How does airspace classification affect VFR operations?

• A. Different classes have minimum weather, visibility, and clearance requirements; some require ATC clearance or VFR separation, others permit unrestricted VFR with appropriate separation.
• B. All classes require ATC clearance.
• C. Weather criteria are the same across all classes.
• D. VFR operations are always unrestricted regardless of class.

Answer: (A)

Airspace classification sets different rules for VFR flight by changing the weather minimums, visibility and cloud clearance requirements, and the entry and traffic-management rules you must follow. In some airspace, you must obtain ATC clearance to enter and ATC may provide separation for traffic, including VFR, as needed. In other airspace, you can operate VFR without a specific entry clearance, but you must be in two-way radio contact with ATC and you’ll be managed and warned by ATC as appropriate. In still other airspace (often uncontrolled), you fly VFR using standard weather minimums and rely on see-and-avoid, with no ATC separation unless you’re explicitly assigned. So where you are in the airspace determines what you must do before and during the flight, and whether ATC clearance or separation is required.
