// Interpretation

VFR with light winds at 020°/6 kt. Visibility 5.6 SM and no reported cloud layers. 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 shift to MVFR if the ceiling drops to 3,000 ft or visibility below 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.
