The document summarizes the remote air-ground communication services provided by the Tokyo Flight Service Center (FSC) for small airports in Japan. The Tokyo FSC uses a REMOTE-AFIS system to provide air traffic services like clearance delivery and aerodrome advisories for airports without control towers. A single flight information officer remotely handles air traffic communication for multiple small airports using cameras, radios, and data links with airport operators and air traffic control. The system ensures safety through agreements with local weather services and area control centers for coordination.
