Which consequence results when a jet aircraft experiences a jammed elevator control surface?

💡 Explanation

Unintended pitch oscillations occur because the elevator, crucial for longitudinal control, can no longer smoothly adjust; this induces a pilot-induced oscillation feedback loop rather than allowing for stable, controlled flight, therefore. Other control surfaces would not be directly affected at onset.
