300/100/400 above/below your assined altitude

[alrot]

I forgot how is that we fix our barometric discrepancy with the ATC , in other words when I'm flight sometimes the ATC by IFR tells me that I'm flying  300/100/400 above or below assigned altitude

  I used to know to fix this a long time ago but I forgot

I keep pressing "B" to reset the altimeter and doesn't work :-/

Descend or climb by 300/100/400.....

I've never had them tell me that when I wasn't actually deviating or had the incorrect altimeter setting, what aircraft or is it for all of them?

Should be the "B" button like you said, check your settings/controls/  buttons/keys  /instruments:  and altimeter (reset) should have "B" assigned to it. I can't remember what I did one day, but somehow I messed up my control buttons on the key board and had to reasign them back to normal by using the defaults button.

An2dogs is right.
Alrot, the fact is that depending where you are flying, the barometric pressure changes and makes your altimeter display a wrong value. The ATC sees your real altitude though, and asks you to reach it.

In order to get the correct altitude displayed on your altimeter, you can:
- set the barometric pressure (there's a rotating button on some altimeters) according to the local meteo stations
- press the 'B' key to do that automatically.
You will see that, just like the ATC said, you are indeed below or above your assigned altitude.

One thing to note is that the adjustments of the barometric pressure are not necessary anymore above 18.000 feet, because from this altitude everybody has to use the same global setting.

Have you tried using another aircraft to see if it still does it?

I didn't see you post Stephane yes I keep dong it (not at this moment II'm busy I got to program my flight planer )
I'll do it tonight

  This is something that hapends as Daube said with the variation of the barometric pressure ,It happens to me most of the time in any airplane

  the weird thing is that the key "b" should fix it and its not doing it  :-/

When pressing the B key, what you should see if the altimeter(s) jumping up or down to the correct altitude.

I just want to ensure we're talking about the same feature here, so here's a bit of context: let's say you are flying at 5.000 feet exactely as planned in your IFR flightplan... 5.000 is displayed on your altimeter, but the ATC tells you that you are 500 below suddently. At this precise moment, it means that the altimeter is wrong. It shows 5.000 but you're not at 5.000. If you press B, you should see the displayed altitude change immediately to 4.500 feet. If you are with the autopilot, the plane should begin to climb automatically.

If the displayed altitude doesn't change, and the ATC keeps telling you're not in the correct altitude, then the B key doesn't work in your FSX.

One more thing... if the pitot tubes are frozen, the altitude display should get wrong too, right ?

that's exactly what is happening and its being happening since I bought the FSX

oh yeah ,maybe are frozen

[alrot]

Nope ,none of both No "b" (again) neither Heating Pitot tubes which in the 757 jetliners it display a sign in the Eicas screen
I took it from SVVA to

Go to the folder were your FSX.cfg file is. Open the Controls folder, and open the Standard.XML file using note pad and see if this is there:

The pitot tube is for airspeed.. the ASI measures pressure at the pitot tube, compared to pressure at the static port.. the altimeter works off the static port.. and I don't think FSX models static port ice.

You're using real-weather, right ?

Does the 'B' key set the altimeter to, '29.92' when above 18,000msl ?
