How does a pilot use ATC services during a flight?

A pilot primarily uses Air Traffic Control (ATC) services during a flight to receive traffic advisories and navigation guidance. This is crucial for ensuring safety and efficiency in air traffic operations. ATC provides essential information about other aircraft in the vicinity, which helps pilots maintain safe separation. Additionally, ATC offers navigation assistance, including routing changes, altitude adjustments, and direction, which enhances the flight's efficiency and safety.

While communication about turbulence may occasionally be part of pilot-ATC interactions, it is not the primary function of ATC services. Options related to entertainment or passenger notification do not align with the operational role of ATC as their focus is on flight safety and coordination rather than providing entertainment. Lastly, although ATC facilitates coordination among pilots, it does not primarily involve direct communication between them. Instead, ATC acts as an intermediary to manage airspace and communicate pertinent information to pilots, making traffic advisories and navigation guidance the correct emphasis of ATC services during a flight.
