Student Pilot Crosswind Limit Checker
Solo-endorsement crosswind check: today's component against the wind limits your instructor wrote in your logbook, with conservative margins built in.
Solo endorsements under 14 CFR 61.87/61.93 routinely carry wind limits. This checker uses the gust as the wind โ the conservative reading every instructor intends.

About Student Pilot Crosswind Limit Checker
A student's solo wind endorsement is a contract written in knots, and the hardest part of honoring it is doing honest trigonometry in a noisy run-up area. This checker is built for that moment: it takes the ATIS wind (gusts included โ they count against you), the runway, and the limits from your endorsement, and returns margins rather than just components, with a verdict tuned to err toward the phone call to your instructor.

Frequently asked questions
Do gusts count against my endorsed wind limit?+
Read your endorsement literally, but almost every instructor means yes โ the limit protects you from the strongest air you'll meet, which is the gust. This tool always evaluates the gust value when one exists. If 'winds 12 gusting 19' meets a 15-knot limit, the answer is no-go, and your instructor will be pleased you treated it that way.
What are typical first-solo wind limits?+
Commonly: total wind 10โ15 knots, crosswind component 5โ8 knots, gusts either prohibited or capped at a small spread, sometimes 'winds within 30ยฐ of runway heading.' They tighten or loosen with the airport (wide vs narrow runway, one strip vs crossing runways) and the student's demonstrated consistency. Yours are whatever is written โ not the typical.
The wind is within limits but it feels beyond me today โ what now?+
Then it is beyond you today, and that judgment is exactly what your instructor is trying to grow. Endorsement limits are ceilings, not targets or dares. A documented decision to wait, with the components computed (screenshot this page), is the kind of aeronautical decision-making examiners ask about later.
How do I grow my crosswind limit after the checkride?+
Deliberately and with witnesses: book dual sessions specifically on gusty/crosswind days, work upward 2โ3 knots at a time, and log the actual components you handled (this calculator gives you the number for the logbook remark). A personal-minimums sheet that rises on evidence beats one that rises on optimism.
