with altimeter set to 29.92 at runway altimeter reads 230’ , that is incorrect.

No, if the ATIS reports 30.12 (as described in your original post) and you set 29.92 230' sounds about right - as proven by setting 30.12 and reading 420' (KSEA elevation is 423')

The altimeter reading in KSEA right now is 30.18

What runway are you at?

16L for my test.

But it could be any runway.

The altitude Difference (29.92 and current ATIS Baro altitude setting at the runway) will be the autopilots armed climb altitude (3000 feet plus the error) .

No it couldn't. Depends at what end of which runway you are located.

Seattle has each runway at a different elevation.

So it advises on the Chart thus; (Apt Elev See Graphic)

And on consulting the Graphic you will see individual elevations of each runway thus;

So that would be about correct as the other end; 34R is nearly 100' lower.

Ok,

Now do the departure and fill in your numbers using in my first post as a guide and see if anything is incorrect?

16L at KSEA with 30.18 set in Kolsman window,, the altimeter should read pretty close to 434 feet.

Pick any runway and do the climb test out of KSEA.

Results?

Fill your own numbers in and stop subcontracting out your own confusion man!

Yes, that is what I was originally asking you for.

Now do the MSFS KSEA test flight per my first post and show you numbers.

Yeah, pretty sad, frankly. He avoids answering any question that he doesn't understand. Up is down....LOL

the post I did is as mentioned a example. Did I mention example in my first post?

Do your test flight and see if the climb to altitude is correct or not.

Do some reading and then do your own test flight.

My test was an example. I mentioned I used RWY 16L KSEA.

You can do your own test and record your own results.

What altitude did you stop at on your test?

We are trying to tell you to learn how an altimeter works. You want us to tell you how to write a book, and you don't know the alphabet.

In my test example I am simply showing a 190 foot difference with MSFS at the runway.

Then doing a departure to 3000 feet and see where MSFS stopped.

190 feet too high.

Now on your example flight check the difference and depart.

What altitude did you stop at?

I am reporting what I see with MSFS.
