As we know, the second and third columns of the FMA indicate the currently engaged or armed vertical and lateral guidance modes. These indications should remain visible as long as either the autopilot (AP) or flight director (FD) is active. However, in the iniBuilds A350, the vertical and lateral guidance modes disappear from the FMA when the FD is turned off—even if the AP remains engaged. As a result, there is no way to know how the autopilot is attempting to fly the aircraft, as if it's in some kind of "God-knows-what" mode. This behavior is clearly incorrect.
