As far as I know, flight envelope protection (not to be confused with FBW) has been introduced with the E2, and at least in the E1, the FCM cannot override any pilot input, and I’m curious if the FCM can override any pilot input in the E2. I don’t know the exact differences between the 3rd gen FBW (E1) and the 4th gen FBW (E2), but to me it sounds like Embraer is not marketing the new FBW as a minor change, and that they’re not marketing it as a major change. To me it sounds like Embraer is marketing the 4th gen FBW that is in the E2 like a ‘medium’ upgrade compared to the 3rd gen FBW that is in the E1.
I also think that what Embraer is marketing as a medium upgrade in my opinion could be a minor upgrade in reality, because it’s marketing. I do understand that cockpit commonality is very important.
Important edit:
I’m not denying any facts, I have questions about the E2, and even though nobody said I’m denying facts, I just want to make this clear before anyone thinks I’m doing it.
