Hello,after updating to Build 640, the time changes for about ten minutes, when I click the buttom "Refresh AI Aircraft".It is not a big issue, as I can set the time ten minutes later when starting FS9.1, but I thought it is worth to mention.My best wishesHans-Christian

Hi,That is correct and that is the way we have always refreshed AI. But we had to bump it to ten minutes because at a lower value it wasn't working well. In the past it was a bump of 2 minutes.

Hi Jim,I see, thanks for Your response! My respect, ASE is working very, very fine now with FS9, I am impressed how ASE now handles the weather depiction in difficukt areas.My best wishesHans-Christian
