What are the two types of airspace control?

The correct choice identifies procedural and positive as the two types of airspace control.

Procedural airspace control relies on established procedures and regulations to manage air traffic, allowing aircraft to operate safely and efficiently without real-time control from air traffic personnel. This method typically involves predefined routes, altitude assignments, and specific communication protocols that pilots must follow. It is useful in situations where air traffic is less dense or when air traffic control resources are limited.

Positive airspace control, on the other hand, involves direct and continuous control of aircraft by air traffic controllers. This system is essential in busy airspace, where real-time adjustments are necessary to prevent collisions and ensure safe distance between aircraft. Controllers provide instructions, clearances, and guidance, allowing for more flexible and immediate management of airspace.

Understanding these two systems is critical for the effective management of air traffic and ensuring safety in aviation operations.
