Landing-zone details (surface, obstacles, access, livestock) must be verified locally before every flight. Always cross-check with local clubs and pilots.

Fine-mesh models (1–3 km: HRDPS, AROME, ICON-D2, HRRR) resolve terrain and thermals well, but only reach +1 to +2 days. Use them for the day you actually fly.
Coarse-mesh models (10–25 km: GDPS, ARPEGE, ECMWF, GFS) miss valley detail but reach +3 to +10 days. Use them to scout a window 3+ days out, then re-check on a fine-mesh model the day before.
