X-Plane doesn't take the 3D model into account for occlusion when rendering its lights, that's just the way it is. The same reason you see the sun shining through the cabin onto the displays and reflecting, it's as if the fuselage didn't exist.
One doesn’t need to do it by sight; any desync is ignored until you align your hardware with the plane’s throttle lever angle at the point ATS is disengaged. That’s why the overlay exists.
There are 3 lighting control panels at the rear of the pedestal. The brightness of...
.. is controlled by the right hand side integ lighting control,
.. are controlled by the centre, and..
.. are also controlled by their respective sides. No-one has reported issues with these controls before.
I believe that would be referring to the wheel well light, lights in the equipment compartments (not yet modelled), and so on. Not just one switch.
The checklists provided are an almost exact facsimile of a real world operator’s, for authenticity they haven’t been customised for the in-sim world.
I’m sorry to hear that, but as it’s not related to the Challenger I’ve moved this post.
This crash looks to be caused by the core sim and you should get in touch Laminar if it’s persistent. https://www.x-plane.com/support/
