1. A method for manufacturing a blade shell part of a wind turbine blade, comprising:
providing a mould for manufacturing a blade shell part of the wind turbine blade, the mould having a first moulding side with a first moulding surface that defines an outer shape of the blade shell part;
providing the blade shell part on the first moulding surface,
providing a support element and attaching the support element to a fastening section of the blade shell part, wherein the support element is a trailing edge flange, and wherein the attaching of the support element comprises applying adhesive between the support element and the fastening section;
providing an air heating assembly, the air heating assembly comprising:
a cover extending in a longitudinal direction between a first cover end and a second cover end and extending in a transverse direction between a primary cover end and a secondary cover end, the cover defining a cavity, the cover comprising:
a primary cover attachment section extending along the primary cover end; and
a secondary cover attachment section extending along the secondary cover end;
an air heater configured to provide heat; and
a tube comprising a first tube end and a second tube end, the tube being connected to the air heater at the first tube end and connected to a first opening of the cover at the second tube end;
attaching the cover to the blade shell part or to both the blade shell part and the mould such that at least the fastening section is enclosed by the cover; and
providing heat into the cavity by the air heater.
