Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft distress tracking systems face challenges such as separate and unsynchronized installations of Emergency Locator Transmitters (ELTs) and Autonomous Distress Trackers (ADTs), leading to ineffective emergency notifications and increased installation, training, and operational costs due to varied interfaces and lack of integration.
Innovation Solution
The integration of ADTs and ELTs through a common interface architecture that supports various coupling configurations, allowing for reuse of existing crew interfaces and synchronization of emergency broadcasts, enhancing the reliability and efficiency of aircraft distress location tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate stand-alone installations of ELT and ADT are used, then installation flexibility is maintained, but device complexity and operational costs increase
Solution Approach 1:
The patent merges the ELT and ADT into a single integrated unit that combines emergency location transmission and autonomous distress tracking functions. This integration reduces the number of separate components and interfaces while maintaining the ability to perform both ELT and ADT operations through a unified system architecture.
Solution Approach 2:
The integrated unit is designed to perform multiple functions - it can operate as a traditional ELT, as an autonomous ADT, or in hybrid modes. The system universally supports various coupling configurations (loosely coupled, medium coupled, tightly coupled) to adapt to different operational requirements and regulatory environments.
2Stability of the object's composition
If separate ELT and ADT installations are used, then existing systems can be maintained independently, but emergency response effectiveness decreases due to unsynchronized activation
Solution Approach 1:
The integrated unit incorporates feedback mechanisms that allow the ADT and ELT components to communicate their status and activation states. This enables synchronized operation where the system can detect distress conditions through either component and coordinate the emergency response activation of both functions simultaneously.
Solution Approach 2:
The system performs preliminary actions by pre-configuring multiple coupling modes that enable coordinated activation. The integrated design allows the ADT to monitor aircraft parameters and prepare for autonomous activation, while the ELT component is pre-configured to respond to both manual and automatic triggers, ensuring synchronized emergency response.
3Reliability
If multiple separate emergency systems are installed, then comprehensive coverage is achieved, but training requirements and crew workload increase
Solution Approach 1:
The integrated unit provides comprehensive emergency coverage through its ability to perform ELT, ADT, and hybrid operations. The unified interface and single unit design reduce crew training requirements while maintaining comprehensive emergency response capabilities across multiple operational modes.
4Ease of manufacture
If integrated ADT-ELT configurations are implemented, then installation costs and training requirements are reduced, but integration complexity increases
Solution Approach 1:
The integrated unit is designed with segmentable functional modules that can be configured in different coupling modes. This segmentation allows the system to be installed and integrated with varying degrees of complexity depending on the desired level of integration, from loosely coupled to tightly coupled configurations.
Solution Approach 2:
The system incorporates dynamic configurability that allows it to adapt its integration level with aircraft systems. The integrated unit can operate in different coupling modes (loose, medium, tight) depending on the aircraft's existing avionics architecture, reducing integration complexity while maintaining comprehensive functionality.

AI summary
Aircraft tracking and emergency location avionics architectures that integrate existing fixed Emergency Locator Transmitter (ELT) installations, their associated aircraft avionics systems and existing flight deck interfaces with an Autonomous Distress Tracker (ADT) transceiver unit in a coupled configuration. Some of the architectures allow the ADT unit and its advanced distress detecting and reporting capabilities to monitor the activation control path for the ELT and the associated ELT activation outputs. Other architectures place the ADT unit and its advanced distress detection capabilities and ground-controlled capabilities in the activation control path for the ELT. Additional architectures entail the connection of an ADT unit to an ELT remote panel on the flight deck of an aircraft.
