What is true about entering Class D airspace?

• A. Requires a pilot to maintain 5 miles visibility at all times
• B. Requires you to establish two-way radio communication with ATC prior to entry
• C. Requires explicit ATC clearance to enter
• D. Has no weather minimums

Answer: (B)

Entering Class D requires establishing two-way radio communication with ATC prior to entry. This ensures ATC can acknowledge you, provide traffic advisories, and coordinate sequencing as you operate within the controlled airspace around a towered airport. For VFR flight, you don’t need an explicit clearance to enter Class D—simply be in two-way contact with ATC and follow their instructions. If you’re flying IFR, you would need ATC clearance to enter. Also, remember that Class D has weather minimums for VFR: typically 3 statute miles of visibility and cloud clearance of 1,000 feet above, 500 feet below, and 2,000 feet horizontally.
