// Interpretation

VFR — ceiling 15,000 ft. Light winds at 170°/5 kt, visibility 6+ SM, a few at 3,000 ft, and broken at 15,000 ft. Reported weather: -SHRA. 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.
