What do traffic advisories provide to pilots in the ATC context?

Traffic advisories are specifically designed to notify pilots about the presence of nearby aircraft. This real-time information is crucial for maintaining situational awareness, allowing pilots to make informed decisions regarding their flight path and to ensure safety by avoiding potential collisions.

These advisories are generated based on radar data, and when air traffic control identifies an aircraft in proximity to another, they relay this information to the pilots involved. This enhances communication and coordination in the airspace, creating a safer operating environment for everyone.

In contrast, the other options pertain to different types of information that do not fall under the definition or purpose of traffic advisories. For example, flight paths, weather conditions, and filing instructions are important aspects of flight management, but they do not directly address the immediate need for awareness of surrounding aircraft, which is the primary focus of traffic advisories.
