Air traffic control is crucial for managing traffic in the skies and on the ground, providing guidance and instructions to pilots to prevent collisions and ensure smooth operations.

Simply including airmen and ATC also excludes the critical infrastructure of airports. Finally, while military operations are an important aspect of aviation, they are only part of the larger NAS, which also accommodates civilian aviation.

Understanding the interrelationship of these components is essential for grasping how the NAS operates as a cohesive system, ensuring safety and efficiency for all types of air traffic
