Which service is described as an air-ground communication facility operated by a non-ATC private agency advisory service?

• A. Flight Service Station (FSS)
• B. UNICOM
• C. CTAF
• D. ATIS

Answer: (A)

Flight Service Station is the air-ground communication facility you use for formal advisory services like weather briefings, flight planning, and flight information, and it’s operated by a private contractor under FAA oversight rather than by air traffic control. It serves as a two-way advisory link for pilots, separate from ATC’s role in controlling air traffic. UNICOM and CTAF are on-field advisory channels used at airports without an operating control tower; they’re for general coordination between pilots rather than official weather briefings or flight planning. ATIS is an automated, continuous broadcast of current weather and airport information, not a two-way advisory service.
