Can you fly through Class F airspace?

Class F airspace is classified as a type of airspace in which operations can vary depending on the status or use of that airspace. It can be designated as either "advisory" or "restricted." When the airspace is designated as "advisory," it means pilots are informed about certain conditions or activities that could affect flight safety, but it is not restricted. Therefore, flying through this type of Class F airspace is allowed under the appropriate circumstances, provided that pilots exercise caution and maintain situational awareness.

In contrast, if the Class F airspace is marked as "restricted," flight is not permitted without special permission, which emphasizes the necessity for pilots to be aware of such designations. The choice to indicate that you can always fly through Class F airspace does not account for operational restrictions that might apply, and stating that flying is never allowed lacks acknowledgement of the advisory nature of certain Class F airspace.

Thus, the correct answer emphasizes the nuanced rules governing Class F airspace and aligns with regulations that allow flight through it under specific conditions, particularly when it's marked as "advisory."
