Learn to decode the winds aloft forecast - four-digit encoded groups, true vs. magnetic direction, and how altitude selection changes every cross-country you fly.
Decode the FD winds aloft forecast - four-digit wind codes, heavy wind encoding, and temperature data - to make confident altitude decisions before every cross-country flight.
Every winds aloft forecast pilots rely on traces back to a global network of 900 balloon-launched radiosondes that measure the atmosphere twice daily from surface to near-space.
Decode the Winds and Temperatures Aloft Forecast (FD winds) and learn how to use altitude-by-altitude wind data to pick the best cruise altitude for your cross-country.
