Effects
Unless countered, dissymmetry causes the helicopter to roll to the retreating side.
When dissymmetry causes the retreating blade to experience less airflow than required to maintain lift, a condition called retreating blade stall occurs. This causes the helicopter to roll to the retreating side and pitch up (due to gyroscopic precession). Once this dangerous condition arises, control may be lost, resulting in loss of the aircraft.
