Which term describes airspace with limits on aircraft operations?

The term that describes airspace with limits on aircraft operations is "Special Use Airspace." This type of airspace is designated for specific purposes that may restrict the general use of that airspace by other aircraft. It includes areas where certain activities, such as military training exercises or hazard areas, take place, often requiring the establishment of restrictions to ensure safety and efficiency.

Special Use Airspace encompasses various classifications, such as restricted areas, prohibited areas, and warning areas, each serving a different purpose but all limiting aircraft operations to varying degrees.

In contrast, temporary flight restrictions are typically issued for short-term events and do not encompass permanent or designated areas, while restricted airspace specifically refers to areas where flight is not allowed without prior coordination and clearance. "Controlled Flight Area" is not a standard term used in airspace classification and does not accurately capture the nature of restrictions placed on aircraft operations.
