Terms of use

Panalucent LLC — CircumFlight airport pages. Effective 2 November 2026.

These terms cover the airport pages at this address (the “Site”). The Site is operated by Panalucent LLC (“Panalucent”, “we”, “us”). By using the Site you agree to these terms. If you do not agree, please do not use it. The CircumFlight app has its own End User License Agreement, which governs the app.

1. Not for navigation, not for operational use

THE SITE AND EVERYTHING ON IT ARE FOR GENERAL INFORMATION AND SITUATIONAL AWARENESS ONLY. THEY ARE NOT FOR NAVIGATION AND NOT FOR OPERATIONAL USE, AND MUST NOT BE THE BASIS OF ANY FLIGHT DECISION. OBTAIN A COMPLETE BRIEFING FROM AN OFFICIAL SOURCE, INCLUDING NOTAMS, AND USE CURRENT OFFICIAL PUBLICATIONS, BEFORE EVERY FLIGHT. FOLLOW ATC INSTRUCTIONS. RELIANCE ON THE SITE MAY RESULT IN DAMAGE TO PROPERTY AND IN INJURY OR DEATH TO YOU AND TO OTHERS.

2. Where the information comes from

Airport facts come from the FAA's National Airspace System Resources (NASR) for the current 28-day cycle; weather reports and forecasts from the National Weather Service Aviation Weather Center; procedure charts and Chart Supplement pages are links to the FAA's own files. NOTAMs, D-ATIS, arrivals and departures and the release queue are derived by CircumFlight from air traffic management information; they are not FAA data, they may be incomplete, delayed or wrong, and they are never a substitute for an official briefing or for ATC. Airport geometry in the 3D view is derived from OpenStreetMap.

Republished information lags its source and can contain omissions and discrepancies. We make no warranty that anything on the Site is current, complete or accurate, and it is your responsibility to check it, including its effective dates, against the official source. If you notice an error, please tell us through the contact page: a report from a pilot who was there is worth more than any check we can run.

3. Aircraft privacy

We honour the FAA's Limiting Aircraft Data Displayed (LADD) programme. Aircraft whose owners have asked the FAA to limit the display of their flights are not shown on the Site.

4. How you may use the Site

You may view the Site in a web browser for your own information. Without our prior written permission you may not:

• use any robot, script, crawler or other automated means to access, copy or collect the Site or its data, other than a general-purpose search engine indexing it for search results;
• download, copy, extract, decode, export, scrape, harvest, repackage, republish or resell the Site's data or the 3D airport models it delivers, or circumvent the measures that protect them, including the verification step and per-visitor model keys;
• use the Site's data to build, train, populate or maintain any other dataset, database, product or service; or
• overload, disrupt or interfere with the Site, or try to get around rate limits or checks.

Some of the information comes from public or openly licensed sources: the FAA and the National Weather Service (United States government works) and OpenStreetMap (© OpenStreetMap contributors, available under the Open Database License). Nothing in these terms limits any right you have to obtain and use that information from its source under that source's terms. These terms restrict the copy we deliver, the form we deliver it in, and what we add to it.

We license our data to others and like working with people who build things. If you want to use it outside the Site, write to us through the contact page.

5. Links to other sites

Charts and other documents open from the FAA's own servers, and the Site links to other sites. We do not control them and are not responsible for their content or availability. A link is not an endorsement, and nothing on the Site implies that the FAA or any other agency endorses us.

6. No warranty

THE SITE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, CURRENCY, AVAILABILITY OR NON-INFRINGEMENT.

7. Assumption of risk; release and indemnification

YOU KNOWINGLY AND VOLUNTARILY ASSUME ALL RISK ARISING FROM YOUR USE OF THE SITE AND FROM RELIANCE ON ITS INFORMATION. TO THE MAXIMUM EXTENT PERMITTED BY LAW, YOU, ON BEHALF OF YOURSELF AND YOUR HEIRS, EXECUTORS, ADMINISTRATORS, ESTATE, SUCCESSORS AND ASSIGNS, RELEASE, AND AGREE TO INDEMNIFY, DEFEND AND HOLD HARMLESS, PANALUCENT LLC AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, LICENSORS AND DATA PROVIDERS FROM AND AGAINST ANY AND ALL CLAIMS, LIABILITIES, DAMAGES, LOSSES, COSTS AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) ARISING OUT OF OR RELATING TO YOUR USE OF, OR RELIANCE ON, THE SITE OR ITS INFORMATION, INCLUDING CLAIMS FOR PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

You also agree to indemnify, defend and hold harmless Panalucent LLC and its officers, directors, employees, agents, licensors, data providers and affiliates from and against any claims, damages, losses, liabilities, costs and expenses (including reasonable attorneys' fees) arising out of your misuse of the Site or any breach of these terms.

8. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, PANALUCENT LLC AND ITS AFFILIATES ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA OR GOODWILL, OR FOR ANY DAMAGES ARISING FROM DEATH OR PERSONAL INJURY, ARISING OUT OF OR RELATING TO THE SITE. OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM RELATING TO THE SITE SHALL NOT EXCEED FIFTY U.S. DOLLARS (USD $50).

9. Privacy

The Site has no accounts. To keep it available and to stop automated copying, we process your IP address, apply rate limits and may ask you to complete a Cloudflare Turnstile check. If you use “nearest airport”, your browser asks your permission and sends a position rounded to about a kilometre, used once to choose the airport and not kept. Your browser stores your last airport and display choices on your own device. The privacy policy describes how Panalucent handles personal information.

10. Governing law and disputes

These terms are governed by the laws of the State of Florida, without regard to conflict-of-law principles. Any dispute arising under or relating to these terms or the Site shall be resolved exclusively by binding arbitration in Florida, administered by the American Arbitration Association under its Commercial Arbitration Rules. You waive any right to participate in a class action.

11. General

If any provision of these terms is held unenforceable, it applies to the fullest extent the law allows and the rest remain in effect; in particular, any warranty disclaimer, limitation of liability, release or arbitration provision held unenforceable in part applies to the fullest extent permitted. Our failure to enforce a provision is not a waiver of it. We may change or discontinue the Site at any time, and we may change these terms by posting a new version with a new effective date; using the Site after that means you accept the change. We reserve the right to publish any formal legal demand, complaint or notice sent to us.
