Relative Humidity

Hi all,

I wonder how do you consider relative humidity for take off computations?

Relative Humidity, especially at high temperature, would reduce air density and thus take off performances.
I think about it especially for operations in the Gulf during summer season, with very high temperatures (>40°C) and high relative humidity (80%).

I did not see any performance computation requesting RH and I do not remember if SCAP modules allowfor Relative Humity input .

Is this included in QNH?

Thanks in advance for your help!
