Under the ADS-B drone rules, small drones flown under Part 107 are not just exempt from ADS-B Out — they are prohibited from transmitting it without specific FAA authorization. Drone identification is handled instead through Remote ID, a separate system with its own rules. ADS-B In, the receiving side, is legal and can be a useful safety tool.
The Part 107 Prohibition on ADS-B Out
The controlling rule is 14 CFR §107.53. No person may operate a small unmanned aircraft system with ADS-B Out equipment in transmit mode unless the FAA Administrator has specifically authorized the operation.1eCFR. 14 CFR Part 107 – Small Unmanned Aircraft Systems
The reason is practical. Small drones flying at low altitudes would flood air traffic control displays with targets controllers don’t need to track. A drone hovering at 200 feet near an airport, sharing a screen with a 737 on approach, creates clutter that makes the controller’s job harder. The FAA wants drone traffic managed through other systems, primarily Remote ID and LAANC authorizations.
If a waiver or special authorization requires ADS-B Out as a condition of operation, the Administrator can grant that exception. Absent that explicit permission, the transmitter stays off.
Where ADS-B Out Actually Applies
The general ADS-B Out mandate under 14 CFR §91.225 covers manned aircraft and any unmanned operations that fall outside Part 107 or receive a specific waiver into affected airspace. Those airspace categories are:
- Class A, B, and C airspace, in full.2eCFR. 14 CFR 91.225 – Automatic Dependent Surveillance-Broadcast (ADS-B) Out Equipment and Use
- Class E airspace at or above 10,000 feet MSL within the contiguous 48 states and the District of Columbia, excluding airspace at or below 2,500 feet above the surface.2eCFR. 14 CFR 91.225 – Automatic Dependent Surveillance-Broadcast (ADS-B) Out Equipment and Use
- Mode C veil areas: within 30 nautical miles of airports listed in Appendix D of Part 91, from the surface up to 10,000 feet MSL.2eCFR. 14 CFR 91.225 – Automatic Dependent Surveillance-Broadcast (ADS-B) Out Equipment and Use
For the typical Part 107 pilot flying a consumer or commercial drone under 400 feet, none of this applies. The §107.53 prohibition overrides the general rule. ADS-B Out becomes relevant only for larger unmanned aircraft operating under different regulatory frameworks or under an explicit FAA authorization.
How Part 107 Pilots Get Into Controlled Airspace
The tool is LAANC, the Low Altitude Authorization and Notification Capability. LAANC connects drone pilots to FAA-approved service suppliers through desktop and mobile apps and can deliver near-real-time airspace authorizations at pre-approved altitudes shown on UAS Facility Maps.3Federal Aviation Administration. Part 107 Airspace Authorizations
For flights at or below the ceiling on the UAS Facility Map, approval often comes back within seconds. Requests above those pre-approved altitudes but still under 400 feet go through further coordination with the local air traffic manager and must be submitted at least 72 hours in advance. LAANC requests can be submitted up to 90 days before a planned flight.3Federal Aviation Administration. Part 107 Airspace Authorizations
If you fly commercially near airports, this is the process you’ll use, and it’s the one that replaces any thought of ADS-B.
Using ADS-B In for Situational Awareness
Transmitting ADS-B Out is off-limits. Receiving it is not. A portable ADS-B In receiver picks up position broadcasts from manned aircraft and displays them on your ground station or tablet, giving you a real-time picture of traffic in your area. Many commercial drone operators treat this as standard equipment for flights near airports or along flight corridors.
The practical value is simple. You can see a manned aircraft approaching from miles away and bring your drone down or reposition well before there’s any conflict. Some setups let you define a safety bubble around your drone’s position that triggers an alert when a transmitting aircraft crosses that boundary. For infrastructure inspection along highways or powerlines, where low-flying manned aircraft are common, early warning matters.
What ADS-B In Cannot See
ADS-B In only detects aircraft that are actively transmitting ADS-B Out. Many older general aviation planes, some helicopters, ultralights, and other drones won’t appear on your receiver at all. The FAA supplements the gap with TIS-B, which rebroadcasts radar data about non-ADS-B-equipped aircraft through the ADS-B ground network. TIS-B only works for aircraft with transponders inside radar coverage, and only when an ADS-B-equipped aircraft nearby triggers the rebroadcast.4Federal Aviation Administration. Ins and Outs
Ground station coverage isn’t universal either. ADS-R, the rebroadcast service that lets aircraft on different ADS-B frequencies see each other, only works within range of a ground station.5Federal Aviation Administration. ADS-B FAQ In remote or low-altitude areas with sparse infrastructure, the traffic picture on your receiver may be incomplete. Treat ADS-B In as one layer of situational awareness. Visual observers and see-and-avoid still matter.
ADS-B Is Not Remote ID
The two systems get confused because both involve broadcasting position data. They serve different purposes.
ADS-B is an air traffic control tool. It transmits an aircraft’s position and velocity on dedicated aviation frequencies so controllers and other pilots can maintain separation. Its requirements are tied to specific controlled airspace under 14 CFR §91.225, and Part 107 drones are prohibited from using it.
Remote ID is a law enforcement and security tool. It requires drones to broadcast their identity, location, altitude, velocity, and the control station’s location using short-range signals like Wi-Fi or Bluetooth. The audience is local authorities and members of the public who can pick up the broadcast with a phone or other receiver. Nearly all registered drones must comply with Remote ID, whether flown for recreation, business, or public safety.6Federal Aviation Administration. Remote Identification of Drones
Complying with one doesn’t satisfy the other. A drone broadcasting Remote ID isn’t meeting ADS-B requirements, and an aircraft transmitting ADS-B Out isn’t meeting the Remote ID mandate. Standard Remote ID drones must broadcast the required message elements from takeoff through shutdown.7eCFR. 14 CFR 89.110 – Operation of Standard Remote Identification Unmanned Aircraft
Registration is what pulls a drone into the Remote ID system. All drones must be registered unless they weigh 0.55 pounds (250 grams) or less and are flown exclusively under the recreational exception.8Federal Aviation Administration. How to Register Your Drone The §107.53 ADS-B prohibition applies to all Part 107 operations regardless of registration.
Penalties for Getting It Wrong
Under 49 U.S.C. §46301, the maximum civil penalty for violating FAA regulations is $75,000 per violation for entities, while individuals and small business concerns face penalties of up to $10,000 per violation for safety-related offenses.9Office of the Law Revision Counsel. 49 USC 46301 – Civil Penalties
These are not theoretical figures. In early 2026, the FAA reported levying civil penalties ranging from roughly $1,800 to over $36,000 for 18 drone operations involving violations between 2023 and 2025. The agency can also suspend or revoke a pilot certificate, which for Part 107 holders means losing the ability to fly commercially. The FAA’s current enforcement posture treats legal action as the default response to UAS violations rather than a last resort.
Conduct that can draw enforcement includes flying without Remote ID, operating in controlled airspace without authorization, exceeding altitude limits, and transmitting ADS-B Out without permission under §107.53. Recreational flyers aren’t exempt from enforcement.
