During May 2025, Daniel Green focused on enhancing data quality within the VATSIM-UK/UK-Sector-File repository by addressing inconsistencies in the ATS routing dataset. He implemented a naming convention alignment for en-route data, updating both the ENR files and associated test data to ensure accuracy and consistency. Using his expertise in aviation data and data management, Daniel resolved issues related to 5LNCs, which improved data integrity and reduced downstream errors for aviation sector consumers. His work, primarily involving Markdown and text-based data manipulation, contributed to the maintainability of the repository, though the scope was limited to a single bug fix that month.
