// Interpretation

VFR — ceiling 19,000 ft. Light winds at 170°/6 kt, visibility better than 10 statute miles, a few at 2,500 ft, scattered at 3,800 ft, and broken at 19,000 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.
