How autorotation is used to help land a helicopter safely if the engine fails?
Autorotation is a flight maneuver that allows a helicopter to land safely in the event of an engine failure. During autorotation, the pilot lowers the collective pitch, allowing the rotor blades to continue spinning due to the upward flow of air through the rotor system. This creates lift and allows the helicopter to descend in a controlled manner. The pilot then manages the descent rate and performs a flare just before landing to reduce vertical speed and ensure a safe touchdown.
