Which option is a T-tail?

• A. T tail
• B. V tail
• C. Conventional tail
• D. Twin Boom tail

Answer: (A)

A T-tail is defined by having the horizontal stabilizer mounted on top of the vertical stabilizer, forming a top-mounted tailplane that looks like a “T.” This placement keeps the tailplane out of the wing’s wake in normal flight, which can improve pitch control at low speeds and reduce interference from the horizontal tail with the fuselage authorizations. However, it can make the elevator less effective in a deep stall because turbulent air from the wing can blanket the tail.

Other tail configurations place the stabilizer differently: a conventional tail has the horizontal stabilizer at the base of the vertical stabilizer near the tail of the fuselage, a V-tail uses two surfaces arranged in a V shape, and a twin boom tail carries the tail surfaces on separate booms rather than on the main fuselage.
