I have to say in some way i do agree with 7478ti. After switching to the airbus i sometimes missed the in-between way of dealing with slow or non-behaving autothrust on boeings. If it is to fast pull it back a bit and then let it continue on its own, or push it forward somewhat and then let it continue on its own.
On the bus i have to disconnect it completely, after i have to sync the thrust levers to the current thrust level first. It is somewhat more cumbersome. Interestingly enough 99% of us do fly (nearly) always in manual thrust when in manual flight as a result of that. In fact, some have to do the odd autothrust on approach to keep current in this kind of operation. It is just much easier to fly manually in manual thrust, but that is of course my personal opinion. Even manual thrust in automatic flight sometimes works better than both in automatic.
