// Interpretation

VFR — ceiling 4,100 ft. Moderate winds at 290°/9 kt, visibility better than 10 statute miles, scattered at 2,900 ft, broken at 4,100 ft, and overcast at 5,500 ft. 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.
