  • Provide aviation managers tools and capabilities to enhance aircraft coordination within the national airspace.
  • Promote safe, consistent, and standardized approaches to addressing airspace and land management responsibilities on and above lands managed by the member agencies.
  • Identify airspace management and coordination responsibilities among entities sharing the national airspace.
