Key Takeaways:

Air Traffic Control's core mission is to prevent aircraft collisions and ensure safety 24/7, strictly adhering to separation standards defined by FAA Order 7110.65, such as 3-5 miles lateral and 1000 feet vertical.
ATC uses a mix of radar technologies, including primary, secondary (transponder-based), and modern systems like ADS-B/WAM, which require ongoing modernization due to aging infrastructure.
Aircraft are radar-identified by ATC (commonly through discrete beacon codes) before receiving radar services, enabling controllers to track and manage flights using detailed data tags.

Keeping you safe is a big deal for us—the biggest. Air Traffic Control exists to separate aircraft from each other, from terrain, and from obstacles. We work from dawn to dawn, 24/7, 365 days a year, watching the skies and making decisions that protect you in our National Airspace System (NAS).

We have tools and rules to accomplish this? That control is based on many factors, including radar procedures, non-radar procedures, rules and regulations, plus a strong infrastructure that supports each of these techniques.
