Question

q9. powered up aircraft create a condition known as ________ that can create a force of wind behind the aircraft that can propel objects or debris. (select all that apply)

Explanation:

Jet blast refers to the high-speed airflow from jet engines, and propeller wash is the airflow generated by propellers, both creating wind forces behind powered aircraft that can propel objects. Engine energy is a general term, and flight damage is unrelated to wind force.

Answer:

C. Jet blast, D. Propeller wash
