What is the designation of the V-Tail aircraft made by Beechcraft?

The designation of the V-Tail aircraft made by Beechcraft is indeed known as the BE35. This model, commonly referred to as the Beechcraft Bonanza, features a unique V-shaped tail design. The BE35 was developed in the 1940s and is notable for its combination of performance, comfort, and distinctive style. The V-Tail design contributes to the aircraft's aerodynamic efficiency, reducing drag and enhancing flight performance compared to more traditional tail designs. The emphasis on sleek design and engineering innovation has made the Beechcraft Bonanza a popular choice among general aviation pilots.

The other options do not correctly represent the V-Tail designation; VTA1 and BCT35 do not correspond to any known Beechcraft models, while BT35 is not specifically associated with the V-Tail variant. This further solidifies that BE35 is the correct and recognized designation for the aircraft in question.
