// Interpretation

LIFR — ceiling 300 ft. Moderate winds at 030°/9 kt, visibility better than 10 statute miles, overcast at 300 ft. LIFR is the lowest standard category. Would improve to IFR above 500 ft and 1 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.
