What is the main purpose of using Keyhole usage in airspace management?

The main purpose of using Keyhole usage in airspace management is to establish a reconnaissance anchor point. This strategy enables the efficient management of airspace by designating specific locations where reconnaissance operations can be conducted. It allows for effective monitoring and surveillance of designated areas while ensuring that air traffic is managed to minimize conflicts and enhance safety. Utilizing keyhole points helps in maintaining situational awareness and can support various operations, including intelligence collection and target identification.

Options that imply secure landing zones or supply drop coordination, while relevant to air operations, do not specifically align with the reconnaissance aspect that Keyhole usage emphasizes. Adjusting flight altitudes quickly pertains more to dynamic flight operations rather than the specific anchor point concept inherent in Keyhole usage.
