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

Flight Service Stations (FSS) provide a variety of important functions primarily focused on assisting pilots, particularly those flying under visual flight rules (VFR). Monitoring NAVAIDs, providing VFR search and rescue services, and facilitating aircraft en route communication are all key responsibilities of FSS.

FSS staff help pilots by offering updates and information regarding weather, traffic, and navigation aids (NAVAIDs), ensuring they have the necessary support during their flights. The search and rescue operations for VFR pilots also fall under the purview of FSS, which acts to coordinate responses when aircraft are reported missing or in distress. Additionally, FSS personnel provide critical communication support for aircraft in transit, ensuring that pilots can relay information and receive crucial updates while airborne.

In contrast, aircraft maintenance services are not a function of FSS. Maintenance is typically handled by specialized aviation maintenance organizations or the airline operators themselves. FSS does not possess the facilities or expertise required to perform maintenance on aircraft, which is why that answer is not aligned with the primary functions of Flight Service Stations. This distinction clarifies the scope of services provided by FSS, focusing on pilot assistance and communication rather than maintenance activities.
