Helicopters have unique stability and control characteristics not seen in other aircraft. In this section we discuss helicopter flight, controls and stability. It includes a high-level introduction to the primary flight controls that a pilot uses to fly a helicopter: Helicopter Flight Controls. Aspects of the helicopter's response to pilot control inputs are discussed in our article on helicopter stability: Helicopter Stability. Undesirable "off-axis" responses to pilot control inputs are discussed in this article: Off-Axis Control Responses.
For more detailed / technical information about the forces exerted on pilot sticks and pedals see this article: Control Forces. For technical notes about collective control rigging for autorotation see this: Control Rigging for Autorotation. To learn more about autorotation - how a helicopter glides to the ground upon engine failure - see this: Helicopter Autorotation.
