What are the general entry requirements for Class Bravo airspace?

• A. ATC clearance to enter, two-way radio communications, and a functioning Mode C transponder.
• B. Visual flight rules only.
• C. Any altitude is allowed.
• D. No radio or transponder required.

Answer: (A)

Entry into Class Bravo airspace is tightly controlled to keep busy airways safe. The requirement is that you have explicit ATC clearance to enter, you must be in two-way radio contact with ATC, and you must have a functioning transponder that provides altitude information (Mode C). ATC uses this information to identify and separate aircraft as you operate in the high-traffic area around major airports. The other options don’t fit because you can’t enter Class Bravo without clearance, the airspace isn’t open at any altitude, and you must have radios and a compatible transponder to enter and remain there.
