@NathanG - I there is definitely some overlap between the functions of the FAA flight service station and that of air traffic control. I see the service station as helping to alleviate some burdens on air traffic control by providing general flight and advisory information.
Given the overlap however the question remains how long some of these stations will remain open. The FAA has closed some stations and consolidated others. Will this trend continue? I don’t know.
I am not sure if this is motivated by economic concerns or because they see some redundancy in the functions of the stations. I am all for efficiency but I think the flight service stations play an important role and should remain open.
