Abstract
The present invention relates to a method for operating a wind turbine (). The wind turbine () comprises one or more wind turbine blades (), each wind turbine blade () being connected to a blade carrying structure () mounted on a hub (), via a hinge () at a hinge position of the wind turbine blade (), each wind turbine blade () thereby being arranged to perform pivot movements relative to the blade carrying structure () between a minimum pivot angle and a maximum pivot angle. The method comprises the steps of detecting an airborne object entering a predefined zone around the wind turbine (), comparing a current tip height (H) of the wind turbine () to a maximum tip height value, the maximum tip height value representing a maximum allowable tip height under currently prevailing conditions. In the case that the current tip height (H) exceeds the maximum tip height value, a pivot angle (P) of wind turbine blades () is adjusted in order to decrease the tip height (H) of the wind turbine () to a value below the maximum tip height value.
