{"abstract":"The FAA is revising its regulations for landing under instrument flight rules to allow aircraft to operate below certain specified altitudes during instrument approach procedures, even when the airport environment is not visible using natural vision, if the pilot uses certain FAA-certified enhanced flight vision systems. This action informs the public and the aviation industry of the approval of the use of new technology for certain operational benefits.","action":"Final rule.","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/2004/01/09/04-427.html","cfr_references":[{"chapter":null,"citation_url":null,"part":1,"title":14},{"chapter":null,"citation_url":null,"part":91,"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":135,"title":14}],"citation":"69 FR 1620","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective February 9, 2004.","disposition_notes":null,"docket_ids":["Docket No. FAA-2003-14449","Amendment Nos. 1-52","91-281","121-303","125-45","135-93"],"dockets":[],"document_number":"04-427","effective_on":"2004-02-09","end_page":1641,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2004/01/09/04-427.xml","html_url":"https://www.federalregister.gov/documents/2004/01/09/04-427/enhanced-flight-vision-systems","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/04-427?publication_date=2004-01-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2004-01-09/04-427/mods.xml","not_received_for_publication":null,"page_length":22,"page_views":{"count":603,"last_updated":"2026-07-27 10:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2004-01-09/pdf/04-427.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2004-01-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2004/01/09/04-427.txt","regulation_id_number_info":{"2120-AH78":{"issue":"200304","html_url":"https://www.federalregister.gov/regulations/2120-AH78/flight-visibility-vision-enhancing-equipment","title":"Flight Visibility; Vision Enhancing Equipment","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200304&RIN=2120-AH78&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2120-AH78"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":1620,"subtype":null,"title":"Enhanced Flight Vision Systems","toc_doc":"Enhanced flight vision systems","toc_subject":"Air traffic operating and flight rules, etc.:","topics":["Agriculture","Air carriers","Air traffic control","Air transportation","Aircraft","Airmen","Airports","Aviation safety","Charter flights","Freight","Safety","Transportation"],"type":"Rule","volume":69}
