According to their location, ATO facilities are divided into how many service areas?

The correct answer is that ATO (Air Traffic Organization) facilities are divided into three service areas. This classification is important for managing air traffic efficiently and ensuring safety across the national airspace system. The three service areas consist of the terminal, en route, and service centers, each serving distinct functions within the overall air traffic management framework.

Understanding these three divisions helps clarify how air traffic is organized. The terminal service area is focused on managing air traffic around airports, facilitating safe takeoffs, landings, and ground movements. The en route service area deals with aircraft flying at cruising altitudes between airports, monitoring and guiding flights through controlled airspace. Lastly, the service centers provide support and coordination services, ensuring communications and operational support across all areas.

This structure allows for optimized resource allocation, improved traffic flow, and enhances safety and efficiency in airspace management.
