I love listening to KORD approach, but I'm a little unclear on the positions. Arrival, feeder and trip are listed (various gates), but final isn't.
Can anyone tell me what each of these does, in relation to A/C handed off from Center, and before being given to final?
at C90 the final positions are called Arrival, East, West, Center when on west flow or East and West on all other configs. the Trip controller is most of the time East Feeder who works the third or trip rwy final. a trip rwy is not a full rwy that is its a 20 A/C an hour to take over flow traffic the 2 full rwys cant accept. Feeders take hand offs from the center from the far arrival fix and feed A/C to what ever rwy the hand off controllers need the A/C to go to depending on the traffic at the time.Arrivals take handoffs directly from the center from the near fix if feeder is open or both fixes if feeder is closed.position open and close during the day depending on traffic.
