Which class requires two-way radio communication prior to entry?

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

Answer: (A)

Two-way radio communication with the controlling facility before entering is required when you’re dealing with certain controlled airspace. In Class D airspace, which surrounds many smaller towered airports, you must contact the control tower and establish two-way radio communication prior to entry and keep it active while you’re inside. This lets ATC be aware of your presence and coordinate traffic as needed. Class E doesn’t typically require prior ATC contact to enter, unless you’re operating under IFR or in a special situation. Class B and Class C do require ATC authorization and two-way communication before entry, which is a stricter requirement than what this scenario emphasizes. Class F isn’t used in U.S. airspace.
