With engine bleed for packs off, increase gradient by 0.2%.
With engine anti-ice on, decrease gradient by 0.1%.
With engine and wing anti-ice on, decrease gradient by 0.3%.
When operating in icing conditions during any part of the flight with forecast landing temperatures below
10°C decrease gradient by 0.9%.

Increase weight by 700 kg per 1% uphill slope.  Decrease weight by 1200 kg per 1% downhill slope. Increase weight by 1850 kg per 10 knots headwind.  Decrease weight by 7750 kg per 10 knots tailwind.
After landing at weights exceeding those shown above, adjusted for slope and wind, wait at least 67 minutes and check that wheel thermal plugs have not melted before executing a subsequent takeoff.
