• Ensuring compliance with regulatory requirements and industry standards
• Managing budgets and resources for facility development and maintenance
• Coordinating with other stakeholders, including air traffic control, airlines, and airport authorities
• Overseeing the maintenance and repair of airway facilities and equipment
