// Interpretation

IFR conditions — visibility 1.6 SM. Winds calm, visibility 1.6 SM, no reported cloud layers. Reported weather: mist (BR). Mist is water droplets thinning visibility to between 5/8 and 6 SM — the moist, lighter cousin of fog. Would deteriorate to LIFR below 500 ft ceiling or 1 SM, or improve to MVFR above 1,000 ft and 3 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.
