I am currently having an issue where after takeoff the aircraft is showing that I can only get to about 240kts before it gets to the red overspeed line and that will then disconnect the AP, I have gone through all my initial inputs setting up and all seems ok. Currently having to manage the AC at about 235kts to avoid overspeed.
This is the JARDESIGNS A320, XP 10.51, checked on JARS web but cant see this issue, all other things are running as expected, however when Autothruster gets above FL100 and wants to power on it cant because of the overspeed warning. If you need anymore info
