Which statement accurately describes the major airspace classes and the basic VFR requirement in controlled airspace?

• A. Class A allows VFR with standard weather minimums.
• B. Class B, C, and D require two-way radio communication and ATC clearance; Class A IFR only.
• C. Class A IFR only; Class B, C, D require two-way radio communication and clearance; Class E and G have varying requirements; VFR flight typically requires visibility and cloud clearance appropriate to airspace.
• D. Class E and G always require explicit clearance for all flights.

Answer: (C)

The main idea is how airspace classes govern what you can do under VFR and what kind of ATC interaction is required. In the highest, IFR-only space, VFR isn’t allowed, so Class A being IFR only is the anchor of the rules. For the other controlled classes, pilots must establish two-way radio communication with ATC before operating there, and entering the more restricted Class B requires explicit ATC clearance. In Class C and Class D, being in two-way communication with ATC and following their instructions is required to operate within those areas. Class E and Class G have varying rules because Class E is controlled but does not always require ATC clearance for VFR, while Class G is largely uncontrolled, with weather and visibility requirements that depend on altitude and time of day. The common thread for VFR across all airspace is that you must meet the visibility and cloud clearance requirements appropriate to the airspace you’re in.
