Worked on improving the accuracy and maintainability of the vatpac-technology/sops repository by focusing on documentation quality. Addressed a critical issue in the Sydney Approach procedures by correcting the terminal IDs for Sydney Approach South and North, ensuring that SAN and SAS were properly aligned with their intended operational use. Utilized Markdown to implement these changes, emphasizing clear commit messages to enhance traceability and change history. No new features were introduced during this period, as the primary focus was on refining existing documentation to reduce the risk of misinterpretation and support onboarding and operational reliability for future contributors.
