ORD ATC Frequency Help

Thu Jul 23, 2009 6:07 am

At O'Hare Airport, what frequencies are used before approach...where the pilots are told which runway to expect??

Thanks in advance!!

Don't know, but could look it up. BUt I am not home.

Yes, the ATIS broadcasts the runways in use and ATC will assign a runway. But you can request another runway if necessary due to performance, then you might get it. Usually you do if possible.

Well, the problem is...when I am spotting at ORD and trying to catch a particular plane, I find out what runway they are landing on when I listen to the approach frequency and they pass the outer marker and get cleared for landing on a particular runway. But...if I am near a different runway then I have like 2 minutes to get to the right one before the plane lands, and that is impossible.

So, is there a frequency I can listen to before the plane gets to the outer marker... so I have more time to get to the right runway before the plane lands??

Listen to the ATIS frequency. Then you hear which runways are in use. Usually at first contact with ORD approach you will get a runway assigned if there are more than one in use. If they only land on 28, then the controller will not tell every airplane which runway to expect. Only if it changes.
However the crew can request a different runway. If the runway in use is too short because of performance reasons, then you do that at first contact with ORD approach as well.
I guess ORD has several approach frequencies as it is a big airport and it depends from where you are coming.

Thanks for your help Wilco!!  Smile

When I listen to ORD approach, all I hear is the pilots reporting that they are passing the outer marker, and then the controller clears them for landing on a runway. Is that the pilot's first contact with ORD approach?? If it isn't, is there a different frequency or something else that I am missing?

You are not listenting to Approach then. ONLY the tower clears airplanes to land on the runways. If you are at the outer marker, then you usually are on the tower frequency already.
The approach you call around 40-50NM out. Depends on the airspace structure at the airport.
Maybe you can find some frequencies for approach on the internet. I guess there are plenty. It should read "APP" for approach.

Here are some ORD approach frequencies:

119.000 133.625 128.450

That's the frequencies I could find for ORD approach.

ATIS is on 135.400.

CHICAGO APPROACH: 119.0, 133.625, 121.15, 124.35, 125.7

But if I were you, I wouldn't rely on those - there are just too many of them, and you never know which one you need to be listening to. I'd try to learn the landing patterns, and figure out which airplanes go to which runways. That way, you can call up the ATIS, see what configuration the airport is in, and then you can figure out where you need to be.

For example, if the airport is landing on 22R, 27L and 28, and you know that arrivals from the northeast that don't require a longer runway tend to go to 22R in that configuration, if you want to see a JetBlue flight from JFK, you can go camp out under the approach for 22R. This does require some trial-and-error in order to figure things out, but it's more effective in the long run.

Thanks for clarifying that, I guess I had it confused  Wink

Thanks for your advice and example underneath it. I've thought through stuff like that before, but sometimes planes land on runways that they don't usually land on, so I was hoping there was a way to find out the runway, like over the ATC frequencies, ahead of time. But I guess if I miss it, that just gives me an excuse to go back to ORD for some more spotting fun!!


Thanks to both of you for the approach frequencies, I will try those out the next time i go to ORD  Smile

My experience is that that's not generally the case at ORD. In five years of flying into ORD from the southeast continually, when the weather was nice (i.e. no snow), I can easily count on one hand the number of times I landed on something besides 4R or 28.

That's not entirely correct. The approach frequencies have particular zones. If the specific a/c he is expecting is coming from a particular direction (i.e. from Center) he will be dealing with a specific approach zone first. It would be a little work to figure out which approach frequency is where, but they rarely change after that.

Thanks again for your help with the approach frequencies guys!! I tried it out the last time I was at ORD and I was able to figure out ahead of time what runways certain planes were landing on, and it was exactly what I was looking for!  cloudnine
