Which airspace type requires two-way radio communication with the controlling facility to enter and is typically surrounded by an approach control facility?

• A. Class D.
• B. Class E.
• C. Class B.
• D. Class C.

Answer: (D)

Two-way radio communication with ATC before entering is required in this airspace because ATC must have you in contact to manage traffic flow in a busy area served by an approach control facility. This type of airspace typically surrounds airports with an operating control tower and radar approach control, consisting of an inner core and an outer shelf. You must establish two-way communications with ATC (and comply with any required clearances) before entering. That combination of entry requirement and the involvement of an approach control facility is what distinguishes this airspace.
