Does CBT include like a proper 3d flight sim environment, or is it just clicking on the right option/ECAM button page and popups?
If it's NOT the former, then damn, that's really surprising to me, since modern flight sim software (desktop, study-level) is quite advanced, accessible and well documented. Even the 'simulators' we used during the Pandemic for engineering were quite freaking advanced, in that, we had a proper 3d environment to work around in.
