Free aviation tools, live data, and an EFB
FAA charts, georeferenced approach plates, live weather, airport information, calculators and learning resources — all built on official aviation data. No account to make. Run it in the browser, or get the iOS app.
What is on the map
Frames from the iPad app. Synthetic vision, the instrument bar, offline chart downloads and Direct‑To are in the iOS app only; everything else on this page runs in the browser too. ADS‑B traffic needs a portable receiver.
Tools, data and guides
Alongside the app there is a library — calculators that show their working, live rankings built from the same weather feed, and guides to reading the formats.
Calculators
Density altitude, crosswind component, wind correction and groundspeed, holding entry, top of descent, METAR decoder — and nine more, each with the formula behind the answer.
Airport weather
Live METAR and TAF, 48-hour trends, per-runway crosswind, density altitude, frequencies and procedures for 2,159 US airports that report their own weather. Browse by state.
Live visualizations
Where the weather is worst right now, which stations are watching pressure fall, winds aloft, and the whole US airport system charted.
Poster studio
Turn any US airport diagram or approach plate into a print-ready poster — the original vector chart, with the weather from a day that mattered set underneath it.
Learning resources
A free weather course following the CFI ACS — thunderstorms, icing, turbulence, fog — with drills on live reports.
Also on iPhone and iPad
The same EFB ships as a native app, which adds offline chart downloads and Sim Connect, which reads position from a flight simulator on your network. The web version needs no installation and works on any device with a browser.
Flying a simulator?
A free Windows program feeds Microsoft Flight Simulator or X-Plane straight into the app, so your aircraft moves on the chart while you fly at your desk. It finds the simulator on its own and needs no configuration. Sim Client for Windows →
What it is not
Flight Kneeboard is an advisory aid for situational awareness. It is not certified for navigation, and it is not a substitute for an official weather briefing or current paper or electronic charts. Always cross-check anything here against an official source before you fly.
Free, and no account. Nothing here asks you to sign up. See about for who builds it and privacy for what is and is not collected.
