In flight mechanics and aerodynamics, typically represents the coefficient of lift for an unknown or specific condition. The coefficient of lift () is a dimensionless parameter used to quantify the lift generated by an airfoil, wing, or aircraft at a particular angle of attack or flight condition.
- represents the coefficient of lift for the unknown condition.
- is a multiplication factor that relates the lift coefficients for the unknown and reference conditions.
- represents the coefficient of lift for the reference condition.
