Worked on updating the Cairo FIR and aerodrome boundaries in the lennycolton/vatglasses-data repository to comply with ARIAC 2604 regulations. Focused on airspace management and data management, the work involved revising borders, aerodrome coordinates, and sector definitions to ensure regulatory compliance and improve routing accuracy. Leveraged JSON for precise data updates, maintaining full traceability through detailed commit messages. No major bugs were addressed during this period, as the primary contribution centered on enhancing data quality and regulatory alignment. The updates supported safer planning and operational decisions by ensuring the airspace management system reflected the latest aviation requirements and standards.
