1. A method for manufacturing a wind turbine blade, the method comprising:
a) positioning an outboard blade section at a predefined end position, the outboard blade section comprising an outboard end portion;
b) positioning an inboard blade section adjacent to the outboard blade section, the inboard blade section comprising an inboard end portion having a root portion with a blade root plane;
c) determining a deviation of a current position of the blade root plane of the inboard blade section with respect to the outboard end portion of the outboard blade section from a nominal position of the blade root plane with respect to the outboard end portion, wherein, in step c), a vector is determined pointing from the blade root plane towards a predicted position of the blade tip, the predicted position being predicted based on the current position of the blade root plane and assuming an assembled blade; and
d) moving the inboard blade section relative to the outboard blade section to compensate for the deviation, wherein, in step d), the inboard blade section is moved relative to the outboard blade section until the vector points towards the actual position of the blade tip of the outboard blade section.
