Control Display Unit Taxi Route Entry Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for entering and displaying taxi routes on aircraft Flight Deck Control Display Units (CDU) are inefficient and error-prone, requiring numerous user inputs and lacking integration with flight routes, leading to increased complexity and pilot workload.
Innovation Solution
A method and system that allows pilots to efficiently enter and display taxi routes on the CDU by assigning multiple taxi route segments to separate display lines in the order received, reducing the number of user inputs and integrating taxi and flight route navigation within the existing CDU interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of taxi route on CDU is implemented, then navigation route can be displayed, but number of user inputs increases and error rate increases
Solution Approach 1:
The system automatically assigns received taxi route segments to display lines in sequential order without requiring pilot intervention. The processor autonomously manages the routing logic, reducing manual inputs while maintaining reliable route display.
Solution Approach 2:
The system provides visual feedback by displaying the assigned route segments in the order received, allowing pilots to verify the automated assignment and confirm correct route entry with minimal inputs.
2Adaptability or versatility
If separate systems are used for taxi route navigation, then taxi routing capability is provided, but device complexity increases and flight deck space is consumed
Solution Approach 1:
The patent integrates taxi route navigation functionality into the existing CDU flight management system. By merging taxi routing with the established flight navigation interface, the system provides enhanced adaptability without adding separate physical systems or increasing overall device complexity.
Solution Approach 2:
The CDU is extended to serve multiple functions - both flight navigation and taxi route navigation - through a unified interface. This multi-functionality approach allows the same hardware platform to handle diverse navigation needs without requiring additional dedicated systems.
3Loss of information
If multiple display lines are used for taxi route segments, then route information is organized and displayed, but interface complexity increases
Solution Approach 1:
The taxi route is divided into discrete segments that are individually received and assigned to separate display lines. This segmentation organizes the route information logically while maintaining a simple, systematic display structure that pilots can easily follow.

AI summary
A system and method is provided for receiving and displaying a taxiway navigation route on a control display unit having at least one entry field and a plurality of display lines. A plurality of taxi route segments are received from an entry field. The plurality of taxi route segments include at least a first taxi route segment and a second taxi route segment. The taxi route segments are assigned to separate display lines in the order in which the taxi route segments were received to form a taxiway navigation route. The taxi route segments are displayed on the control display unit in the order in which the taxi route segments were received. The display line in which the first taxi route segment is to be assigned can be selected. In addition, navigation data corresponding to the taxi route segments can be identified, retrieved, and assigned to the respective taxi route segment.
