Drone Wind Limit Checker (m/s)
Compare measured wind against your drone's rated wind resistance — with gust handling and the altitude wind-gradient trap accounted for.
The wind you feel at head height understates the wind at 100 m by 30–40% in open terrain — the power-law profile is why drones that launched fine struggle to come home.

About Drone Wind Limit Checker (m/s)
The classic drone-loss story isn't a crash — it's a copter pinned at full tilt, crawling backward away from home. The villain is the wind gradient: the breeze at your launch point understates the wind at working altitude by a third or more. This checker applies the standard power-law profile to estimate wind and gusts at your planned height, compares the worst case against the airframe's rated resistance, and even estimates your effective ground speed coming home against it.

Frequently asked questions
Why does my drone struggle at altitude when the ground wind seems fine?+
Surface friction slows the lowest air. In open terrain, wind at 100 m runs roughly 1.4× the 10-m value (power-law exponent ≈ 0.143); over rougher suburbia the multiplier is larger still. A 7 m/s ground breeze becomes ~10 m/s at working height — bumping against a 12 m/s rating before gusts are even counted.
What does a drone's wind-resistance rating actually mean?+
Typically the maximum steady wind in which the flight controller can still hold position (often quoted as a Beaufort level, e.g. 'level 5 ≈ 10.7 m/s'). It is measured in clean conditions at modest altitude. At the rating, station-keeping consumes most of the thrust margin — leaving little for gusts, climbs, or flying home upwind at speed.
How should I plan the flight on a windy day?+
Fly the outbound leg upwind, so the wind helps the battery-critical return. Watch for the controller's wind warnings, keep the RTH battery reserve fatter than the default, and remember RTH itself flies a fixed speed — if the wind aloft nears your drone's max speed, RTH may make negative progress. The 'ground speed home' figure in this tool models exactly that.
Do gusts matter more than steady wind for a multirotor?+
Yes — attitude authority, not just thrust, is the binding constraint. A gust demands an immediate pitch change to hold position; at high steady wind the airframe is already tilted near its limit and the gust arrives with no authority left, producing position excursions or worse near obstacles. This tool scales your reported gust up the same profile and judges the margin against it.
