Question

Typically tail provides ______

(a) stability

(b) control

(c) stability and control

(d) accelerating force

I had been asked this question during an interview.

Enquiry is from Tail Geometry and Arrangement in section Airfoil and Geometry Selection of Aircraft Design

Answer 1

Right choice is (c) stability and control

The best I can explain: Typically tail is used to provide stability and control. Accelerating force will be provided from engines. One of the main function of the tail is to provide enough stability and controllability to make aircraft fly smoother at the time of any disturbance.
