Beschreibung
Zusammenfassung:	A method for starting a wind turbine with hinged wind turbine blades, the wind turbine further comprising an adjustable biasing mechanism arranged to apply an adjustable biasing force to each wind turbine blade which biases the wind turbine blade towards a position defining a minimum pivot angle. The biasing mechanism is adjusted to apply a predefined biasing force to each wind turbine blade, and the pivot angle of each wind turbine blade is monitored. The wind turbine is started in the case that the pivot angle of at least one wind turbine blade exceeds a predefined pivot angle threshold.
