// Interpretation

LIFR — ceiling 300 ft. Light winds at 220°/5 kt, visibility 4.3 SM, overcast at 300 ft. LIFR is the lowest standard category. Would improve to IFR above 500 ft and 1 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.
