One tap gives you a clear GO / CAUTION / NO-GO read for your exact spot — and the next 3 hours. We hold live wind, gusts, visibility, rain, and clouds up against the same Part 107 weather rules you'll answer for on the exam, so you start reading the sky the way a certified remote pilot does — not just deciding whether today's a good day to launch.
Your location is used once to pull the local forecast and is never stored or sent anywhere but the weather service.

Each hour's call comes from the worst of these checks — two are hard Part 107 rules you'll be tested on, the rest are common-sense limits most drones share. Learn the pattern here and you'll be able to size up any forecast on your own.
| Factor | Go | Caution | No-Go |
|---|---|---|---|
| Visibility (Part 107) | 5 SM+ | 3–5 SM | Under 3 SM |
| Wind / gusts | Calm–14 mph | 15–24 mph | Over ~24 mph |
| Precipitation | None | 50%+ chance soon | Rain/snow falling |
| Thunderstorms | None | — | In the area |
| Temperature | 33–103°F | ≤32°F or ≥104°F | — |
| Daylight (Part 107) | Day | Night — needs anti-collision lighting | — |
Reading conditions like these is exactly what test day asks of you — decode a METAR, spot a low ceiling, know your minimums cold. Keep building that confidence with the rest of the free weather tools:
Paste a raw METAR and see it in plain English, with the Part 107 read — until the code stops looking like a foreign language.
Decode a METAR →See what's coming — decode the forecast and every change window, so nothing on test day catches you off guard.
Decode a TAF →Weather's clear — but is the airspace? Learn when you need LAANC authorization before you launch.
Check airspace →Weather data by Open-Meteo.com. Fly107Prep is an independent study tool and is not affiliated with or endorsed by the FAA.
The full Fly107Prep app builds that same confidence across weather, airspace, and chart reading — with explanations that teach you why each answer is right, so you understand the rule instead of memorizing it. You get 800+ worked questions, a no-supplement exam mode built for the new format, and a 22-lesson course that walks you all the way to test-ready. One-time $39.99, 7-day money-back guarantee.
