Flight Data Graphical Compression for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face difficulties in monitoring flight information during unusual conditions due to the need to maintain control of the aircraft and communicate with air traffic control, leading to potential misinterpretation or failure to follow instructions.
Innovation Solution
A system and method that convert flight information into graphical representations, compress them, and transmit them to a ground server, allowing for real-time assistance and reducing bandwidth usage by only sending relevant data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight information is provided in real-time to ground personnel, then the pilot can receive timely assistance, but the communication bandwidth consumption increases
Solution Approach 1:
The flight information is divided into multiple graphical representations (widgets) that can be selectively transmitted. The system segments the comprehensive flight data into discrete, manageable units that can be sent incrementally only when needed, reducing overall bandwidth consumption while maintaining real-time capability.
Solution Approach 2:
Graphical representations of flight information are pre-generated and stored on the aircraft before transmission to ground personnel. This preliminary preparation allows the system to quickly transmit only the necessary information without requiring real-time processing during communication, reducing bandwidth demands.
2Loss of information
If the pilot monitors all flight information on displays, then complete flight information is available, but the pilot's attention is diverted from aircraft controls and ATC communication
Solution Approach 1:
The system extracts critical flight information from the comprehensive display and presents it through simplified graphical representations. By taking out only the essential information and presenting it in a condensed format, the pilot can access necessary flight data without being overwhelmed by the complexity of full display information.
Solution Approach 2:
The graphical representation system acts as an intermediary between the complex flight information and the pilot. This intermediary layer simplifies and visualizes critical information, allowing the pilot to quickly understand flight status without directly processing complex data streams, thus reducing cognitive workload.
3Reliability
If comprehensive flight information is transmitted to ground server, then complete assistance is provided, but communication resources are consumed excessively
Solution Approach 1:
The system applies different levels of detail to different flight information based on local requirements. Not all flight information is transmitted with the same level of detail; instead, the system selectively compresses and transmits only the essential graphical representations and properties, reducing overall data volume while maintaining assistance completeness where needed.
Solution Approach 2:
The system changes the parameters of flight information representation by converting detailed textual or numerical data into compressed graphical formats. This parameter transformation reduces the quantity of data to be transmitted while preserving the essential meaning and assistance value of the flight information.

AI summary
A method for providing flight information to a ground server is provided. The flight information is received from an aircraft system. The flight information is converted into a graphical representation and a plurality of properties associated with the flight information. The graphical representation and the plurality of properties is stored. The graphical representation and the plurality of properties is processed to generate a compressed graphical representation and plurality of properties having a compressed file size. The compressed plurality of properties is transmitted to the ground server.
