Unfortunately, as you say, I believe this will be a limitation of using Chaseplane with some of our products. The Vulcan, and a few of our other products, rely on the core MSFS camera system to move the user to certain locations in and around the aircraft. As Chaseplane overrides the default camera system, the cameras that we trigger in the code no longer exist, so the camera will not change.
It's something we have logged on our internal trackers for further investigation, and to see if there is any form of a workaround we can find for Chaseplane users. In the meantime with the Vulcan, it should be possible to create custom Chaseplane cameras inside the AEO/Navigrator compartment and then trigger those via the Chaseplane interface.
