I just got my PMDG expansion! Happy with it, except every time I start a flight; the CMD autopilot won't engage.My FD is on, all my generators, my FMC is happy, that F%$# thing won't engage for the life of it. I had to stop a flight because it wouldn't engage!The only thing I can think of is my yoke isn't in "Neutral Position"; but what the heck is "neutral position", and how are you supposed to put it in neutral position when you're flying with headings your supposed to turn to... altitudes that the ATC has commanded you to go to!??Is there a way to turn this off?Thanks, don't mean to dong PMDG; they did an excellent job, but it's frustrating!

and how are you supposed to put it in neutral position when you're flying with headings your supposed to turn to

Trim.

-Also; in the air my FMC said something about how it wasn't properly aligned... but I configured it correctly...

Trim.

... :(

Go into the configuration menus on the CDU and turn realistic autopilot engagement off. If it's a problem with the yoke not being centered that should fix it.

Thanks. I went into the FMC and loaded a panel state before takeoff state, and the CMD engaged; so it must of been a misconfiguration of mine.I'll just load that panel state when I want the autopilot to engage.

I see you solve the problem, but make always sure that your flight-director switches are activated!! Its required for the AP... And you loaded another panelstate, werethese switches were activated :)

Also try adding a small dead zone to your yoke axes if you choose to keep realistic ap enabled. It will make things much easier.

Neutral position is when your yoke is centred. The autopilot will only engage when the yoke is in this position (give or take a few degrees). You should only engage the autopilot when you're flying stable.
