What is an automatic dependent surveillance-broadcast (ADS-B)?

• A. A technology for monitoring engine performance
• B. A system that allows aircraft to determine their position via satellite
• C. A manual navigation tool
• D. A protocol for data encryption

Answer: (B)

An automatic dependent surveillance-broadcast (ADS-B) is a system that allows aircraft to determine their position via satellite. It utilizes Global Navigation Satellite System (GNSS) data to provide accurate real-time position information. This technology enhances situational awareness in the air traffic environment, as it broadcasts an aircraft's position, velocity, and intent to other aircraft and ground stations. The 'dependent' part of ADS-B indicates that the system relies on sensors (like GPS) to determine its position, while 'automatic' refers to the automated nature of the broadcasts made by the aircraft without pilot intervention. This capability is crucial for improving safety and efficiency in air traffic management, especially in areas where radar coverage is limited. In contrast, the other options describe functionalities that are not associated with ADS-B. Monitoring engine performance is a different aspect of aircraft telemetry, manual navigation tools do not involve automated broadcasting or reliance on satellite data, and data encryption protocols relate to information security rather than positional awareness in aviation.
