FAQ

Frequently asked questions

Quick answers on accuracy, data, coverage, and cost.

How accurate is it? ▾
It uses NOAA's Graphical Turbulence Guidance (GTG) — the same government model professional dispatchers fly by. Validated on real US routes.
Where does the data come from? ▾
NOAA's free, public GTG turbulence model for US airspace. It's the open dataset behind most turbulence tools — we just translate it into one human sentence.
Does it cover my flight? ▾
US flights, for now. The free high-resolution turbulence model is US-only; global coverage would mean licensing or computing a coarser forecast, which we'd rather not ship until it's honest.
How fresh is the forecast? ▾
Refreshed hourly from the latest model cycle.
