Took a tour of Atlanta TRACON today. Old friend works there. Amazing how big it is. Almost like a center with over a dozen controllers working sectors. Things that we didn't have in the old days: - Wireless headset. Pretty cool. - Aircraft predicted track. Nice feature. - Bearing and distance to another airport. We had that but way more user friendly now. - ID tag colors for departures, inbounds & overflights. - ABCDEF weight categories???? - Exact distance between aircraft on final. Nice. - All digital approach plates. No reaching for paper in the chart bin. - No VFR strips. All info on the tag stratch pad. - Majority of the traffic inbound on STARs. No vectors. - System actually knows difference between ADS-B traffic vs non ADS-B. - One second refresh rate. - "Snitch patch" reporting. Good time in the Atlanta area. No way I'd work down there with the road traffic but it's "big time" ATC so I guess they put up with it.
