Blade feathering is possible on WTs with adjustable pitch. The blades are rotated so the chord is pointing upwind which, when the blade is in motion, gives a negative angle of attack which will rapidly slow the rotor to a standstill. This effect can be used to assist WT cutout in very high winds and as an emergency brake. In very high winds, if the WT can be parked with the blades feathered, this will reduce the loads on the whole WT.
