Answer:
Option b) True
Explanation:
The main purpose of horizontal tail structure in a typical aircraft is to impart stability to the structure and to ensure a straight flying position of the aircraft. It helps in preventing the pitching motion or up and down motion of the nose of an aircraft nose as a result of the moment created by upward force or lift and downward force due to gravity. The lift or force is applied at horizontal structure at its center of pressure at a distance from the center of gravity of aircraft resulting in the generation of torque.
