Question

If an aircraft exhibits positive static and dynamic longitudinal stability, then

if upset from its trimmed condition it will return to trimmed condition with diverging oscillations.

if upset from its trimmed condition, it will return to trimmed condition with converging oscillations.

if upset from trimmed condition, it will not return to its trimmed condition.

if upset from trimmed condition, it will stabilize at a different trimmed condition.

if upset from its trimmed condition it will return to trimmed condition with diverging oscillations.

if upset from its trimmed condition, it will return to trimmed condition with converging oscillations.

if upset from trimmed condition, it will not return to its trimmed condition.

if upset from trimmed condition, it will stabilize at a different trimmed condition.

Explanation / Answer

incorrect top answer. In fact, it doesnt even properly answer the question

Positive stability= returns to position

Negative stability= continues away from trimmed condition

neutral stability= remains at upset position.

A positive stability aircraft may oscillate a little bit but will settle back to original position and oscillations will stop = converging oscillations.

diverging oscillations are oscillations that continue to grow in strength.

Answer is B.
