How Load Factor and Stall Speed are calculated

The Load Factor (L) — which is experienced by the aerofoil (and occupants!) has the unit of G — is calculated with the mathematical Sine function using the bank angle (θ). Next, a revised stall speed (Sr) is computed as as the square root of the Load Factor. This revised stall speed is always greater with increased Load Factor and Bank Angle as when banked the vertical lift factor becomes less. As this is not a linear relationship, at low bank angles and hence lower Load Factors, the stall speed does not increase much. The effect is more pronounced at steep bank angles (those > 30 °).
