Unified Data Link Interface for FANS and ATN Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic control systems are incompatible, limiting aircraft to use either FANS or ATN data link technologies during different phases of flight and requiring separate training for aircrews due to different operator interfaces.
Innovation Solution
A system and method that allow communication using multiple air traffic control data link standards through a common operator interface, featuring a selector component, initiator, adapter, encoder, transmitter, and display components to facilitate communication with ATC centers using either FANS or ATN standards, enabling a single aircraft to implement both technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an aircraft is equipped with both FANS and ATN data link technologies, then the aircraft can communicate with different air traffic control centers using appropriate standards during different phases of flight, but the system complexity and cost increase significantly
Solution Approach 1:
The operator interface is designed to support multiple data link standards (FANS and ATN) through a single unified system. The interface can adapt its functionality based on the selected standard, allowing one system to perform multiple functions rather than requiring separate dedicated systems for each standard.
Solution Approach 2:
An adapter component is introduced as an intermediary layer between the operator interface and the data link standards. This adapter translates and adapts messages between different standards, allowing the operator interface to communicate with both FANS and ATN systems without requiring separate interface designs for each standard.
2Reliability
If separate operator interfaces are provided for FANS and ATN systems, then each interface can be optimized for its specific standard, but aircrew training time increases due to learning multiple interfaces
Solution Approach 1:
A single operator interface is designed to handle both FANS and ATN standards, eliminating the need for separate interfaces. The interface adapts its behavior and message formats based on the selected standard, providing a unified learning experience for aircrew while maintaining standard-specific functionality.
Solution Approach 2:
The operator interface dynamically adjusts its characteristics based on the selected data link standard. When FANS is selected, the interface presents FANS-specific options and formats; when ATN is selected, it presents ATN-specific options. This dynamic adaptation allows one interface to serve multiple purposes without requiring separate training for each mode.
3Ease of operation
If a single operator interface supports multiple data link standards, then training time is reduced and operational flexibility is improved, but the interface complexity and message formatting requirements increase
Solution Approach 1:
The adapter serves as an intermediary that handles the complexity of message formatting and standard-specific requirements. This shields the operator interface from the full complexity of multiple standards, allowing the interface to remain relatively simple while still supporting both FANS and ATN through the adapter's translation and adaptation capabilities.
