Remote communications outlet. Remote Communications Outlets (RCO) are remote aviation band radio transceivers, established to extend the communication capabilities of Flight Information Centres (FIC) and Flight Service Stations (FSS). Pilots can find RCO frequencies in charts or publications such as the Airport/Facility Directory or Canada Flight Supplement. The RCO is used to make a radio call to the outlet as if the pilot were making the call directly to the FSS or FIC. The outlet will relay the call (and the briefer's response) automatically. RCOs are sometimes confused with RTRs, or remote transmitter/receivers.
