Wireless Flight Recordation for Remote Black-Box Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight recorders, or 'black-boxes', often suffer severe damage in aviation accidents, making data recovery impossible, and in some cases, the aircraft cannot be located, preventing determination of the incident causes.
Innovation Solution
A wireless flight recordation system for real-time collection and remote storage of black-box data using black-box data collectors connected to sensors via direct or indirect methods, including signal splitters/duplicators and contactless sniffers, to transmit data via wireless communication networks to a remote location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight recorders are installed in the rear part of the aircraft to survive crashes, then the reliability of data preservation is improved, but the difficulty of data recovery worsens when the aircraft cannot be located or the black-boxes suffer severe damage
Solution Approach 1:
The system performs preliminary data backup by continuously transmitting flight data from the black-box to a remote server via wireless communication during normal flight operations. This advance action ensures data is already stored remotely before any accident occurs, eliminating the need to physically recover the damaged black-box for data retrieval.
Solution Approach 2:
The invention creates a digital copy of the flight data stored in the black-box and transmits it to a remote server. This copying approach allows the original black-box to remain in its protective location while a duplicate of the data exists remotely, ensuring data availability even if the original is damaged or lost.
2Strength
If flight recorders are protected with heat-resistant coating and mounted in the tail section, then the strength and resistance to extreme conditions is improved, but the ease of operation for data extraction worsens when the aircraft is lost
Solution Approach 1:
The system replaces the mechanical approach of physically recovering and opening the black-box for data extraction with an electronic/wireless transmission system. Data is automatically transmitted via wireless communication networks to a remote server, eliminating the need for physical manipulation of the protected black-box and enabling easy data access regardless of the aircraft's location or condition.
3Productivity
If real-time wireless transmission of black-box data is implemented, then the productivity of data backup is improved, but the use of energy by the system worsens
Solution Approach 1:
Instead of continuous real-time transmission, the system implements periodic data transmission where flight data is buffered and transmitted at intervals or when connectivity is available. This approach maintains high data backup productivity over time while significantly reducing instantaneous energy consumption compared to continuous transmission.
Solution Approach 2:
The system performs preliminary data buffering and preparation before transmission occurs. Data is collected and staged in memory during flight, then transmitted in batches when wireless connectivity is available, reducing the need for constant high-power transmission while maintaining comprehensive data backup.

AI summary
A wireless flight recordation system is disclosed for collecting black-box data of an aerial platform. The wireless flight recordation system includes one or more black-box data collectors for collecting black-box data that is recorded by one or more flight recorders of the aerial platform. The wireless flight recordation system also includes at least one data transmission interface connectable to the black-box data collectors for receiving the black-box data and establishing a wireless communication link with a wireless data communication network which is capable of providing data communication services to the aerial platform during flight. The data transmission interface transmits the black-box data or at least a parts thereof, via the wireless data communication network, to a receiver remote from the aerial platform. In some implementations the black-box data collectors are adapted to interface (e.g. sniff) one or more black-box cables, which provide data feed to the one or more flight recorders, to thereby indirectly receive the black-box data.
