ATC Feeds .. What's The Difference?

Wed Apr 19, 2006 6:54 am

I often like to hear Live Air Traffic Control feeds.

But for example, In Boston.
I can hear; Boston Tower - Boston Clearance/Ground AND Boston Appr/Departure.

What's the difference between them ?

TWR is the Tower
Clearance/Director will provide departure cleance and innital taxi clearance
App will be lining em up landing..then pass em to the TWR
Dep will be seperating em for climb and airways .... rec'd from the TWR

TWR will deal with Live Runway Traffice ONLY

generally the flow will be as follows:

Clearance: When at the terminal an aircraft will call up clearance, and ask for permission to fly. Once the flight plan is filed clearance will give permission if everything is ok.

Ground: Aircraft will now call up ground and ask for permission to start up engines and push back from stand, then once done, permission to taxi to the runway.

Tower: Once the aircraft has taxiid to the assigned runway and stopped short at the designated holding point, they will call up tower. Tower will then give them permission to enter the runway and takeoff when it is safe to do so.

Departure: Immediately after takeoff the ac will be passed to departure, who will guide the ac along the designated departure route, and climb the aircraft to transition altitude.

Center: once the aircraft either reaches a certain altitude or waypoint they will be passed over to center, who then guide the aircraft all the way to the next airport. Multiple centers will be contacted, each covering a specific patch of airspace.

Once nearing destination the aircraft will be told to descend by center, then once a certain point is reached, control is passed to approach.

Approach: will space the aircraft out from all the others, putting them into a hold as necessary. Once they are spaced and are about 10-20miles from the runway established on the approach they are handed to tower

Tower: clears the ac to land as soon as runway is clear. Once landed and clear of the runway, back to ground

Ground: assigns a gate to the ac and clears the ac to taxi to this gate along the designated route

Quoting Jerplane (Reply 2):

Oh yes there is, i don't think DCA is on here, but http://www.liveatc.net/ has looooads of airports with live ATC. I don't know whether they have all the Tower, Approach, Ground etc, JFK does but not sure on all the rest. On some of the feeds, the SFO for example, when it loads up in Windows Media player, you can choose to have either the left or the right speaker playing, (there's a setting somewhere) and the left side has the Twr, and the right has clearance.

Yeah that's a great website to listen to. When you get to it, click on Live ATC Audio Feeds on the left and choose 'All' and then that's all of the feeds you can listen to!

Hope it all helps!!

Nighthawk :
"Ground: assigns a gate to the ac and clears the ac to taxi to this gate along the designated route"

I cannot think of a ground controller who will actually assign a flight to a gate, usually the airline's operations will do all of the when the crew calls in range, or ACARS will give the crew that Information based on what gate is assigned to them from airline operations or the airport operations. The crew will tell the ground controller what gate he is going to, and the ground controller will either direct him to the gate, or just tell him to taxi to that gate.

"Clearance/Director will provide departure cleance and innital taxi clearance"

Unless the Clearance controller is working both ground and clearance, he or she will not provide initial taxi clearance. Like I said there are expect ions, like when it is late at LAX the ground controller will also handle clearance, but usually the controller will have the aircraft switch to the different frequencies even though its the same person working the two positions.
