According to the FCOM v2 page 11.43.10:

"Until an arrival approach has been selected into the active flight plan, the destination airport altitude is used by the cabin altitude controller."

 

I didn't know that the landing alt message was triggered when an approach was not selected though. I always fly with an approach selected.

 

OK. Thanks a lot for the "start-up" help to all of you.

 

My main Problems are solved. Now I can RTFM   :-))

 

thanks and bye
