How do gusts impact runway wind calculations?

When winds are reported with gusts (e.g., 15 gusting to 25 knots), pilots must calculate crosswind components for both the sustained wind and the peak gust speed. The aircraft’s maximum demonstrated crosswind limit must not be exceeded by the peak gust component.

Is a tailwind always dangerous on landing?

Yes. A tailwind significantly increases true ground speed at touchdown, increases landing rollout distance exponentially (often doubling stopping distance on contaminated runways), and degrades directional control authority.

Runway Wind Frequently Asked Questions

Everything you need to know about cash runway, burn rates, and financial planning.

A runway wind calculator resolves total wind speed and direction into two perpendicular vectors: the headwind/tailwind component aligned with the runway centerline, and the crosswind component perpendicular to the runway. This allows pilots to check safe aircraft operating limitations.
