1. A method of performing load mitigation on a non-mounted rotor blade of a rotor blade assembly, wherein the method comprises the steps of:
arranging an actuatable lift-modification device of a load mitigation arrangement on a surface of the non-mounted rotor blade;
monitoring loads acting on the non-mounted rotor blade;
actuating the actuatable lift-modification device based on the monitored loads, and
removing the actuatable lift-modification device after the non-mounted rotor blade has been mounted to a hub of a wind turbine.
