{"abstract":"This action clarifies FAA policy regarding the existing accuracy requirements for the reported geometric altitude of the control station of a standard remote identification unmanned aircraft. The FAA describes one acceptable way producers of unmanned aircraft can meet the minimum performance requirement for the accuracy of the control station's reported geometric altitude. The FAA determined that this action is necessary to inform developers of means of compliance of one potential pathway to meet the performance requirement for the control station's reported geometric altitude.","action":"Statement of policy.","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/2021/11/22/2021-25366.html","cfr_references":[{"chapter":null,"citation_url":null,"part":89,"title":14}],"citation":"86 FR 66162","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this policy is November 22, 2021.","disposition_notes":null,"docket_ids":["Docket No.: FAA-2019-1100"],"dockets":[],"document_number":"2021-25366","effective_on":"2021-11-22","end_page":66163,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/11/22/2021-25366.xml","html_url":"https://www.federalregister.gov/documents/2021/11/22/2021-25366/policy-statement-for-the-reported-geometric-altitude-of-the-control-station-of-a-standard-remote","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-25366?publication_date=2021-11-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-11-22/2021-25366/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":727,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-11-22/pdf/2021-25366.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-25366.pdf?1637329529","publication_date":"2021-11-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/11/22/2021-25366.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"EO 12866 - Meeting Race Day Quads","document_id":"FAA-2019-1100-53285"},{"title":"EO 12866 Meeting - News Media Coalition","document_id":"FAA-2019-1100-53283"},{"title":"EO 12866 Meeting - FIRST iZ","document_id":"FAA-2019-1100-53281"},{"title":"EO 12866 Meeting - Drone Racing League","document_id":"FAA-2019-1100-53280"},{"title":"EO 12866 Meeting - Dedrone","document_id":"FAA-2019-1100-53278"},{"title":"EO 12866 Meeting - Consumer Technology Industry Association","document_id":"FAA-2019-1100-53277"},{"title":"EO 12866 Meeting - Airlines for America","document_id":"FAA-2019-1100-53273"},{"title":"Privacy Impact Assessment for Remote Identification of Unmanned  Aircraft - Final Rule","document_id":"FAA-2019-1100-53269"},{"title":"Advisory Circular 89-2  - Declaration of Compliance Process for  Remote Identification of Unmanned Aircraft","document_id":"FAA-2019-1100-53268"},{"title":"Advisory Circular 89-1  - Means of Compliance Process for Remote  Identification of Unmanned Aircraft","document_id":"FAA-2019-1100-53267"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AL31/remote-identification-of-unmanned-aircraft-systems","title":"Remote Identification of Unmanned Aircraft Systems"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2019-1100","supporting_documents_count":60,"docket_id":"FAA-2019-1100","document_id":"FAA-2019-1100-53294","regulation_id_number":"2120-AL31","title":"Remote Identification of Unmanned Aircraft Systems ","checked_regulationsdotgov_at":"2021-11-23T04:30:10Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":66162,"subtype":null,"title":"Policy Statement for the Reported Geometric Altitude of the Control Station of a Standard Remote Identification Unmanned Aircraft","toc_doc":"Policy Statement for the Reported Geometric Altitude of the Control Station of a Standard Remote Identification Unmanned Aircraft","toc_subject":null,"topics":[],"type":"Rule","volume":86}
