What is a requirement for ADS-B Out as of January 1, 2020?

  1. Must broadcast GPS position to ground stations

  2. Must provide weather information to the cockpit

  3. Must operate without any user input

  4. Must only function during VFR flights

The correct answer is: Must broadcast GPS position to ground stations

The requirement for ADS-B Out as of January 1, 2020, includes the necessity to broadcast GPS position to ground stations. This is essential for the functioning of ADS-B, which stands for Automatic Dependent Surveillance–Broadcast. The system relies on GPS technology to determine an aircraft’s precise location, which is then transmitted to ground stations and other aircraft. By broadcasting accurate GPS position data, ADS-B enhances situational awareness and allows air traffic control to monitor and manage air traffic more efficiently. Broadcasting position data is critical for maintaining safety in crowded airspace and for the implementation of reduced separation standards. Without a reliable position signal from the aircraft, the effectiveness of the ADS-B system in providing situational awareness and facilitating air traffic control operations would be severely compromised.
