// Interpretation

VFR — ceiling 9,300 ft. Moderate winds at 330°/10 kt, visibility 6.0 SM, broken at 9,300 ft. Reported weather: smoke (FU). Smoke aloft is most often wildfire smoke drifting into the area — fine particulates that scatter light and cut visibility even though the air itself stays dry, so it behaves differently from moisture-based mist or fog. Would shift to MVFR if the ceiling drops to 3,000 ft or visibility below 5 SM.

Approximate using ~10% perf loss / 1,000 ft DA for normally aspirated, scaled by powerplant type. Verify with your aircraft's POH for accurate numbers — especially above 5,000 ft DA where these rules of thumb diverge. Severity rating assumes a standard altimeter setting (29.92" Hg / 1013 hPa); a non-standard setting shifts the effective altitude by roughly 1,000 ft per 1" Hg of deviation.
