    There is a discussion of longitudinal stability in Chapter 4 of the Pilot’s Handbook of Aeronautical Knowledge that talks about Center of Pressure (Center of Lift).

    The lift equation also appears in Chapter 4 under Lift/Drag ratio. You will see that Center of Pressure is not one of the terms in that equation.
