Hello @Merrtsa, this question has already been asked on other occasions and answered:
No, it was never in the plans to make a 2-seat and hardly we’ll change our opinion. Making a 2-Seat version would require increasing the geometry to include the co-pilot cabin and elements, as well as duplicating the current digital screens, and this would greatly compromise performance. Especially on Xbox, when not only with this plane, users experience black avionics problems in combination with other mods or when passing through airports with high gpu load. If in the future it were guaranteed that these problems would not occur I would consider the possibility, but in the meantime, no.
Best regards.
