Thank you all. I have been flying Sim Airbus's for decades and never knew this and this I believe is the first Airbus I've flown that wont let you trim. (or at least makes it difficult to)

Me too, this auto trim function never happened with any other FSX or P3D or even MSFS FBW models, I always set the trim before takeoff and while flaring:).......Good to now I was wrong for years.

Also I have to mention that, at my previous attempts to enter the TOCG produced by EFB, I found that it was tuned automatically. I was surprised and thought it's a coincident but I had doubts that the trim was set automatically. 

I can use the controller bindings for elevator trim in the same way in the Fenix as any other MSFS plane. I usually set it during engine start, when the trim information become available on the MCDU INIT B page.

The lack of the need to trim during flight is one of the reasons what makes the A320 so easy to handle. The 737 seem to require considerable elevator trim input after changes in pitch or thrust.

I think on the A330 this actually sets the aircraft trim and the crew doesn’t manually adjust it before takeoff.

On the A330 the pilots also set the take off pitchtrim manually with the trimwheel. However there would be a warning (maybe when pressing take off config test switch, can‘t remember exactly) if the trim wheel setting and the trim value on the MCDU PERF page differ too much (as far as I can remember this is on the enhanced A330 only, not on the classic versions, could be also part of a flight warning system FWS modification).

However you are right, on the A320 the PERF page value is merely a reminder.

I remember reading somewhere that entering the trim in the perf page on the A320 doesn’t actually do anything but simply serves as a reminder to the crew.

It also forces the plane to check trim position vs. the MCDU input, so if you have it say set to DN 1.0, but the MCDU input us UP 1.0 it will give you a config warning when you test takeoff config or advance the throttles.

So yeah a reminder, but it's wired a little bit into the software as to give you an actual *reminder*
