Inputs:
1. The Air Temperature should ideally be the temperature of the air that is going into the intake of your engine.
2. The Absolute Pressure (also called actual pressure or station pressure) is the ambient air pressure.
3. Relative Humidity is a measure of how much moisture is in the air compared to the amount of moisture that the air could hold at saturation.
