Which aspect of aviation do Flight Service Stations (FSS) not directly assist with?

Flight Service Stations (FSS) play a crucial role in supporting pilots by providing a range of services that enhance flight safety and efficiency. Among these services, they offer pilot briefing, which includes pre-flight planning and route information; weather information, which covers current conditions and forecasts critical for flight decisions; and en route communication, which ensures pilots receive vital updates and assistance while in flight.

Ground handling services, however, are not within the direct purview of Flight Service Stations. These services typically encompass aircraft servicing activities that occur on the ground, such as fueling, maintenance, baggage handling, and passenger services. Ground handling operations are usually managed by airport authorities or specialized ground handling companies rather than FSS. Therefore, the correct choice highlights the specific area where Flight Service Stations do not have a direct role, underscoring their focus on flight-related support rather than ground operations.
