Good job on capturing the O'Hare experience :D

@N734NJ Wait until I post the one where we landed on the new north runway and taxied for 15 minutes to get around to the south side of the terminal. Now THAT is the O'hare experience!

@IADaveMark ....did you upload that one yet? just wondering

[IADaveMark]

@airplanecrazy1989 Oh... sorry I did not.

@IADaveMark How did you get the ATC? Scanner?

[IADaveMark]

@mikezc128 Can't remember if this was off of United's famous "channel 9" on board or if I pulled it from LiveATC.net the next day. I've done both.

A quick curiosity here:

I've seen some of the runway holding signs (maybe not in US but elsewhere around the world) labeled with the runway number and CAT I/II/III (e.g. 27R CAT I/II/III). What's the purpose of the "CAT I/II/III" part?

[IADaveMark]

@alcheng1000 I know that the ILS hold lines are so that taxiing aircraft don't interfere with the signals. You can find the definitions of Cat 1/2/3 on wikipedia under ILS. I'm not sure why the would be on the runway signs.

[airplanecrazy1989]

What is the purpose of "Metering" at ORD? Always heard it on channel 9 never understood it....

[IADaveMark]

@airplanecrazy1989 Aircraft will call ground metering after pushback with their location and current ATIS.

Metering will then pull AAL765's flight strip from his bay and rack it into the outbound ground controller's bay right next to him. This prevents aircraft from having to call ground and, in turn, the outbound ground controller can call the aircraft in the order in which they called metering to keep the traffic flow orderly and efficient.
