Portable Computer Intermediary for Aircraft Database Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for updating aircraft navigation databases (NAVDB) lack reliable monitoring, tracking, and auditing, leading to potential errors in data distribution and billing, especially since aircraft are not typically connected to the internet during updates.
Innovation Solution
A portable, hand-held computer such as an electronic flight bag (EFB) or tablet serves as an intermediary between the database server and aircraft, providing data upload validation and auditing to ensure accurate billing and authorization of database usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable computer is used as an intermediary for data upload, then auditing and billing reliability is improved, but device complexity increases
Solution Approach 1:
A portable computer serves as an intermediary device between the database server and the aircraft's flight management system. This intermediary performs authentication of the aircraft identifier, validates the database update package, and provides auditing capabilities, thereby resolving the contradiction by introducing a dedicated mediating component that handles the complex verification tasks without requiring the main aircraft systems to become more complex
2Manufacturing precision
If per-aircraft authentication is implemented, then data distribution accuracy is improved, but operational time increases
Solution Approach 1:
The portable computer performs authentication of the aircraft identifier and validation of the database update package in advance, before the actual data upload to the flight management system. This preliminary verification ensures data distribution accuracy while minimizing operational time impact, as the authentication process is completed beforehand rather than during the critical data loading phase
3Ease of operation
If local data means are used for database updates, then ease of operation is improved, but monitoring capability deteriorates
Solution Approach 1:
The portable computer provides feedback by recording audit information about the database update process, including which aircraft received updates and validation results. This feedback mechanism maintains ease of operation through simple local data transfer while simultaneously restoring monitoring capability through systematic recording and tracking of update operations

AI summary
A portable, hand-held computer functions as an intermediary between a database server and individual aircraft when the aircraft cannot be connected to the database server. By virtue of being portable and being locally linked (over time) to different aircraft, the intermediary computing device can provide the data upload validation and auditing for accurate billing of database usage for a flight database provided from the server. This ensures that each aircraft which receives an uploaded database is entitled to receive the upload based on a paid license. As a result, billing by the database vendor is based on usage. Licensing and data authentication is mediated by the intermediary computing device.
