provide standard en route flight services (weather briefing, flight-planning and commsearch). FSSs provide airport advisories, vehicle control, weather observations, clearance delivery, emergency assistance, and some provide Remote Aerodrome Advisory Services. FSSs are responsible for the safe and efficient movement of aircraft on manoeuvering areas and within their designated control zone. Most FSS stations are open 24/7; some have limited hours. They are no longer responsible for flight planning, except for sending departure and arrival messages to the appropriate FIC. The FICs have assumed the responsibility for flight plans, filing, in-flight alerting, flight plan closures, interpretive weather briefings and NOTAM (NOtices To AirMen) management. The FICs also have large areas they are overseeing and have networks of RCOs, some of which are co-located with FSS or air traffic control sites. The FICs are similar in function and scope to the FAA's former automated FSS system in the United States. North Bay FIC is tied into the North American Aerospace Defense Command (NORAD) North Warning System (NWS) radar system, and has a network of 23 RCOs located across Canada's Arctic coast. Quebec City, North-Bay and Kamloops FIC also assist and oversee the "Community Aerodrome Radio Station" (CARS) program. References External links Leidos Flight Service Air traffic control
