L=1/2ρ.v2.S.CL ... ✈️L = Lift ... ✈️CL = Co-efficient of Lift. This is a number between 0 and 2 worked out by the clever folk who are involved in aircraft design and engineering. Us pilots don't have to worry too much about this number, just that it is a part of the all important Lift Formula, and that it is affected by the *Angle of Attack* of the wing, and the *Shape of the wing*. ... ✈️1/2 p - Rho Rho relates to the density of the air at the level and in the conditions in which you are currently flying. ... ✈️v - Velocity squared Velocity relates to the speed at which you are flying. Notice its effect is squared, so it has a very significant impact on the creation of lift. ... ✈️s - the Surface Area of a Wing This is the square foot / meter of the wing.
