1.	What is the use of V type tail?(a) To reduce wetted area(b) To increase wetted area(c) To prevent adverse yaw roll(d) To produce thrustThis question was posed to me during an interview for a job.This interesting question is from Tail Geometry and Arrangement topic in division Airfoil and Geometry Selection of Aircraft Design
Answer» Correct choice is (a) To reduce wetted area Easiest explanation: V tail arrangement is used to combine HORIZONTAL and vertical tail. It combines in such WAY that the wetted area reduces. However, it generates adverse yaw roll MOTION. To prevent such EFFECT INVERTED V tail can be used.
