Which statement about ADS-B Out near Class B airspace is true?

• A. ADS-B Out is required within 30 miles of a Class B primary airport up to 10,000 feet MSL, with certain exceptions
• B. ADS-B Out is never required in the vicinity of Class B
• C. ADS-B Out is required above 60,000 feet MSL only
• D. ADS-B Out is required only for IFR flights

Answer: (A)

ADS-B Out is required in the Class B environment within a specific zone around the primary airport. Specifically, if you’re within 30 nautical miles of the Class B primary airport and from the surface up to 10,000 feet MSL, ADS-B Out must be operating. This rule is in place so ATC can reliably identify and track aircraft in the busy airspace around major airports. There are some exceptions defined in the regulations, but the main point to remember is the 30 NM radius and the 10,000 ft ceiling. The other statements aren’t correct because ADS-B Out is indeed required near Class B (not “never”), it isn’t limited to operations above 60,000 ft, and it applies to more than just IFR flights.
