Wow, this has been an excellent discussion. I enjoy reading it as it also highlights areas that I might edit the article to make it clearer or answer questions in advance. If anyone has such suggestions, I am always interested, for this, or any of the other articles. I strive for accuracy.
I did add a couple of points to it regarding flight controls, particularly the issue of how FBW system envelope protection features might come into play, as well as the consideration of their architecture for alternate control strategies. The UPS 6 crew lost most of their elevator control due to the fire, but the autopilot is FBW, for example...
Anyway, take a look at the article again for these additions and, again, I welcome suggestions and additions if you have any thoughts on that. You can post them here to continue this discussion (these types of discussions can save lives), or to the contact info on the blog. - Thanks!
