Aircraft A has \( V_H = 0.90 \) and aircraft B has \( V_H = 1.20 \), both with the same wing and tail arm. The ratio of B's tail area to A's is
Answer: D
Correct answer: 1.33
With the same wing and the same tail arm, the tail volume coefficient is proportional to the tail area, so the areas are in the ratio of the coefficients:
\[ \frac{S_B}{S_A} = \frac{1.20}{0.90} = 1.33 \]
The distractor 0.75 inverts the ratio. A difference of this size between two designs usually reflects a difference in requirement rather than in quality - a wider centre of gravity range, or a more demanding trim case at the forward limit, buys tail area.
