Terms of use

Last updated: July 2026.

The short version

Charlie Center is a free education and entertainment site. Play the games, learn some aviation, enjoy the book if you buy it. Be decent, don't abuse the service, and understand that everything here is provided as-is.

Built with AI — and provided as-is

This site — its games, code, and much of its text — was built with the substantial assistance of artificial intelligence, working under human direction. We test carefully and correct what we find, but AI-assisted work can contain mistakes, and aviation facts simplify complex reality. The site and its games are provided "as is" and "as available", without warranties of any kind, express or implied — including accuracy, availability, fitness for a particular purpose, or that scores and progress will never be lost. Nothing here is operational, professional, or training advice: it is general education and entertainment. To the fullest extent permitted by law, Charlie Center and its operator accept no liability for any loss or damage arising from use of, or reliance on, this site.

The games

Game scores, streaks, ranks, and progress are for fun. They live mainly in your own browser, may be reset by us if something breaks or is abused, and have no monetary value. Automated play, score manipulation, and attacks on the service are not welcome and may be blocked.

Content and photography

Photographs are used under open licenses with attribution shown where each photo appears — details on thecredits page. Airline and manufacturer names appear only to identify their subjects; all trademarks belong to their owners, and no affiliation or endorsement is implied. Book purchase links lead to Amazon, whose own terms apply there.
