Pulse Radar Assessment Complete Practice Test 2025

The correct understanding is that ADS-B (Automatic Dependent Surveillance–Broadcast) avionics are designed to automatically broadcast critical flight information, including identification, position, altitude, velocity, and additional data components. This broadcast occurs at a frequency of twice every second, allowing air traffic control and other aircraft to receive timely updates about the aircraft's status.

The functionality of ADS-B relies on inputs from various subsystems, such as GPS for accurate positioning and onboard sensors for altitude and velocity, thus ensuring continuous and reliable data dissemination without requiring pilot intervention. This automation enhances situational awareness for both air traffic controllers and nearby aircraft, contributing to increased safety in the airspace.

Other options do not accurately reflect the capabilities of ADS-B avionics. Some suggest that specific data like altitude and speed are only transmitted, while one implies a manual input requirement, which contradicts the automated nature of ADS-B. Overall, the correct choice emphasizes the robust capabilities and automated broadcasting feature of ADS-B systems, essential for modern air traffic management.
