Dozywannabe,
The engineering in modern airplanes, as well as the software technology, is truly amazing.
Nevertheless, "traps" like those recognized elsewhere in this forum (for instance, in differences between autothrust lever engagement and movement between Airbus and Boeing) are becoming better known as operational experience increases.
Years ago, I attended an aviation psychology symposium at Ohio State University, when "FBW" and automation by Airbus was still in the development stages, and FBW was still markedly controversial.
One of the speakers said that the software was very complex, having to contend with untold combinations of conditions (such as which warnings to inhibit on the takeoff role, to prohibit rejected takeoffs for non-critical events). Inevitably,he speculated, automation would act "unreasonably" and cause problems in some unforeseeable situations.
Keep alert. Expect the unexpected. Your turn could come tomorrow.
