In the engineer's lift formula L = Cl * (1/2)p * v^2 * s, what does s represent?

Explanation:
Lift depends on how much wing area is pushing air downward, the air’s density and speed, and the lift coefficient. In the formula, the dynamic pressure is the part (1/2) p v^2, with p as air density and v as velocity. The remaining factor S is the wing’s surface area (the planform area). Multiplying the dimensionless lift coefficient by dynamic pressure and by the wing area gives the lift force. So s represents the wing surface area.
