What does preventive control eliminate compared to airport traffic control?

Preventive control primarily focuses on eliminating the need for repetitious, routine approval of pilot actions by implementing proactive measures that ensure safety and efficiency in air traffic management. This approach anticipates potential issues and takes steps to prevent them before they occur. As a result, pilots can operate with greater autonomy, reducing the frequency of routine interactions with air traffic control for standard approvals.

In contrast, routine conflict resolution, standardized communication, and emergency situation management are all integral parts of air traffic control but do not specifically relate to the primary focus of preventive control. While conflict resolution addresses specific situations as they arise and communication ensures all parties are informed, these functions do not aim to eliminate routine approvals; rather, they complement the ongoing operational processes necessary for maintaining safety in airspace.
