What reaction might an aircraft experience from wake turbulence?

Wake turbulence is a phenomenon caused by the passage of an aircraft through the air, leading to the formation of rotating air patterns behind it, particularly from the wingtips. When another aircraft encounters this wake, it can experience various effects depending on factors like size and weight.

The correct answer indicates that an aircraft might encounter potential choppy air conditions when flying through wake turbulence. This choppy air occurs as the trailing vortices from a preceding aircraft can create sudden changes in airflow, leading to abrupt movements of the aircraft that may feel similar to bumps or turbulence. Pilots are trained to recognize and respond to these types of conditions, often by maintaining specific separation distances from larger aircraft to minimize the risk of encountering significant wake turbulence.

The other choices do not accurately reflect the nature of the interaction with wake turbulence. A smooth flight experience is unlikely in the presence of wake turbulence, as it can disrupt the stable airflow around the aircraft. Enhanced fuel efficiency and increased altitude are also unrelated to the effects of wake turbulence, as these are not typical outcomes associated with encountering turbulent air caused by another aircraft.
