MVFR — visibility 4.3 SM. Light winds at 250°/5 kt, visibility 4.3 SM, broken at 4,000 ft. Would drop to IFR below 1,000 ft ceiling or 3 SM visibility, or rise back to VFR above 3,000 ft and 5 SM.

HLLM · day 12 at 23:00 UTC · wind from 250° at 5 kt · visibility 4.3 SM · broken layer at 4,000 ft · temp 26°C / dewpoint 13°C · altimeter 30.03" Hg
// Runway analysis · computed from current METAR wind
// Density altitude · ISA +11°C
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.
