Movements On Runway 27R At ORD

Sat Aug 11, 2012 3:54 am

It seems very few heavies use RWY27R at O'Hare; is there a reason for this? When the winds are westerly, widebodies can regularly be seen landing on RWY28 and RWY27L but almost none on 27R. Lengthwise, there is no major difference between the 27s - is it because of the longer taxi times associated with 27R?

Also, is 9L/27R used for departures?

There have been times they've used 27R for heavies but to my knowledge there's no specific reason against not using it.

As for taxi times, for 27R arrivals, once you clear the runway, it's about 10 to reach UA, 15 to reach AA and 20 to reach International.

I have never witnessed a departure from 9L, so I'm going to call upstairs and ask the guys would or have they.

On a side note, they have relocated Signature Flight Support which was needed to start 27C runway.

A captain I flew with last week has a running app on his phone and just out of curiosity he turned it on just as we were taking the high-speed off 27R. From there to the G concourse it is 4.2 miles and took 16 minutes. Not a fan of landing 27R.

If you listen to liveATC you will hear most of the heavies request runway 10/28 with the center before being handed off to approach. Any that get 27R will typically say "unable 27R, request 28." 27R is the runway usually assigned to flights arriving from the NW or NE (ie. transatlantic) on the WYNDE or BULLZ arrivals. I would think they barely have the required performance for a landing on 27R, but coupled with crew fatigue, 10/28 is a much safer option, and I've never heard ATC not give it to them. UAL and AA are the only heavies I've seen land on 27R and a 767 is the largest I have seen. All the international carriers end up with 28. Many of them take 22R though, when assigned, so I imagine the margins are close for 27R.

I've heard them get denied 28 before. It was actually pretty funny, British checked on and asked for 28 and the controller came back on and just said "no" and moved on to another plane. I see heavies use 4R and the 14s fairly often as well, but with O'Hare it's hard telling what they'll use on a given day with all those runways.

Quoting loggat (Reply 3):

It's interesting they would take 22R but not 27R, correct me if I'm wrong but I thought both were 7500ft by 150ft?

I landed 27R a few months back to taxi to the GA/Cargo ramp. The taxi route was ridiculously long (over 15mins) via the west side and then back across the airline ramp. I queried the controller about this route and he explained the procedure is for taxiing aircraft to cross as few runways as possible...therefore the circuitous route.

Since then I always hope to avoid landing on 27R but it's not up to me....unfortunately.

If its a hassle for me it's likely a hassle for ATC too.

Thanks for the replies all, very interesting! The 767 is the largest I've seen landing on 27R in recent times. Also saw an EI A330 back in 2010 though.

I would imagine it has more to do with the turn off. Even in a 170 the turn from the runway to the parallel taxiway is pretty sharp. It's also a shorter runway, with a long taxi. Hot brakes could be a major issue on a heavy jet.
