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 (S_{r}) is computed as as the square root of the Load Factor multiplied by the original stall speed (S_{0}). 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 °).
