The longitudinal stability curve shown below reflects the case for zero elevator deflection and the center of gravity at the design location.

$4\mathrm{.}1$ Mark the location of the equilibrium position with an E$.$

$4\mathrm{.}2$ Sketch the curve for the elevator deflected upward and the center of gravity at the design location. Label this curve B$.$

$4\mathrm{.}3$ Sketch the curve for the elevator deflected upward the same amount as in the previous part, but with the center of gravity at the most forward position. Label this curve C$.$

$4\mathrm{.}4$ Sketch the curve for the elevator deflected upward the same amount as in the previous parts, but with the center of gravity at the neutral point. Label this curve D
