Strange behavior with MCP

Hi all,

i use the PMDG 737-800 without panels and with the latest PM-updates. The CDU-Type is the 737-800 V4.

I expierence a very bad altitude capture in all speed modes. The A/C goes up and down about 700 feets when it reach the final altitude. It seems to be a Balance problem, but the preflight is set correctly and the CDU-File i modified with the correct A/C Data. The problem also exists with the 737-700 and other models.

I tried and payload values without success. The A/C swings up/down for long time before it captures the altitude.


Any ideas where to search?

Can I ask something stupid ?

Do you refresh your QNH (button B in FS9) when reaching final flight level ?

Did you accidently turn on the beta-autopilot which is under development by PM?

It is known that it has some problems in this area.
