What is one of the primary benefits of ADS-B In for pilots?

One of the primary benefits of ADS-B In for pilots is the ability to see the location of other nearby aircraft. This technology enhances situational awareness by providing cockpit displays that show other aircraft in the vicinity, along with their altitude and flight paths. This real-time information is crucial for maintaining safety and efficient navigation, especially in busy airspace or during visual flight rules (VFR) operations.

The other options do have their own advantages but are not primary features of ADS-B In. For instance, while automated weather updates and ground proximity alerts contribute to safe flying, they are not the defining functionalities of ADS-B In technology. Real-time engine diagnostics, on the other hand, relate to aircraft maintenance and performance rather than situational awareness in the airspace. Hence, the capability to visualize other nearby aircraft is distinctively a key feature of ADS-B In, significantly contributing to improved safety and operational efficiency in aviation.
