Since the commissioning of Runway 9L/27R at O'Hare in November 2008, the FAA has received numerous questions regarding the O'Hare Modernization Program. In a continuing effort to provide information to the community, FAA will be posting the questions and FAA's responses on this web site. If the questions posed are outside FAA's jurisdiction we will forward them, as appropriate, to the O'Hare Noise Compatibility Commission (ONCC) or the City of Chicago. You may submit your questions at CMP@FAA.GOV
