# Disclaimer of Warranty, Liability, and Fitness for Use **ADSBin — Copyright 2026 D Everett Hinton — Novabox.Works (https://novabox.works/)** > **READ THIS BEFORE BUILDING, INSTALLING, OR OPERATING ADSBIN.** > > This disclaimer is in addition to, and not in place of, the warranty and > liability terms of the [PolyForm Noncommercial License 1.0.0](LICENSE.md) under > which the software, firmware, hardware designs, documentation, and all related > files (collectively, the **"Project"**) are made available. Choosing, > purchasing, building, flashing, installing, or operating any part of the Project, > or any device incorporating it, constitutes your acceptance of this disclaimer in > full. If you do not accept it, do not use the Project. --- ## 1. Experimental and Advisory Use Only The Project is an **experimental, advisory traffic-awareness aid** intended solely for use in **amateur-built / experimental category aircraft** by qualified persons who accept full responsibility for its use. It is a **receive-only** device that listens for ADS-B (and, in later configurations, UAT) broadcasts from *some* nearby aircraft and presents their approximate, supplementary positions to a separate display. The Project is **NOT** a flight instrument, **NOT** a navigation system, **NOT** a collision-avoidance system, **NOT** a TCAS / ACAS / TAS / TCAD or any other traffic advisory or resolution system, **NOT** a substitute for air traffic control, and **NOT** a substitute for the pilot's see-and-avoid responsibility. It is **advisory only**. Its outputs are convenience cues and nothing more. ## 2. Receive-Only — Not ADS-B Out — No Equipage Credit The Project is **receive-only ("ADS-B In")**. It **does not transmit**, it does **not** make your aircraft visible to ATC or to any other aircraft, and it does **NOT** satisfy any ADS-B Out equipage requirement or mandate (including, without limitation, 14 CFR §§ 91.225 / 91.227 or any equivalent rule in your jurisdiction). Do not treat the presence of this device as meeting any equipment requirement of any kind. ## 3. Not Certified — No Airworthiness Approval The Project is **NOT** certified, approved, qualified, or authorized by the Federal Aviation Administration (FAA), the European Union Aviation Safety Agency (EASA), or any other civil aviation authority, regulatory body, or standards organization. It has **not** been developed, tested, or documented in accordance with any aviation software, hardware, environmental, or design-assurance standard (including, without limitation, DO-178C, DO-254, DO-160, DO-260, DO-282, TSO, ETSO, or any AC/AMC guidance). No representation is made that the Project complies with any airworthiness requirement. Installation or operation of the Project in any aircraft may be subject to regulation in your jurisdiction, and **you alone** are responsible for determining and ensuring compliance with all applicable laws, regulations, operating limitations, and the airworthiness requirements governing your aircraft. Installation in type-certificated aircraft is **not** intended or supported. ## 4. No Warranty of Any Kind **TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE PROJECT IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OR CONDITION OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.** The licensor and any contributors expressly disclaim all warranties and conditions, including, without limitation, any implied warranties or conditions of **merchantability, satisfactory quality, fitness for a particular purpose, accuracy, reliability, availability, title, and non-infringement**, and any warranties arising out of course of dealing, course of performance, usage, or trade practice. Without limiting the foregoing, **no warranty is made** that the Project will meet your requirements; that it will be accurate, timely, complete, uninterrupted, secure, or error-free; that any traffic target, position, altitude, or other output will be correct, present, complete, or on time; or that defects will be corrected. **A wrong, missing, late, ghost, or misleading target may occur at any time and without warning, and aircraft may be entirely absent from the display.** You assume the entire risk as to the quality, performance, accuracy, completeness, and timeliness of the Project and any device built from it. ## 5. Limitation and Exclusion of Liability **TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE LICENSOR, THE AUTHOR(S), NOVABOX.WORKS, OR ANY CONTRIBUTOR, SUPPLIER, OR DISTRIBUTOR BE LIABLE TO YOU OR TO ANY THIRD PARTY FOR ANY DAMAGES OF ANY KIND** arising out of or in any way related to the Project or its use, inability to use, installation, operation, or performance — including, without limitation, any **direct, indirect, incidental, special, exemplary, punitive, or consequential damages**; loss of life, personal injury, or bodily harm; property damage, including damage to or loss of any aircraft; mid-air collision or loss of separation; loss of use, loss of data, loss of profits, business interruption, or cost of substitute goods or services — **whether based in contract, warranty, tort (including negligence), strict liability, product liability, or any other legal or equitable theory, and whether or not the licensor has been advised of, or could have foreseen, the possibility of such damages, and even if any remedy is found to have failed of its essential purpose.** Where applicable law does not permit the exclusion or limitation of certain damages or of implied warranties, the disclaimers and limitations in this document shall apply to the **fullest extent permitted by that law**, and the licensor's aggregate liability shall be limited to the **greater of the amount you paid (if any) for the specific copy of the Project giving rise to the claim, or zero**. ## 6. No Substitute for See-and-Avoid and Pilot Judgment The Project is **never** a substitute for the pilot's **continuous outside visual scan and see-and-avoid responsibility**, for air traffic control services, for properly installed and approved traffic systems, for established procedures, for adequate training and currency, or for the pilot's own situational awareness — most especially in the traffic pattern, during taxi, takeoff, and approach, and in busy or non-towered airspace. **Do not maneuver, and do not fail to maneuver, on the basis of an ADSBin display.** Treat every target — and every *apparently empty* piece of sky — as unverified, supplementary information that may be wrong, incomplete, or absent. The pilot in command is at all times solely responsible for traffic separation and the safe operation of the aircraft and must be fully prepared to operate safely with **no reliance whatsoever** on the Project. ## 7. Inherent ADS-B and Operational Limitations The Project shows only what it can receive and decode, and is subject to inherent and unavoidable limitations, including, without limitation: - **It cannot see non-cooperative traffic.** Aircraft without ADS-B Out, with it switched off or inoperative, military or other exempt aircraft, gliders, balloons, birds, drones, and obstacles may be **completely invisible**. There is **no primary radar** in this device. - **TIS-B / ADS-R rebroadcast traffic** depends on ground-station coverage and on a suitably equipped nearby client; it may be partial, delayed, or absent, and may show duplicate or "ghost" targets. - **Reception is imperfect:** dropped, late, or garbled messages; antenna shadowing during maneuvering; range, terrain, and line-of-sight limits; interference and a raised noise floor; CPR/decoding ambiguity or error; and **position latency** mean a target's shown position may lag or differ from reality. - **Configuration and environment:** range/altitude filtering, single-band operation (1090-only configurations do not see UAT-only traffic, and vice-versa), mounting, antenna, installation, or configuration error; electrical noise, brown-out, reboot, or power interruption; and software defects. Under any of these conditions the Project may report nothing, omit real aircraft, or report incorrectly, **without warning**. ## 8. Assumption of Risk and Indemnification **You knowingly and voluntarily assume all risks** associated with building, installing, operating, and relying on the Project. **Aviation is inherently dangerous; experimental aircraft and experimental avionics compound that risk.** You represent that you are qualified to make your own independent assessment of the Project's suitability for your intended use. To the maximum extent permitted by applicable law, you agree to **indemnify, defend, and hold harmless** the licensor, the author(s), Novabox.Works, and all contributors, suppliers, and distributors from and against any and all claims, demands, suits, actions, losses, liabilities, damages, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your use, installation, distribution, or operation of the Project, or any device incorporating it, or your breach of this disclaimer or the [License](LICENSE.md). ## 9. Relationship to the License; Severability This disclaimer supplements the **[PolyForm Noncommercial License 1.0.0](LICENSE.md)**. In the event of any conflict between this disclaimer and that license with respect to warranty or liability, the broadest disclaimer and the greatest limitation of liability permitted by applicable law shall control. If any provision of this disclaimer is held to be unenforceable or invalid, that provision shall be modified or severed to the minimum extent necessary, and the remaining provisions shall remain in full force and effect. --- *By using ADSBin you acknowledge that you have read, understood, and agree to this Disclaimer of Warranty, Liability, and Fitness for Use, and to the [PolyForm Noncommercial License 1.0.0](LICENSE.md).*
