Question

Horizontal stabilizer is away from wing wake in T-tail configuration.

(a) True

(b) False

I have been asked this question during a job interview.

My question comes from Tail Geometry and Arrangement topic in chapter Airfoil and Geometry Selection of Aircraft Design

Answer 1

Correct choice is (a) True

The best I can explain: In T-tail configuration tail will look like letter T viewed from front. In T-tail horizontal stabilizer is at top of the vertical tail. This arrangement ensures that the horizontal stabilizer is away from wing wake.
