Question

As an aircraft burns fuel, its CG shifts, requiring control surface adjustments to "trim" the aircraft and maintain level flight. Consider the Cessna aircraft shown, for which relevant geometric information

for the two lifting surfaces are provided. Assume the wing and horizontal tailplatorms are rectangular in shape as viewed from above. If the wing is installed with a 2.5 degree angle of attack,determine the deflection of the tail necessary to balance moments about the CG. Assume the tail can be rotated about its quarter chord point. Assume thin airfoil theory.
