AFAIK even the B777/787 has autotrim for thrust and configuration changes. Even the speed stability is artificial: Basically the control laws are the same as on the Airbus, with a function that chases airspeed put on top if it? Is it true that for speed changes you don't have to actually trim, but only briefly hit the trim switch in the correct direction and then it will trim automatically for the current speed?

I've always wondered what autotrim is good for. I mean, trimming is not that difficult, is it? You do it with your thumb, instinctively, mostly subconsciously. But it gives you a feeling for your airplane, how it naturally reacts to thrust and configuration changes etc. Through everyday practise, that knowledge will be more than just learned and trained, it will become engraved into your mind and you will be able to apply it without actually having to remember and think about it. There have been occurences in which pilots brought a crippled airplane back under control by lowering gear, using thrust, extending flaps etc. They did that intuitively because they knew how their plane would react to this. Would pilots that never trim their airplanes outside the sim be able to do that?
