I'm getting same problems...
Rshift Home doesn't work anymore.
When you press RAlt-Home to start left engine, now you notice APU start up first and after that is done the left engine spools up to start. Then once that is done, you are allowed to turn on the right engine. I'm seeing some similarities to the A-10C. However, attempting to start right engine first will not allow to start the left engine after. (Which is fine...left engine is usually first)
I have no idea how to ARM the EAC, so no way to have autopilot from a ground start. (EAC is set to arm from an airborne start allowing Autopilot use)
The autopilot seems to now be having the similar limitations to A-10C which is nice (such as only engaging when you're near straight and level flight), however as mentioned earlier I've only been able to use it if I start airborne already, it will be by default in ALT/HDG mode...with LAlt-2 I can switch it to ALT only, BUT I have not found a way to switch it back to ALT/HDG mode after that.
