For non-radar identified aircraft, what information should be provided in the traffic advisory?

Providing a comprehensive traffic advisory for non-radar identified aircraft is essential for maintaining situational awareness and ensuring safety in the airspace. The correct choice reflects the need to offer all relevant information to pilots, which includes distance from the aircraft, altitude, estimated time of arrival (ETA), and direction of traffic.

Distance and altitude give pilots a clear understanding of how far away the other aircraft is and at what vertical level, enabling them to assess potential conflicts and make informed decisions. Including the ETA and direction of the traffic further enhances situational awareness by informing the pilot about the anticipated path and movement of the aircraft, allowing them to anticipate how this may affect their own flight path.

All this information combined aids in decision-making processes, helping pilots to maintain separation and avoid collisions, especially in environments where they may need to rely on their visual capabilities rather than radar. Thus, providing a complete picture of the traffic situation surrounding the aircraft is not only beneficial but crucial for flight safety.
