// Interpretation

LIFR — ceiling 200 ft. Light winds at 350°/7 kt, visibility 0.00 SM, overcast at 200 ft. Reported weather: fog (FG). Fog is water droplets suspended at the surface with visibility under 5/8 SM; it typically burns off with daytime heating or a pickup in wind. 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.
