Question

Stick fixed and stick free are similar.

(a) True

(b) False

The question was asked in an internship interview.

My doubt stems from Stick-Free Stability topic in chapter Stability, Control, and Handling Qualities of Aircraft Design

Answer 1

Correct choice is (b) False

To explain I would say: No, stick free and stick fixed are not similar. Floating of elevator is permitted in stick free however, in stick fixed elevator is not permitted to float. In stick fixed, some desired elevator deflection is given as required. At that position, elevator is fixed and not allowed to float.
