ORD "Plan Weird" And "Plan Strange"...

Fri Jun 03, 2005 11:12 am

I read a few years ago about arrival and departure runway assignments at ORD. It was in an article describing funny ATC terms and jargon (Squirrels, Flibs, Mad-dog bang right, etc.) Apparently two of the arrival/departure layouts are called "Plan Weird" and "Plan Strange". Are these the only two layouts ORD ATC uses, or are they abnormal layouts that are seldom used?

I don't know any of the specifics about what you've described. There are patterns that are very uncommon, such as arrivals on 22L, because of the long taxi to the terminals, and arrivals on 32L, which involves an intersection with 9L/27R and flying over 4R/22L about 2000 feet from the end of the runway.

It usually takes very gusty winds to get either of those runways into use for arrivals.

Plan 'weird' is the name of the arrival plan that includes arrivals on 4R and the Parallel 9R/9L with departures on 4L/9L/32L....

Plan strange I can't shed any light on....sorry...

Plan "weird" is, in fact, not very weird then as they use it a lot.

If you want to check out the various runway configurations and conditons when they are used at O'Hare, check out www.bigairport.com. Its a pretty cool website with all kinds of info on the airport. I don't think they give the name of the actual plans, but it does give the runway numbers.

There is also some good information on the FAA's OIS page.

Here's a link.. http://www.fly.faa.gov/ois/west/zau/ord/ord_aar1.htm

I have to admit, I'm a big fan of plan RODNY  Smile

RDUDDJI: Cool FAA link. Thanks. Can you or anyone else help me decifer some abbreviations and/or codes on that chart?

What is "AAR"? Is it something about arrival rates?

What is "TRIP"?

What are the meanings for these weather minimums?
700-2, 1000-3


Thanks in advance.

AAR is Aircraft Arrival Rate.

No idea what TRIP means.

700-2 means 700 ft. ceilings and 2 miles visibility
1000-3 means 1000 ft ceilings and 3 miles visibility

TRIP is the use of a third arrival runway. It will typically give an
arrival rate of 96-100 an hour depending on the configuration.
When gusty winds or wet runways preclude the use of a third
arrival runway, the rate goes to 80 (less with wet or certain
configurations) and then watch out...here come the delays.

You can use the AADC (Aircraft Arrival Demand Chart) to see what major airports are currently posting as their AAR and how many flights are scheduled.

AADC:
http://www.fly.faa.gov/Products/AADC/aadc.html

FAA's OIS (Operational Information System, shows current and planned GDP's and GS's)
http://www.fly.faa.gov/ois

That is a very useful tool to plan down the road for a GDP or GS (Ground Delay Program or Gorundstop).

There are some cool tools on the FAA's website fly.faa.gov
