Which risk increases significantly when a drone's airspeed drops excessively?

💡 Explanation

A stall greatly increases because decreasing airspeed reduces the angle of attack beyond its critical limit causing turbulent airflow and a loss of lift, rather than efficient, stable flight. Therefore stall occurs; rather than RPM increase or GPS errors which are separate.
