// Interpretation

VFR with light winds at 180°/7 kt. Visibility better than 10 statute miles and scattered at 9,500 ft. 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.
