Define "Flight Service Station" (FSS).

A Flight Service Station (FSS) is specifically designed to provide aeronautical information and services to pilots, making option B the correct choice. FSS facilities play a crucial role in supporting flight operations by offering various services such as weather briefing, flight planning assistance, search and rescue coordination, and communication services. These services help pilots make informed decisions about their flights, particularly regarding safety and navigation.

While filing flight plans is one of the functions of an FSS, it is only a part of the broader scope of services provided, which is why not all options highlight the full purpose of an FSS. Fuel services are provided at different locations but are not a defining characteristic of an FSS. Air traffic control operations focus more on managing the flow of air traffic rather than providing the comprehensive support services that an FSS offers to pilots directly. Thus, understanding the primary role of an FSS as a source of critical information and assistance in flight operations is essential.
