// Interpretation

VFR — ceiling 16,000 ft. Moderate winds at 280°/9 kt, visibility better than 10 statute miles, scattered at 2,500 ft, scattered at 3,000 ft, scattered at 3,600 ft, and broken at 16,000 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.
