Can you explain how does it compensate for thrust changes.
Two different effects with thrust changes:
* Pitch/power couple is almost entirely removed through software on a fly-by-wire aircraft.
* The 777/787 will pitch to maintain airspeed with a power change - add power, pitch will gradually increase to maintain the trimmed speed and vice-versa. An Airbus (with plain old C* law) will maintain flight path at the expense of speed until another limit in the flight path envelope is reached.
Personally I prefer the stability of the Airbus - on a gusty day with significant speed changes the flight path on approach tends to be nailed. Speed changes on a Boeing result in flight path changes.
