Mark thanks for your reply,

I thought this worked like this, however I was flying on KLAS & KLAX and on both approached the 3 cmd didn't start to burn. I already reinstalled the plain but still it is not working. Also setup my ILS frequency and runway heading. I normally use the first ILS do I maybe also set up the second ILS? Any suggestions for the solution or an airport where somebody is certain that the autpilot should work.
Please give me the airport and runway.

Thanks in advance.
