{"abstract":"This action proposes to modify RNAV route T-265 in support of the O'Hare Modernization Project (OMP)/Chicago Airspace Project (CAP). This proposed action would insert a dogleg and re-align T-265 slightly to the west to provide appropriate lateral spacing from a new Rockford Airport Traffic Control Tower (RFD) and Chicago Terminal Radar Approach Control (C90) airspace boundary and to maintain the efficiency and safety of aircraft transitioning around the Chicago Class B airspace area.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2013/12/26/2013-30693.html","cfr_references":[{"chapter":null,"citation_url":null,"part":71,"title":14}],"citation":"78 FR 78303","comment_url":null,"comments_close_on":"2014-02-10","correction_of":null,"corrections":[],"dates":"Comments must be received on or before February 10, 2014.","disposition_notes":null,"docket_ids":["Docket No. FAA-2013-0952","Airspace Docket No. 13-AGL-18"],"dockets":[],"document_number":"2013-30693","effective_on":null,"end_page":78305,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/12/26/2013-30693.xml","html_url":"https://www.federalregister.gov/documents/2013/12/26/2013-30693/proposed-modification-of-area-navigation-rnav-route-t-265-il","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-30693?publication_date=2013-12-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-12-26/2013-30693/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":76,"last_updated":"2026-08-24 14:15:12 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-12-26/pdf/2013-30693.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-30693.pdf?1387892928","publication_date":"2013-12-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/12/26/2013-30693.txt","regulation_id_number_info":{"2120-AA66":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA66/airspace-actions","title":"Airspace Actions","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA66&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA66"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2014-02-19T05:07:43Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":78303,"subtype":null,"title":"Proposed Modification of Area Navigation (RNAV) Route T-265, IL","toc_doc":"Modification of Area Navigation (RNAV) Route T-265, IL","toc_subject":null,"topics":["Airspace","Incorporation by reference","Navigation (air)"],"type":"Proposed Rule","volume":78}
