CYNM · day 25 at 18:00 UTC · wind from 310° at 9 kt · visibility 9.0 SM · temp 20°C / dewpoint 7°C · altimeter 29.99" Hg · sea-level pressure 1016.1 mb

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. Severity rating assumes a standard altimeter setting (29.92" Hg / 1013 hPa); a non-standard setting shifts the effective altitude by roughly 1,000 ft per 1" Hg of deviation.
