencies, leading to potential runway incursions, as verbal instructions can be misinterpreted.
Innovation Solution
A system that includes a data link communications system and a processor to translate taxi instructions into graphical representations, displaying them on an aircraft display, with the ability to identify and display hold short instructions, reducing the likelihood of confusion by providing a clear visual map of the airport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verbal taxi instructions are used by air traffic control, then communication efficiency is maintained with limited frequencies, but pilot confusion and runway incursion risk increase
Solution Approach 1:
The patent introduces an intermediary system (autonomous vehicle with processing unit and display device) that mediates between air traffic control verbal instructions and pilot understanding. The system receives verbal instructions, processes them into graphical representations, and displays them to the pilot, eliminating the need for complex verbal communication while preventing runway incursions.
Solution Approach 2:
The patent replaces the mechanical/verbal communication system with an automated information processing system. Instead of relying on pilots to interpret verbal instructions over limited frequencies, the system automatically translates instructions into graphical displays, substituting human verbal communication with automated visual information delivery.
2Productivity
If multiple aircraft share limited air traffic control frequencies, then frequency utilization efficiency improves, but information clarity and instruction accuracy deteriorate
Solution Approach 1:
The autonomous vehicle system performs self-service by automatically receiving, processing, and displaying taxi instructions without requiring constant air traffic control intervention. The system independently manages the translation and presentation of instructions, allowing multiple aircraft to share frequencies while maintaining individual information clarity through dedicated graphical displays.
3Measurement precision
If graphical taxi route displays are implemented, then pilot understanding and instruction accuracy improve, but system complexity and equipment requirements increase
Solution Approach 1:
The processing unit and display device serve multiple functions: receiving verbal instructions, translating them into graphical representations, displaying the graphics to the pilot, and providing navigation guidance. This multi-functionality reduces the need for separate dedicated systems while maintaining high instruction accuracy through graphical presentation.

AI summary
A system and method are provided for presenting a taxi route for an aircraft at an airport. The method, for example, includes, but is not limited to receiving, by a processor, the taxi route, translating, by the processor, the taxi route into a graphical representation, displaying, on an aircraft display, a map of the airport and the graphical representation, and displaying, a location of a hold short instruction on the aircraft display.
