// Interpretation

VFR — ceiling 3,400 ft. Light winds at 140°/5 kt, gusting 12, visibility better than 10 statute miles, broken at 3,400 ft, and overcast at 4,500 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.
