PMDG 747 FS9 Autopilot CMD Problem

Recommended Posts



At first time, sorry for my bad English.


My problem is that the button CMD (al 3 buttons) not engage. I can engage Autothrottle, HDG, Alt Hold, etc but is not posible to connect the CMD. 


I am using B744 on FS9 and I have installed the PMDG 737 too. The B737 works fine.


AMD Phenom II X4 955 3.2 GHz

4 Gb Ram

Radeon HD5750

Windows 7 64 Pro


CH yoke and pro pedals

VRInsight MCP II Boeing


Please, anybody help me?


Thanks and best.

First, your English is very good.


Is your FS9 patched to version 9.1 ?


Did you install the 737 first, then the 747 ?


Have you tried unplugging the CH yoke/pedals and your VR insight panel. Then load FS9 and try a flight. You will have to use keyboard to rotate the aircraft and try engaging CMD above 400 feet. This will establish if your hardware is causing the problem.
