What is the primary function of Flight Service Stations?

The primary function of Flight Service Stations (FSS) is to provide essential pre-flight and weather assistance to pilots. This includes offering vital information about weather conditions, route planning, and other pre-flight briefings, which are crucial for ensuring safe and informed flight operations. FSS are designed to assist pilots primarily during the planning stages of flight and during cross-country travels by providing updates about airspace restrictions, navigation aids, and significant weather changes.

While air traffic control, managing landings and takeoffs, and coordinating air traffic security are critical roles in aviation, these responsibilities are primarily handled by air traffic control facilities and not by Flight Service Stations. FSS focuses specifically on the informational and advisory support needed before and during flights rather than directing air traffic or managing airport operations. Thus, the emphasis on pre-flight and weather assistance accurately captures the fundamental role of FSS in the aviation ecosystem.
