Which formula represents the calculation for lift in aviation?

• A. Lift = 1/2pV^2S
• B. Lift = pV^2S/2
• C. Lift = CL 1/2pV^2S
• D. Lift = CL pV^2/S

Answer: (C)

The correct formula for calculating lift in aviation is represented by the choice that includes the coefficient of lift, denoted as CL. The formula is expressed as Lift = CL * 1/2 * p * V^2 * S. In this formula: - CL is the coefficient of lift, which varies based on the airfoil shape, angle of attack, and flow conditions. - p represents the air density, an essential factor that influences lift. As the air density increases, lift increases. - V is the velocity of the aircraft relative to the air, which is squared in the formula, indicating that lift increases with the square of velocity; doubling the speed will quadruple the lift. - S is the wing area, reflecting that the lift is directly proportional to the size of the wing. This formula illustrates the fundamental relationship between these variables and shows how lift can be manipulated through aerodynamic design and operational adjustments. On the other hand, while options that do not include the coefficient of lift (like the first two options) provide a simplified perspective of lift, they lack the necessary detail to accurately depict how lift is affected in practice. The formula that divides by two without the coefficient of lift is not reflective of standard aviation calculations. The choice that
