Terms of Use and Database License Agreement

480Data, LLC · Last updated September 28, 2026

This Terms of Use and Database License Agreement (the “Agreement”) is a legal agreement between you and 480Data, LLC (“480Data,” “we,” “us” or “our”). It governs your use of the 480data.com web site, your account, the navigation databases we offer (the “Databases”), the GNS 480 Card Utility (the “Card Utility”) and the 480 Trainer (together, the “Service”). Section 4 is the end user license agreement for the Databases.

Please read this Agreement carefully. It limits how and where you may use the Databases, disclaims warranties, limits our liability, requires you to bring claims individually and not as part of a class, and provides that North Carolina law governs. By creating an account, subscribing, checking the box that says you agree, or downloading, installing or using any Database, the Card Utility or the Trainer, you agree to this Agreement. If you do not agree, do not use the Service.

1. Important safety warning

The warning at the top of this page is part of this Agreement. In particular: the Databases are built from publicly available FAA data and are not certified navigation data. They are licensed only for use with CNX80 and GNS 480 installations placarded “GPS LIMITED TO VFR USE ONLY” as required by the GNS 480 (CNX80) Installation Manual, 560‑0982‑01 Rev. G, page 2‑2, and only to enhance situational awareness and for practice approaches in visual conditions. Do not use them for navigation, under instrument flight rules, or in instrument meteorological conditions. Use is entirely at your own risk.

2. Definitions

Authorized Installation: A CNX80 or GNS 480 unit installed in an aircraft and placarded “GPS LIMITED TO VFR USE ONLY” as required by the GNS 480 (CNX80) Installation Manual, 560‑0982‑01 Rev. G, page 2‑2.
Authorized Aircraft: The one aircraft, identified by its registration number, in which you use the Databases under your subscription (Section 4.2).
Cycle: A Database edition for one FAA 28-day aeronautical information cycle, with the effective and expiration dates shown in your account and in the Card Utility.
Databases: The navigation databases we make available through the Service, each Cycle of them, and any part, copy or derivative of them, in any format.
Subscription: Your paid annual subscription to the Service (Section 9).

3. Eligibility and accounts

3.1 You must be at least 18 years old and able to enter into a binding contract. If you accept this Agreement for a company, flying club, school or other organization, you represent that you have authority to bind it, and “you” includes that organization.

3.2 You must give accurate account information and keep it current. You are responsible for keeping your sign-in credentials secret and for everything done through your account. An account is for one person or organization and may not be shared. Tell us promptly at support@480data.com if you believe your account has been used without your permission.

4. Database license

4.1 Grant. Subject to this Agreement and to payment of your Subscription, 480Data grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download each Cycle made available to your account during your Subscription and to install and use it only on the Authorized Installations in the Authorized Aircraft, only within the operating limitations in Section 5.

4.2 One aircraft. A Subscription covers one Authorized Aircraft. You may install the same Cycle on every Authorized Installation in that aircraft. If you sell or stop operating the Authorized Aircraft, you may move your Subscription to a replacement aircraft by telling us; you must then remove the Databases from the units in the former aircraft, unless the new owner has a Subscription of his own. Using the Databases in more than one aircraft requires a Subscription for each.

4.3 Copies. You may keep the files you download, the data cards you write with the Card Utility, and one backup copy, all solely to install the Databases on the Authorized Installations. Each copy must keep all notices that we include.

4.4 Cycles you have downloaded. Your license to a Cycle you downloaded while your Subscription was active continues after your Subscription ends, subject to this Agreement, unless this Agreement is terminated for your breach (Section 17). An expired Cycle is out of date: see Section 7.3.

4.5 Reservation. The Databases are licensed, not sold. We reserve every right not expressly granted to you.

5. Operating limitations

You agree that you, and anyone who flies the Authorized Aircraft, will observe all of the following. It is your responsibility to make sure that every pilot who may use the Databases knows of these limitations.

VFR only. The Databases may be used only under visual flight rules and in visual meteorological conditions, and only in an Authorized Installation. You must not use them for navigation under instrument flight rules, in instrument meteorological conditions, or to satisfy any requirement for navigation equipment, instrument currency or proficiency, or any other regulatory requirement.
Supplemental use only. The Databases may be used only to enhance situational awareness. They are not a substitute for current FAA charts, the Chart Supplement, NOTAMs, a proper preflight briefing, or visual reference to the ground, terrain, obstacles and other traffic.
Practice approaches. Instrument approach procedures in the Databases may be flown only as practice in visual meteorological conditions. When the pilot flying uses a view-limiting device, a safety pilot meeting the requirements of 14 CFR 91.109 must occupy the other control seat. Practice approaches flown with the Databases do not count toward instrument experience or currency.
Installation and placard. You are solely responsible for the installation, airworthiness and approval of your aircraft and its equipment, including the placard required by the installation manual. 480Data does not install, inspect or approve equipment and does not supply placards.
Pilot in command. Nothing in this Agreement or the Service changes the pilot in command’s responsibility and final authority for the operation of the aircraft (14 CFR 91.3) or the duty to become familiar with all available information concerning each flight (14 CFR 91.103).
Not included. The Databases do not contain NOTAMs, temporary flight restrictions, terrain or obstacle data, and may not contain every airspace area, procedure, airport or facility. The absence of an item from the Databases does not mean it does not exist.

6. Restrictions

Except as this Agreement expressly allows, you must not, and must not let anyone else:

copy, distribute, publish, sell, rent, lease, lend, share, sublicense or transfer any Database, or make it available to anyone else, including over a network or file-sharing service;
use any Database in any aircraft other than the Authorized Aircraft, in any unit that is not an Authorized Installation, or in any other device, software, application or service;
modify, translate, merge or create derivative works of any Database, or extract, re-arrange or re-encode its data for use elsewhere;
decompile, disassemble or reverse engineer any Database, its format or the Card Utility, except to the extent applicable law expressly permits this despite this restriction;
remove, alter or obscure any notice, label, date or warning in the Databases, the Card Utility or the Service;
get around, or try to get around, download limits, authentication or other technical measures, or access the Service by automated means other than the Card Utility;
use the Service in violation of any law, including export control and sanctions laws.

Nothing in this Agreement restricts your use of FAA data that you obtain directly from the FAA or from any source other than 480Data.

7. Source data, accuracy and currency

7.1 Source. The Databases are compiled from data published by the Federal Aviation Administration, including the Coded Instrument Flight Procedures (CIFP) and the 28-day National Airspace System Resources (NASR) subscription. The FAA does not produce, review, approve or endorse the Databases.

7.2 Errors. The source data may contain errors and omissions, and converting it into the format your unit reads may introduce others. We check each Cycle before we publish it, but we do not verify every item and we do not promise that any Database is complete, accurate or correctly displayed by your unit. Always verify the Database against current official FAA publications. Please report errors you find to support@480data.com.

7.3 Currency. Each Cycle is effective only between the dates stated for it. Do not use a Cycle outside those dates. Aeronautical information changes between Cycles; changes published by NOTAM or otherwise between Cycles are not reflected in the Databases.

8. Ownership and trademarks

8.1 The Databases, including the selection, arrangement, coding, format and presentation of their data, are copyrighted by 480Data, LLC and are protected by copyright and other laws. The Card Utility, the Trainer and the rest of the Service are owned by 480Data, LLC or its licensors. The underlying FAA data is a work of the United States Government; 480Data claims no copyright in it.

8.2 Garmin, GNS, Apollo and CNX80 are trademarks of Garmin Ltd. or its subsidiaries. Other names are trademarks of their owners. They are used on the Service only to describe compatibility. 480Data is not affiliated with or approved by Garmin, LLC or affiliated companies.

8.3 If you send us suggestions or error reports, you allow us to use them for any purpose without obligation to you.

9. Subscription, billing, renewal and cancellation

9.1 Annual subscription. Access to the Databases requires a paid Subscription. The price and billing terms are shown before you subscribe. Payments are processed by our payment processor, Stripe; we do not receive or store your full card number. Prices do not include taxes, which you pay where applicable.

9.2 Automatic renewal. Your Subscription renews automatically for successive one-year terms, and we will charge the payment method on file at the start of each term at the then-current price, until you cancel. We will email you a reminder before each renewal. If the price is going to change, we will tell you at least 30 days before the renewal at which it takes effect.

9.3 Cancellation. You may cancel at any time from your account page (“Manage billing / cancel”) or by emailing support@480data.com. Cancellation stops the next renewal. Your Subscription remains active, and you may continue to download Cycles, until the end of the term you have paid for.

9.4 No refunds. Payments are non-refundable, and we do not give refunds or credits for partial terms or unused Cycles, except as Section 17.2 provides or where the law requires otherwise.

9.5 Failed payments. If a payment fails, we may suspend downloads until it is made, and we may end the Subscription if it is not made within a reasonable time.

10. Downloads

While your Subscription is active, each Cycle may be downloaded once per account, with the Card Utility. If a download is interrupted, it may be downloaded again within 24 hours of the first download. We may, at our discretion, help if a download is lost; write to support@480data.com. We normally publish each Cycle before it takes effect, but we do not guarantee when or whether any Cycle will be available, and we may withhold a Cycle that does not pass our checks.

11. Card Utility

11.1 We grant you a limited, non-exclusive, non-transferable, revocable license to install and use the Card Utility on computers you own or control, solely to obtain Databases under this Agreement and write them to data cards for the Authorized Installations. Sections 6 and 8 apply to it.

11.2 The Card Utility writes to the data card you choose and replaces what is on it. Keep a copy of anything on the card you want to keep. You are responsible for choosing the right card and drive, and for using a card and card reader suitable for your unit.

11.3 The Card Utility may check for updates and connect to the Service to sign you in and download Cycles. It may include third-party components licensed under their own terms, which apply to those components.

12. 480 Trainer

12.1 The 480 Trainer is a free, browser-based simulation provided to help pilots learn the operation of the unit. It is original software and artwork; it is not produced, approved or endorsed by Garmin, and it may differ from the operation of a real unit and from the published pilot’s guide. It is not an approved flight training device, and time spent with it cannot be logged or credited toward any certificate, rating or currency requirement.

12.2 The Trainer’s navigation data, weather broadcasts (which may use information from the National Weather Service and other third parties) and other information are for training only. Do not use the Trainer for navigation, flight planning or weather briefing.

12.3 Using the Trainer requires a free 480data.com account; no Subscription is needed. The Trainer stores its data and settings in your browser. You may use it for personal, non-commercial training. Flight schools and instructors may use it in their training if they do not charge for access to the Trainer itself. Sections 6 and 8 apply to it.

13. Privacy

We collect the information needed to provide the Service: your name, phone number, email address and sign-in details (handled by our authentication provider, Amazon Cognito), your Subscription status and billing details (handled by Stripe), and records of the Cycles you download and when, and when you use the Trainer (the first and most recent use and the number of times it has been opened). We use this information to provide the Service, to enforce this Agreement, to prevent fraud, to contact you about your account and Subscription, and to meet legal obligations. We do not sell your personal information. We use a cookie to keep you signed in. The Trainer keeps its data in your browser; weather requests it makes go to our servers or to the National Weather Service with the location involved but no account information. Ask us at support@480data.com if you want to see or delete your account information; we keep billing and download records as long as the law or legitimate business needs require.

14. Disclaimer of warranties

To the maximum extent permitted by law, the Databases, the Card Utility, the Trainer and the rest of the Service are provided “as is” and “as available,” with all faults, and 480Data disclaims all warranties, express, implied or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, completeness, currency and quiet enjoyment, and any warranties arising from course of dealing or usage of trade. 480Data does not warrant that the Databases are free of errors, that they will work with any particular unit, card or software version, or that the Service will be uninterrupted or secure. No advice or information from 480Data creates any warranty not stated in this Agreement.

15. Limitation of liability

To the maximum extent permitted by law: (a) 480Data and its members, managers, employees, agents and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, data, use, goodwill, aircraft or property, arising out of or relating to this Agreement or the Service, however caused and on any theory of liability, even if advised of the possibility of such damages; and (b) the total liability of 480Data for all claims arising out of or relating to this Agreement or the Service will not exceed the amount you paid 480Data in the twelve months before the event giving rise to the claim.

Some jurisdictions do not allow certain warranties to be excluded or liability to be limited, so some of the limits above may not apply to you. These limits do not exclude liability that cannot be excluded by law. They are an essential part of the bargain between you and 480Data; without them we would not offer the Service at its price.

16. Assumption of risk and indemnification

16.1 Aviation involves inherent risk of property damage, injury and death. You acknowledge that you use the Databases, the Card Utility and the Trainer voluntarily and at your own risk, with full knowledge of the limitations in this Agreement.

16.2 You will defend, indemnify and hold harmless 480Data and its members, managers, employees and agents from and against all claims, losses, liabilities, damages, costs and expenses (including reasonable attorneys’ fees) brought by anyone, including passengers, other pilots and other users of your aircraft, arising out of or relating to (a) your use of the Service or the Databases in breach of this Agreement, including any use contrary to Section 5, (b) your violation of any law or regulation, or (c) the operation of any aircraft in which the Databases are installed.

17. Term and termination

17.1 This Agreement applies from when you first accept it until it is terminated. You may stop using the Service at any time and may close your account by writing to us.

17.2 We may suspend or terminate your account, your Subscription and your licenses at once, without refund, if you breach this Agreement, if we reasonably believe your use endangers safety or violates law, or if the law requires it. We may also discontinue the Service or any Database for everyone by notice to you; if we do so for reasons other than your breach, we will refund the unused part of your current term pro rata.

17.3 When this Agreement is terminated for your breach, all licenses to you end and you must stop using, and delete, all Databases and copies of the Card Utility. Sections 6, 7, 8 and 13 to 21, and any unpaid payment obligations, survive termination.

18. Governing law, disputes and class action waiver

18.1 Governing law. This Agreement and any dispute arising out of or relating to it or the Service are governed by the laws of the State of North Carolina, without regard to its conflict of laws rules, and by applicable federal law. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

18.2 Informal resolution. Before filing a claim, you and 480Data each agree to try to resolve the dispute informally by written notice (for you, to support@480data.com) and at least 30 days of good-faith discussion.

18.3 Courts. Any claim that is not resolved informally must be brought exclusively in the state or federal courts located in North Carolina, and you and 480Data consent to their personal jurisdiction and venue. Either party may bring an individual claim in small claims court where it qualifies, and 480Data may seek injunctive relief in any court of competent jurisdiction to protect its intellectual property.

18.4 Class action waiver. To the maximum extent permitted by law, you and 480Data each agree to bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated or representative action.

18.5 Time limit. To the extent permitted by law, any claim arising out of or relating to this Agreement or the Service must be brought within one year after it arises.

19. Changes to this Agreement

We may change this Agreement from time to time. We will post the changed Agreement on this page with a new “Last updated” date and, for material changes, notify you by email or in the Card Utility at least 30 days before they take effect. A material change to the license or to the terms of your Subscription takes effect for you at your next renewal. If you do not agree to a change, you may cancel before it takes effect; continuing to use the Service after it takes effect means you accept it.

20. General

20.1 Entire agreement. This Agreement, together with the price and billing terms shown when you subscribe, is the entire agreement between you and 480Data about the Service and supersedes all prior understandings.

20.2 Severability and waiver. If any provision is held unenforceable, it will be enforced to the maximum extent permitted and the rest of this Agreement remains in effect. A failure to enforce a provision is not a waiver of it.

20.3 Assignment. You may not assign or transfer this Agreement or your Subscription except as Section 4.2 allows. 480Data may assign this Agreement in connection with a merger, acquisition or sale of its business or assets.

20.4 Force majeure. 480Data is not responsible for delay or failure caused by events beyond its reasonable control, including changes to or unavailability of FAA data or services, failures of hosting or payment providers, and acts of government.

20.5 Export. You will comply with United States export control and sanctions laws and will not export or use the Databases, the Card Utility or the Trainer in violation of them.

20.6 U.S. Government users. The Databases, the Card Utility and the Trainer are “commercial items” and “commercial computer software” licensed to government users only on the terms of this Agreement.

20.7 Notices. We may give you notices by email to the address on your account, in the Card Utility or on this site. You may give us notices at the address in Section 21. Headings are for convenience only; “including” means “including without limitation.”
