Question

Which of the following is used to maintain the aircraft in a longitudinal balance?

(a) Vertical stabilizer

(b) Horizontal stabilizer

(c) Longitudinal stabilizer

(d) Diagonal stabilizer

This question was addressed to me by my school principal while I was bunking the class.

Query is from Aircraft Systems and Aviation in chapter Aircraft Systems and Aviation Overview of Aircraft Maintenance

Answer 1

Correct answer is (b) Horizontal stabilizer

For explanation I would say: In order to maintain an aircraft’s longitudinal balance, manufacturers use horizontal stabilizers. These stabilizers work so as to reduce the summation of pitch moments around the aircraft’s center of gravity to zero.
