Which ATS airspace classification permits IFR and VFR, with IFRs under ATC service and all flights receiving traffic information as far as is practical?

• A. Airspace D
• B. Airspace B
• C. Airspace E
• D. Airspace A

Answer: (C)

In ATS airspace, the classification that fits both IFR and VFR operations with IFR under ATC service and traffic information provided to all flights as far as is practicable is airspace where the airspace is controlled but not restricted to instrument flight only. In this class, IFR traffic is under ATC clearance and separation, while VFR pilots may operate with the benefit of traffic advisories from ATC as far as workload and radar coverage permit. This combination of IFR being actively managed by ATC and VFR receiving practical traffic information is what distinguishes this class from others where either VFR is restricted, or all operations require explicit clearance.
