Your location is used once to pull the local forecast and is never stored or sent anywhere but the weather service.

The verdict for each hour is the worst of these checks — two of them are actual Part 107 rules, the rest are common-sense limits most drones share.
| 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 | — |
