ADS-B stands for

• A. Automatic Data Surveillance-Broadcast
• B. Automated Detection and Surveillance-Broadcast
• C. Auto-dependent Surveillance-Broadcast
• D. Automatic Dependent Surveillance-Broadcast

Answer: (D)

ADS-B stands for Automatic Dependent Surveillance-Broadcast. The word “automatic” means the system operates without manual input, with data being sent by the aircraft itself. “Dependent” indicates the position and velocity data come from the aircraft’s own navigation systems, such as GPS, rather than from ground radar. “Surveillance” reflects its role in tracking and monitoring an aircraft’s location, and “Broadcast” means that this information is transmitted out to ATC and other equipped aircraft over a data link, rather than being pulled by radar. In short, the aircraft automatically and continuously broadcasts its GPS-derived position and velocity to improve situational awareness and airspace efficiency, especially where radar coverage is limited.
