Well, in that case I do not understand why you say ... : "If you leave the autothrottle off in a 777, it is sort of "more demanding" to manually fly the airplane, because you have to compensate for the autotrim system in a way that you have never done on another a/c type before. It is "an annoying way of flying". It can be done though. But you have to be aware of the little details"
I fly the Airbus A/P and A/T off on most of my approaches and the fact that you do not have to trim is not problem whatsoever, on the contrary. Coming off B737 before joining the airbus fleet, it took me exactly 30 seconds to get used to that!
So if you say that "the 777 autotrim function works in a similar way as on the Airbus. It prevents pitch changes by staying in trim, I then do not understand why it would be "more demanding" or "annoying" to fly the 777 manually without A/T rather then when leaving the A/T thrust on.
