Isn't there realy anyone who have heard about this problem.I know the alarm IRL, comes when there is a altitude disagreement on more than 300 ft. between capt.and fo's display, but that is not the problem here.Please help us.Ole D.

i dont think someone is setting the altimeter to a difference of 10000 feet. do you notice anything else that is unusual? do you guys have some weather addon? describe a bit better whats going on there,.. what route, how do you proceed?

1. yes, the altimeter is set correctly. - both of them. 2. Everything seem to be working correctly untill a litlle after start, - I didn't notice the high. Then the message "alt disagree" appears in yellow in the PFD display in the botton of the alt. tape, and the altimeter (in the PDF) starts to move very slow. It seems that the stand-by altimeter is showing the correct altitude. In about 400 feet, I engage the autopilot and the plane is increacing the altitude, I gues the autopilot is following the PFD altimeter, cause it don't stop when reacing the altitude set in the MCP.I've been flying both off- and on-line. I tried with severel different flight planes.I hope this can give you a hint about something. Praying.gif Ole D.

I am having problem with PFD. Cruising FL330, TOD no descent, Then found standby altimeter showed 25000 and descending. Had to select 2D cockpit then back to VC to get reading. This in the NGX. Problem now occurring in the 744 PMDG. Looks like same problem as Andy above.

You'd be surprised.
I think you must be setting the record for most posts in a given time - averaging 54 a day! Beats my 0.06 or so! lol!

Hello, Try setting the units of measure parameter in the General settings of FSX to U.S. System I had the same problem and found out that Capt PFD displayed altitude in meters but the F/O in feets. I hope it helps,Balázs Patyi

you just need to look closer at the altimeter.. The thousands unit is directly on top of the rectangular box around the hundreds values...It might be a video aspect issue. maybe..

IS anyone using the Hotfixes? At this stage I am not, so as not to confuse the issues.
Might be why you're seeing some freeze in the panel; the hotfix addresses this.

As already stated, go into the settings of FSX and change away to IMPERIAL. I thought I was on imperial as well untill I got this aircraft. There is 3 settings in there if I recall correctly Metric, Imperial and a sort of mixed up one. I was on the mixed up one. If you notice, when your altimeter says 1000 you are actually at 3280feet. There are 3.28 feet to the metre.

The original post in this thread. However I did mostly skim over it and missed the part about the alt disagree..

Alternatively did you by any chance accidently click the switch that changes between metres and feet. its just to the left of the subscale knob if I recall correctly. There are other options in the PMDG part of the FMC related to altimeter setup I think.

I think I would have noticed that. If you read my post the altimeter in PFD is frozen while the standby alt is working

Hi Delta, I was directing my advice to the OP and anyone else that might have problems with this aspect of the sim, obviously this would not apply to you.

Glad your sorted. When it happened to me on my first flight I thought I had some sort of static pressure line problem! And I was thinking, wow this is one hell of a good sim!
