What is Flight Services Station (FSS) responsible for?

The Flight Services Station (FSS) plays a crucial role in supporting pilots by relaying air traffic control (ATC) clearances and providing vital information. FSS serves as a resource for pilots, offering services such as weather briefings, flight planning assistance, and information on navigational aids. When it comes to ATC clearances, FSS is responsible for ensuring that pilots receive necessary information to operate safely and effectively in the airspace, especially in areas where there may not be a direct ATC service available.

In contrast, the other options involve functions that are not within the scope of FSS duties. Air traffic control clearances are primarily handled by ATC facilities rather than FSS. The control of descent for aircraft is also a responsibility of air traffic controllers, who manage the safe sequencing and separation of aircraft within their controlled airspace. Finally, training pilots for emergency situations falls under the purview of flight schools and aviation training organizations, not FSS. Therefore, the role of FSS is specifically centered around relaying clearances and information to enhance pilot safety and situational awareness.
