Which prefix is used for the Coast Guard?

The correct choice, representing the prefix used for the Coast Guard, is B, "G." This designation is a standard identifier within the aviation and maritime communities, ensuring clear and consistent communication. The "G" prefix is specifically associated with Coast Guard aircraft, allowing air traffic control and other operators to easily recognize and coordinate with these units during operations.

Other prefixes used in aviation serve different categories of aircraft; for instance, "A" generally refers to Army aircraft, while "C" is commonly linked to civilian registrations. The prefix "V" is not typically associated with any specific organization in the context of Coast Guard operations. Thus, the "G" prefix distinctly identifies Coast Guard airframes, facilitating efficient operational management and safety in airspace utilization.
