// Interpretation

MVFR — visibility 3.1 SM. Winds calm, visibility 3.1 SM, a few at 2,600 ft. Reported weather: haze (HZ). Haze is fine dust, salt, or pollution particles suspended in dry air — it reduces visibility and washes out contrast, a dry particulate obscuration rather than a moisture one. 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.

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.
