Good evening,

Yes - I am a school student.

By the way, a pilot told me that trim is not available over 1.3G and below 0.3G, confirmed by F-COM.

Well, let me recap for vertical side-stick movents - please correct me If I am wrong.

When we pull the stick, we basically tell the computer how fast we want to increase/decrease pitch, also called G Load.
If my pitch angle is NOT increasing/decreasing, then I am at 1g. To maintain any G above/under 1g, the plane will have to keep increasing/decreasing pitch.
So stick is saying (e.g) it want's 2.5g. That is equal to the fastest pitch-up demand. So lower the G, lower the speed at which pitch will increase.

In the Airbus FBW system, you have pitch angle protection = 30° Configuration Clean.
So at a certain point, you will not be able to increase G, as the pitch angle will no more increase. It means that you will be at 1g.*

Now you also have pitch trim - it maintains the current aircraft's pitch at 1G.
It doesn't work over 1.3G and under 0.5G. But even if you release the stick, with a G > 1.3G, the aircraft will maintain the current pitch angle because it would have gone back to 1G (Aircraft is no more pitching).

AoA has the priority. The plane can hit Aprot at a low pitch angle.

Am I right?

Thanks a lot,
