1. A method of handling a wind turbine comprising a nacelle coupled via a yawing system to a tower, the method comprising:
supplying a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation; and
exerting, by the yawing actuator, a torque to the nacelle relative to the tower, thereby turning the nacelle to a second orientation being a downwind orientation,
wherein the second orientation is defined with respect to an actual wind direction measured by one or more wind direction sensors or with respect to the first orientation,
wherein a definition of the second orientation is switched during the turning of the nacelle as a result of the torque exerted by the yawing actuator, depending on an availability of a wind direction signal provided by the one or more wind direction sensors.
