Which statement about Class B airspace entry is true?

• A. You must have ATC clearance to enter
• B. Radio communications are not required
• C. No transponder is required
• D. You may enter anytime without authorization

Answer: (D)

Entering Class B airspace requires explicit authorization from ATC. This airspace is tightly controlled to protect busy airports, so you can’t legally enter without a formal clearance, which for drones is obtained through LAANC or another FAA-approved authorization that specifies where you may operate, at what altitude, and for what time window. The clearance itself is the legal permission to enter, and you must comply with its terms. Radios and transponder rules are part of the broader airspace requirements, but the essential point for entry is obtaining that ATC clearance first. For manned aircraft, a functioning transponder with altitude reporting is typically required in Class B, whereas drones don’t rely on a transponder, reinforcing that the key rule is getting ATC authorization before entering.
