Concours77, be very careful of home grown definitions in the broader context of modern aviation.
Before you can understand the Airbus FBW flight control laws, (and the AF447 accident) you should understand C* flight control and how it operates.
Similarly, to understand Boeing FBW flight control laws, it would help to understand C*U flight control.

So how do you think we trimmed the F-4 Phantom with a single all moving stabilator at the back end and no elevator or trim tabs and electricity only needed to change the trim setting? When you understand that, you will understand that your trim definition is impossibly restrictive.

The tab is cranked in to establish a "trimmed" aspect for cruise.
