What is the role of a Traffic Advisory Service?

The role of a Traffic Advisory Service primarily involves warning pilots about nearby aircraft to enhance situational awareness and safety within the airspace. This service is crucial, especially in congested airspace, as it helps prevent mid-air collisions by informing pilots of the positions, altitudes, and movements of other aircraft in their vicinity.

While other options may involve aspects of aviation operations, they do not define the primary purpose of a Traffic Advisory Service. For instance, providing weather updates pertains more to a Weather Advisory Service, and maintenance advice relates to aircraft upkeep, which is outside the scope of traffic advisories. Likewise, assisting with flight planning is a different area of support that does not specifically align with the traffic advisory function, which focuses on traffic management and safety in the airspace.
