The FAA describes one acceptable manner producers of unmanned plane can meet the minimal efficiency requirement for the accuracy of the management station's reported geometric altitude. The FAA decided that this motion is important to tell builders of technique of compliance of one potential pathway to fulfill the efficiency requirement for the management station's reported geometric altitude. DATES: The efficient date of this coverage is November 22, 2021. ADDRESSES: For info on the place to acquire copies of this assertion of coverage and different info associated to this assertion, see ``Further Data'' within the SUPPLEMENTARY INFORMATION part of this doc. FOR FURTHER INFORMATION CONTACT: Paul Siegmund, Coverage and Innovation Division, Federal Aviation Administration, 800 Independence Ave. SW, Washington, DC 20591; phone 1-844-FLY-MY-UA (1-844-359-6981); e-mail: [email protected] SUPPLEMENTARY INFORMATION: I. Overview A. Background On January 15, 2021, the FAA revealed a last rule titled ``Distant Identification of Unmanned Plane'' (Distant ID last rule) with an unique efficient date of March 16, 2021.1 2 The Distant ID last rule requires the distant identification of unmanned plane within the airspace of the USA. Distant identification is the aptitude of an unmanned plane, in flight, to offer sure identification, location, and efficiency info that folks on the bottom and different airspace customers can obtain. --------------------------------------------------------------------------- 1 Distant Identification of Unmanned Plane last rule, 86 FR 4390 (Jan. 15, 2021). 2 On March 10, 2021, the FAA revealed a correction to the Distant ID last rule in accordance with the memorandum titled Regulatory Freeze Pending Evaluation (86 FR 7424, Jan 28, 2021), delaying the ultimate rule's efficient date to April 21, 2021 (86 FR 13629). --------------------------------------------------------------------------- Along with the working necessities, the Distant ID last rule supplies the design and manufacturing necessities for the manufacturing of distant identification unmanned plane or broadcast modules. These necessities describe the efficiency requirements for distant identification with out establishing a particular means or course of for regulated entities to observe.3 An individual designing or producing a normal distant identification unmanned plane or distant identification broadcast module should present that the unmanned plane or broadcast module meets the efficiency necessities of the rule by following an FAA-accepted technique of compliance. A way of compliance submitted to the FAA for acceptance should present that an unmanned plane or broadcast module produced utilizing it might meet the efficiency necessities of title 14 of the Code of Federal Laws half 89 (14 CFR half 89). This coverage assertion solely addresses the efficiency necessities and compliance path for the normal distant identification unmanned plane. --------------------------------------------------------------------------- 3 A typical distant identification unmanned plane broadcasts identification, location, and efficiency info of the unmanned plane and management station. This unmanned plane broadcasts the distant identification message parts straight from theunmanned plane from takeoff to shutdown. A distant identification broadcast module broadcasts identification, location, and take-off info; the printed module could also be a separate machine that's hooked up to an unmanned plane, or a function constructed into the plane. 86 FR 4391 (Jan. 15, 2021). --------------------------------------------------------------------------- Half 89 requires the next 8 message parts to be broadcast from a typical distant identification unmanned plane: (1) Unmanned plane distinctive identifier; (2) a sign of the management station's latitude and longitude; (3) a sign of the management station's altitude; (4) a sign of the unmanned plane's latitude and longitude; (5) a sign of the unmanned plane's altitude; (6) a time mark; (7) a sign of the emergency standing of the unmanned plane system; and (8) velocity. Moreover, all normal distant identification unmanned plane should meet sure minimal necessities concerning the transmission of the message parts together with the minimal efficiency necessities associated to positional accuracy, geometric altitude accuracy, message latency, and message transmission charge. These minimal efficiency necessities for the message parts are design necessities; any particular check technique for making certain that the unmanned plane design meets this accuracy requirement will likely be reviewed and evaluated by the FAA as part of the technique of compliance acceptance course of. Half 89 establishes the accuracy requirement for the reported geometric altitude for the management station of a typical distant identification unmanned plane. Particularly, Sec. 89.310(h)(2) requires that the reported geometric altitude of the management station should be correct to inside 15 toes of the true geometric altitude, with 95 % chance. The Distant ID last rule didn't specify how a technique of compliance ought to deal with this requirement. As a way to information producers to develop normal distant identification unmanned plane that meet the FAA's requirements, this coverage assertion informs builders of 1 potential technique of compliance that will be acceptable to the FAA to show compliance with assembly the geometric altitude requirement. Individuals creating a way of compliance for the standard distant identification unmanned plane in accordance with 14 CFR half 89, subpart E, might incorporate the strategy described on this coverage assertion as a part of their technique of compliance. The FAA emphasizes, nevertheless, that different methods of demonstrating compliance with Sec. 89.310(h)(2) could also be acceptable. B. Assertion of Coverage: Acceptable Technique This assertion of coverage describes one acceptable manner, however not the solely manner, that the accuracy necessities for the reported geometric altitude of the management station of a typical distant identification unmanned plane can meet the minimal efficiency requirement in Sec. 89.310(h)(2). The FAA is just not requiring builders of technique of compliance to incorporate the precise technique supplied on this assertion of coverage. A way of compliance that requires the unmanned plane system (UAS) management station place supply to be a worldwide navigation satellite tv for pc system (GNSS) receiver using International Positioning System (GPS) and Extensive Space Augmentation System (WAAS) satellite tv for pc alerts to decide the geometric altitude of the management station can be an acceptable technique for a way of compliance to show that the unmanned plane constructed in keeping with its specs would meet the accuracy requirement in Sec. 89.310(h)(2). The WAAS Efficiency Evaluation report from the second quarter of 2021 exhibits that GNSS receivers using GPS with a satellite-based augmentation system signifies a worst-site 95% vertical accuracy of 5 toes for the continental United States.4 This report demonstrates that GNSS receivers using GPS/WAAS can obtain the required vertical place accuracy throughout the Nationwide Airspace System to fulfill the reported geometric altitude requirement of Sec. 89.310(h)(2). --------------------------------------------------------------------------- 4 https://www.nstb.tc.faa.gov/DisplayArchive.htm. --------------------------------------------------------------------------- The FAA acknowledges that UAS expertise, which incorporates distant identification expertise, is regularly evolving and bettering. Accordingly, the FAA expects that different strategies could also be out there to meet this requirement aside from the one talked about on this coverage assertion, and nothing about this assertion ought to preclude builders of technique of compliance from together with different technological strategies of assembly the vertical accuracy necessities for the reported geometric altitude of the management station. This assertion of coverage solely addresses one technique of demonstrating compliance with Sec. 89.310(h)(2); be aware that any technique of compliance submitted to the FAA should additionally adequately deal with the opposite necessities partially 89, subparts D and E, to be able to be accepted by the FAA.
