{"abstract":"The FAA is proposing to amend its regulations to reflect technological advances that support area navigation (RNAV); make certain terms consistent with those of the International Civil Aviation Organization; remove the middle marker as a required component of instrument landing systems; and clarify airspace terminology. The proposed changes are intended to facilitate the transition from ground- based navigation to new reference sources, enable advancements in technology, and increase efficiency of the National Airspace System.","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/2002/12/17/02-31150.html","cfr_references":[{"chapter":null,"citation_url":null,"part":1,"title":14},{"chapter":null,"citation_url":null,"part":71,"title":14},{"chapter":null,"citation_url":null,"part":91,"title":14},{"chapter":null,"citation_url":null,"part":95,"title":14},{"chapter":null,"citation_url":null,"part":97,"title":14},{"chapter":null,"citation_url":null,"part":121,"title":14},{"chapter":null,"citation_url":null,"part":125,"title":14},{"chapter":null,"citation_url":null,"part":129,"title":14},{"chapter":null,"citation_url":null,"part":135,"title":14}],"citation":"67 FR 77326","comment_url":null,"comments_close_on":"2003-01-31","correction_of":null,"corrections":[],"dates":"Send your comments on or before January 31, 2003.","disposition_notes":null,"docket_ids":["Docket No. FAA-2002-14002","Notice No. 02-20"],"dockets":[],"document_number":"02-31150","effective_on":null,"end_page":77348,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/12/17/02-31150.xml","html_url":"https://www.federalregister.gov/documents/2002/12/17/02-31150/area-navigation-rnav-and-miscellaneous-amendments","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/02-31150?publication_date=2002-12-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-12-17/02-31150/mods.xml","not_received_for_publication":null,"page_length":23,"page_views":{"count":675,"last_updated":"2026-10-23 22:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-12-17/pdf/02-31150.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-12-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/12/17/02-31150.txt","regulation_id_number_info":{"2120-AH77":{"issue":"200404","html_url":"https://www.federalregister.gov/regulations/2120-AH77/area-navigation-rnav-and-miscellaneous-amendments","title":"Area Navigation (RNAV) and Miscellaneous Amendments","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200404&RIN=2120-AH77&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2120-AH77"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":77326,"subtype":null,"title":"Area Navigation (RNAV) and Miscellaneous Amendments","toc_doc":"Area navigation and miscellaneous amendments","toc_subject":"Air traffic operating and flight rules, etc.:","topics":["Agriculture","Air carriers","Air taxis","Air traffic control","Air transportation","Aircraft","Airmen","Airports","Airspace","Alaska","Aviation safety","Canada","Charter flights","Drug testing","Freight","Mexico","Navigation (air)","Noise control","Political candidates","Puerto Rico","Reporting and recordkeeping requirements","Safety","Smoking","Transportation","Weather"],"type":"Proposed Rule","volume":67}
