Crosswind Limit Calculator

Know your limit before you fly.

WindLimit checks the wind against your aircraft and your personal minimums in real time, with live METAR winds and a plain warning the moment a runway is out of limits.

Free to download. No account. No subscription. Your settings stay on your device.

Why WindLimit

The math is quick until the day is not.

The crosswind component is a simple calculation, right up until it is gusting 25, you are tired, and the runway options are changing on you. WindLimit runs the numbers every time, against the values you actually fly, so the answer is on the screen instead of in your head.

RWY 27   WIND 240/22G31
XW 18 KT  OVER LIMIT (15)
RWY 33   XW 7 KT  WITHIN LIMITS
What you get

Built to answer one question fast: can I take this runway?

Your numbers, not generic ones

Set your aircraft's demonstrated crosswind and your own personal minimums once. Every reading is measured against those.

Every runway end, side by side

The runway picker shows crosswind and head or tailwind for both ends, with the better end badged, so you are not working them one at a time.

It tells you when you are over

When the wind exceeds your limit, WindLimit says so plainly. The crosswind figure shifts from normal to amber to red as it climbs.

Live winds from the official source

METAR, and TAF when you want it, pulled straight from aviationweather.gov. Only the airport identifier leaves your phone.

Find a runway that works

Nearby Airports lists fields around you with live wind, the best runway, and a within-limits read for each.

Who builds it

Made by a pilot who flies with it.

WindLimit is built and flown by a working regional airline first officer. It exists because a fast, honest crosswind check against real personal minimums is something every line pilot does and no free tool did well.

The one-time upgrade removes ads, adds the planning features, and helps keep the app maintained and current. No account is ever created, and nothing you enter in the app, not your airports, weather, aircraft, or minimums, is collected.

Questions

Before you download.

Is WindLimit a substitute for official weather or my operator's procedures?

No. It is an informational tool for situational awareness. Official weather sources, aircraft documentation, and your operator's procedures govern. The pilot in command remains responsible for every operational decision.

Do I need an account?

No. There is no sign-up and no login. Your airports, aircraft, and minimums stay on your device.

Does it work offline?

Your settings and aircraft profiles are stored on the device and load without a connection. Fetching live weather needs one.

What aircraft does it support?

Any. You enter the demonstrated crosswind and the limits you fly, so it works for a light single or a regional jet.

Is there a subscription?

No. The upgrade is a single purchase. If you would rather not buy, a rewarded ad unlocks the same features for 24 hours.

What platforms does it run on?

iPhone, on iOS. It is available on the App Store.

Know your limit before you fly.

Free on the App Store. One-time $2.99 upgrade to remove ads and unlock the planning tools.

WindLimit is an informational tool for situational awareness only. It is not a substitute for official weather sources, aircraft flight manuals, or your operator's procedures. Wind and weather data are provided by third parties and may be delayed or inaccurate. The pilot in command remains solely responsible for verifying limits and operating the aircraft within them.
