Hello PMDG team I have reinstalled my MD 11 - fs9 after pc problemsand now When I am in climb , cruize the speed is limited to 320 knots ? unable to go faster ? even if in the fms page PERF here I have for example 350 knts setted for the flight ? I have red strips that limit the speed to 320 knts ? on the speed tape ? unable to unlock that ? Also in the descent the FMS speed do not follow the fms speed which is setted for ex to 320 knts policy descent ? Any advise to solve that please ? something to set somewhere ? cfg ? etc .......Thanks regardsPatrick

Posting a screenshot might help.

HelloWas with 30 % fuel and every flight , every altitude before to install the update ? Thanks regardsPatrick

Vmo/Mmo is a function of the amount of fuel in the wingtips. There was a post on this topic a few weeks ago. I'm sure it's covered in the manual, but briefly, the less fuel you have, the lower your Vmo will be.
