What is NOT a role of Flight Service Stations (FSS)?

Flight Service Stations (FSS) serve several crucial roles in supporting pilots and enhancing aviation safety. They are primarily responsible for providing flight planning services, which include assisting pilots in filing flight plans and offering necessary information for their routes. They also issue briefings to pilots before their flights, ensuring that aviators are informed about weather conditions, airspace restrictions, and other pertinent information that may affect their flight.

Additionally, FSS play a significant role in monitoring weather conditions and relaying this information to pilots. Their ability to provide up-to-date weather data helps pilots make informed decisions regarding their flights.

Conducting instrument approaches, however, is not a role of Flight Service Stations. This task is typically performed by Air Traffic Control (ATC) facilities, which have the necessary equipment and trained personnel to manage aircraft during lower visibility conditions and ensure safe landings. Thus, the option that accurately reflects what is NOT a function of FSS is the one concerning conducting instrument approaches.
