What are the entry requirements for Class B airspace?

• A. ATC clearance, two-way radio communication, and a Mode C transponder.
• B. Visual flight rules only.
• C. No radio required if in VFR.
• D. Only for IFR flights.

Answer: (A)

Class B is tightly controlled around busy airports, so entering it is not about what you’re flying but about authorization and equipment. You must have an ATC clearance before you enter, you must establish two-way radio communication with ATC and maintain it while you’re in the airspace, and you must have a Mode C transponder for altitude reporting. These requirements let ATC safely sequence, separate, and monitor all traffic in the most congested airspace. Visual flight rules alone don’t grant entry, and it isn’t restricted to IFR flights only—both VFR and IFR operations can enter Class B as long as you have the clearance, two-way communication, and the proper transponder.
