Which statement about Class B airspace entry is true?

• A. ATC clearance, two-way radio communication, and a Mode C transponder are required.
• B. Two-way radio communication is the only requirement.
• C. ATC clearance is not required.
• D. No special entry requirements apply.

Answer: (A)

Entry into Class B airspace is tightly controlled: you must have ATC clearance to enter, establish two-way radio communication with ATC before or as you enter, and be equipped with a transponder that provides altitude information (Mode C), with ATC assigning you a discrete code. ATC clearance confirms you’re authorized to enter and enables separation from other traffic; two-way communication keeps ATC and the pilot connected for instructions and updates; the Mode C transponder allows ATC to identify your aircraft and monitor its altitude, which is essential in such busy airspace. Without any of these—clearance, communication, or a Mode C transponder—the entry into Class B is not permitted. The other options omit one or more of these requirements, so they don’t fit the reality of Class B entry rules.
