This Simbrief Airframe is for the new updated Asobo B747-8 from Sim Update 13
i have done this airframe by myself and have been testing this and it works perfectely with the plane.
the links are in the file and there is 2 links, one for the PAX version and one for the freighter version although there is only one version of the B748 you can fly PAX and Freighter just because of different liveries.
