FBW, trim
Just to be absolutely clear, with FBW you can never fly it completely "like" a non-FBW aircraft. There is simply no physical linkage there to fall back to. There is only a wire (wiring) electronically communicating intended control movements to control surface actuators.
Of course in Direct Law the intention is that pilot inputs are directly and immediately communicated as-is to the actuators. (And maybe that is what was meant by "like" above.) But technically it is still a simulation of a direct physical link (something like controlling avatars in video games).
Not that there is anything wrong with that, by any means. Just that it is different. With differing failure modes, for instance.
