In the spirit of continuous learning, I’m sharing a podcast on the A320 that you may find interesting. I’m making my way through episodes now and it’s a great place to learn all aspects of the A320 in 20-30 minute podcasts. Episodes started in 2016 right up to today.

how to reset all data of mcdu after a flight?
Back to the main menu and start a new flight session.

You have to enter a new route. And it will erase everything from previous flight.
Just the code of the 2 new airports. But then, you will have to put in manually, all info (waypoints) of next flight. Impossible to just import from saved .flt or .pln.
But it’ll be more realistic too

The certified maximum operating altitude of the A320NEO is 39800 feet. That is the maximum altitude at which it is possible to maintain the cabin pressure altitude below 8000 feet. The airplane must be operated in accordance with its operating limitations.
Selected mode (open climb or open descent) does not in any way user the climb/descent “profile” in the MCDU. It simply use climb thrust for climb and idle thrust for descent and uses pitch to try to maintain whatever speed you have set in the FCU. The climb or descent profile simply falls out from that.

When landed, I’ve input new ICAO of depart/arrival, but when input waypoints, it was impossible. It said that AWY /WPT MISSMATCH despite any waypoint. And It said that ENTRY OUT OF RANGE when I input crz fl in INIT page (I have tried to input FL360, 360…value). I’ve installed latest of FBW dev version and going to retry after working.
Did yoy try first to re-align the Adirs ??
How to re-algin Adirs, @Skandinavian941
You are right, the A319 and A321 are certified up to FL410 I believe, A320 is 39200 or 39800 or something depending on some mod installed.
Of course you shouldn’t climb above the maximum certified altitude in real life, problem still remains that the default MSFS A320 is seriously underperforming, not even able to reach optimum altitude according to the QRH.
Also there is no special authorization required to fly above FL400, at least in European airspace.
I agree with your last sentence. I was responding to the question you had in the comment I responded to - “What certification do you need above FL400?”
Yeah, that’s what I meant… The airspeed set in the CLB or DES phase in the MCDU PERF pages.
Turn the three ADIRS switches on the overhead to off.
When the nav display goes black, turn the switches back on.
Wait for alignment to complete before moving aircraft.

Should not be necessary, you normally don’t realign IRS / INS / ADIRS during turn-around. Maybe check and update the IRS position via the MCDU between flights but nothing more.

Apparently, you have to shut the FCDU down to clear the data from it, if you want to continue another leg from the airport you landed at.
MSFS won’t allow to input after you land from your first leg.
This was suggested as a means to do that.
I’m using FWB mod, after finish a route and landing, I turned off ADIRS and turn on to reset alignment. After input new route and waypoint, I started to flight and a320nx did not follow flight plan, what happened? I dont understand
There is so much wrong with the Airbus, in real life changing origin / destination will clear the current flight plan and you can create a new one without the weird errors. I haven’t flown the Airbus in real life but I have flown with Thales FMCs, its the same thing. But like with everything, what works in real life does not necessarily work in MSFS

Unfortunately, the MS series of flightsims never supported multi-leg flights.
What you are doing by re-aligning is overcoming that limitation, however, it seems that is not the only thing that needs to be done to be able to fly more than one leg.
I’ll see what I can find.

so disappointed…

I think the whole route system is overcomplicated, the route programmed into the FMS / GPS is not just the route for the aircraft to fly, somehow ATC has a glass sphere and uses the route programmed into the FMS / GPS as your “filed” ATC flight plan.
They should have separated those two, the ATC flight plan is what you create in the main menu or some flight planning widget whilst in the game, the route the aircraft is actually following is what you enter into the FMS / GPS with some transfer option to automatically load the “filed” ATC flight plan into the FMS / GPS for people who don’t want to manually set-up the FMS / GPS…
