What is the average range of a CZ?

The average range of a Controlled Zone (CZ) is best represented by the choice indicating 18-36 nautical miles. This range aligns with the operational standards typically observed in oceanographic and acoustic applications, where Controlled Zones define specific regions for various activities, including naval operations and environmental study.

Such a range is practical for ensuring data collection reliability while minimizing interference from external acoustic sources. The specific distance allows for effective monitoring and management of underwater activities, particularly in relation to marine life and acoustic propagation. As a result, this range is established based on research, historical data, and underwater acoustics principles, confirming its appropriateness for the scenarios typically encountered in professional maritime contexts.
