Which statement is true about ADS-B OUT requirements?

• A. In domestic airspace only
• B. ADS-B Out is required to fly in uncontrolled airspace.
• C. ADS-B Out is required to fly in controlled airspace.
• D. ADS-B In is mandated

Answer: (C)

ADS-B Out requirements are about where you must broadcast your aircraft’s position and related data so ATC can see you and provide separation. In the United States, the rule is that you must have ADS-B Out when you’re flying in airspace where ATC provides surveillance in real time, which means controlled airspace (Class A, B, C, D, and most of Class E). That’s why this statement is true: ADS-B Out is required to fly in controlled airspace, because ATC relies on those Out broadcasts for safe sequencing and separation. The other ideas don’t fit because ADS-B Out is not limited to domestic airspace only, it’s specifically tied to controlled airspace rather than uncontrolled airspace, and ADS-B In is not the mandate—Out must be equipped, while In is optional for pilots.
