Why may controllers issue traffic advisories?

Controllers issue traffic advisories primarily to enhance pilot situational awareness. When air traffic controllers provide traffic advisories, they inform pilots about the proximity and movement of other aircraft in the vicinity. This information is crucial for maintaining safe distances between planes, especially in busy airspace where visual separation can be challenging. By enhancing situational awareness, pilots can make more informed decisions regarding altitude changes, course adjustments, or speed modifications, thereby improving overall safety and efficiency in flight operations.

While advising ground handling teams or confirming maintenance checks are important aspects of operational efficiency, they are not the primary purpose of traffic advisories. Similarly, while providing information on runway conditions is crucial, it does not relate to the advisory function aimed at enhancing situational awareness among pilots navigating their aircraft in the airspace.
