Thank you for your detailed answer!
I think I know what you're talking about now. Such a camera is constantly located at a certain point behind the aircraft. This camera is always pointed at the plane. Thus, this camera is completely stationary in the local coordinate system of the aircraft. This effect can be achieved by moving my second camera 10 or 15 meters back and 5 or 10 meters up.
I tried using such a camera in this game during its development. I did not like the intense background movement that naturally occurs with any angular movements of the aircraft. I note that this was only my personal assessment. And maybe it's too subjective. In general, there are many options for the camera control logic. And this topic I have yet to work out.
