{"abstract":"This action raises the upper limit of Restricted Areas 6904A (R-6904A) and R-6904B, Volk Field, WI, from 17,000 feet above mean sea level (MSL) to Flight Level 230 (FL 230). Expanding the vertical limit of these areas facilitates the transition of participating aircraft between these restricted areas and the overlying Volk West Air Traffic Control Assigned Airspace (ATCAA). The additional airspace is needed to fulfill new United States Air Force (USAF) training requirements. This rule makes no other changes to R-6904A or R-6904B.","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/2003/04/23/03-10043.html","cfr_references":[{"chapter":null,"citation_url":null,"part":73,"title":14}],"citation":"68 FR 19946","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"0901 UTC, July 10, 2003.","disposition_notes":null,"docket_ids":["Docket No. FAA-2002-13414","Airspace Docket No. 02-AGL-7"],"dockets":[],"document_number":"03-10043","effective_on":null,"end_page":19947,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/04/23/03-10043.xml","html_url":"https://www.federalregister.gov/documents/2003/04/23/03-10043/modification-of-restricted-areas-r-6904a-and-r-6904b-volk-field-wi","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-10043?publication_date=2003-04-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-04-23/03-10043/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":395,"last_updated":"2026-06-05 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-04-23/pdf/03-10043.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-04-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/04/23/03-10043.txt","regulation_id_number_info":{"2120-AA66":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA66/airspace-actions","title":"Airspace Actions","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA66&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA66"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":19946,"subtype":null,"title":"Modification of Restricted Areas R-6904A and R-6904B, Volk Field, WI","toc_doc":"Restricted areas","toc_subject":null,"topics":["Airspace","Navigation (air)"],"type":"Rule","volume":68}
