What is the term for the separation of all air traffic within designated airspace by air traffic control?

The term that refers to the separation of all air traffic within designated airspace by air traffic control is known as positive control. This concept is crucial in maintaining safety and efficiency in airspace where numerous aircraft operate simultaneously. Positive control implies that air traffic controllers provide specific instructions, ensuring that aircraft maintain safe distances from one another and adhere to predetermined flight paths. This systematic approach minimizes the risk of collisions and improves overall air traffic flow.

In contrast, advisory control does not require the same level of enforcement and typically leaves more responsibility to pilots for maintaining their own separation while still providing guidance. Traffic management focuses on optimizing the movement of aircraft in relation to airspace usage but does not guarantee separation. Flight information service offers information to pilots regarding flight conditions, hazards, and other relevant data without providing actual traffic separation. Positive control is a fundamental aspect of air traffic management, emphasizing the critical role of ATC in ensuring that all aircraft operate safely within the airspace.
