Key Concepts

Who Must Comply and When

• Remote identification (RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace.) rules are in 14 CFRCode of Federal RegulationsCloseThe federal rulebook where Part 107, Part 89, Part 48, and other aviation rules live. part 89. After September 16, 2023, no person may operate an unmanned aircraft in U.S. airspace unless the operation meets § 89.110 (standard RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. unmanned aircraft) or § 89.115 (alternative RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. using a broadcast module), unless otherwise authorized or as provided in § 89.120.^[3]
• RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. applicability covers persons operating unmanned aircraft registered or required to be registered under parts 47 or 48, and persons operating foreign civil unmanned aircraft in the United States. Operations under part 91 transmitting ADS‑BAutomatic Dependent Surveillance-BroadcastCloseAircraft broadcast technology. Part 107 drones generally may not use ADS-B Out unless specifically authorized. Out pursuant to § 91.225 are excluded from subpart B.^[3]
• Most small unmanned aircraft that are registered or required to be registered must comply with RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. after September 16, 2023. The serial number of a standard RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. unmanned aircraft, or the serial number of the installed broadcast module, must be listed on the Certificate of Aircraft Registration and may be listed on only one certificate at a time. A broadcast module may be moved between aircraft, but its serial number must also be moved on the registration before flight. Small unmanned aircraft not required to be registered under part 48, such as those weighing 0.55 pounds or less, must comply with RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. when operated under any operating part for which registration is required. RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. provides location and identification data to the FAAFederal Aviation AdministrationCloseThe U.S. aviation regulator responsible for Part 107 rules, airspace, and pilot certification processes., national security agencies, and law enforcement to distinguish compliant users.^[2]

Standard RID Unmanned Aircraft: What Must Be Broadcast

A standard RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. unmanned aircraft must broadcast the following message elements:

• Identity (either the aircraft serial number assigned by the producer or a session ID)
• Latitude/longitude and geometric altitude of the control station
• Latitude/longitude and geometric altitude of the unmanned aircraft
• Velocity of the unmanned aircraft
• UTC time mark
• Emergency status of the unmanned aircraft^[4]

Minimum performance requirements include:

• Control station location encoded in the message must correspond to the location of the person manipulating the flight controls
• Time mark synchronized with all other RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. message elements
• Self‑testing and monitoring, including prior to takeoff^[5]

Practical takeaway: For standard RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. aircraft, the control station location must reflect the actual position of the person manipulating the controls, and the system must continuously monitor its RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. function.

Broadcast Modules and Alternative RID Operations

If the aircraft is not a standard RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. aircraft, you may comply by using a remote ID broadcast module if all conditions of § 89.115(a) are met:

• Equipage/administration: The aircraft must be equipped with a broadcast module meeting § 89.320, listed on an FAAFederal Aviation AdministrationCloseThe U.S. aviation regulator responsible for Part 107 rules, airspace, and pilot certification processes.‑accepted declaration of compliance; the aircraft’s registration must include the module’s serial number, or the aircraft serial number must be provided to the FAAFederal Aviation AdministrationCloseThe U.S. aviation regulator responsible for Part 107 rules, airspace, and pilot certification processes. in a notice of identification under § 89.130 prior to operation.^[8]
• Operating requirements: From takeoff to shutdown, you must ensure the module broadcasts all message elements in § 89.315 directly from the aircraft, and the person manipulating the controls must be able to see the aircraft at all times throughout the operation.^[8]

Broadcast module message elements include:

• Module serial number (identity)
• Latitude/longitude and geometric altitude of the unmanned aircraft
• Velocity of the unmanned aircraft
• Latitude/longitude and geometric altitude of the takeoff location
• UTC time mark^[6]

Module performance requirements include:

• Capability to determine takeoff location
• Time mark synchronized with other message elements
• Automatic preflight self‑test with notification of results; continuous monitoring from takeoff to shutdown with malfunction notifications
• Tamper resistance^[7]

Practical takeaway: Module-based RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. requires continuous broadcast from takeoff to shutdown and imposes a strict “see the aircraft at all times” requirement on the person manipulating the controls.

Registration and Pilot Responsibility

• RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. compliance, serial‑number linkage on the registration, and any updates when moving a module between aircraft are operational responsibilities under part 107 guidance.^[2]
• As with all small UASSmall Unmanned Aircraft SystemCloseA small drone plus the control and communication links used to operate it. operations, the remote pilot in command is directly responsible for, and the final authority on, the safe operation of the aircraft—this includes ensuring RIDRemote IdentificationCloseRemote ID broadcast requirements for most drones operating in U.S. airspace. requirements are satisfied before flight.^[1]
