The clearly know what is not correct with this airplane. Lots of reports relating to the Vnav speed management etc. I see the same issues on the 757 and that aircraft have been on the market for a while without any attempts to fix this basic Boeing FMC management. I like realism and the simulation should get the basics correct as a minimum.  It has potential, but it is far behind when it comes to correct speed management and accurate and precise flight path management.

For sure lots of things to be fixed with VNAV, I posted VERY detailed issues yesterday on the bug forum. They've acknowledged and thanked me for the reports and said they're working on it. We will see my friend!
