CRJ-200 autopilot will not engage

[hawker800]

I wasn't sure where to post this - hopefully this is the right place.

 

I am Running X-Plane 10.25 64-bit and have been using the CRJ-200 for a while, without much trouble.

Recently however, the autopilot has refused to engage and I cannot figure out why this is happening.

 

The FD button enables the flight director and the command bars appear on the PFD.  Turning the heading knob selects a heading, turning the altitude knob selects an altitude.  So far so good. 

 

When I press the mode selectors on the MCP, nothing happens.  Visually, I can see the buttons being depressed, but the autopilot just ignores them.  Same thing for autopilot engage.

 

A friend also has the CRJ and it works fine on his machine - so I know I am not simply using the wrong technique.

 

Can anyone offer advice on how to fix this?

Are the Yaw dampers turned on?  That will cause the auto pilot to not engage.

No, it's not the Yaw Dampers.  A great suggestion though.  I tested it on my friend's machine and the symptoms are the same as I am experiencing.

Try reinstalling it see if that helps. Also a preferences dump is not a bad idea.

Reinstalling didn't fix it either unfortunately.

Do you mean dump the X-Plane preferences?  Or are there preferences specific to the CRJ?

I suspect you just have accidentally pressed AP DISC and have forgot to re-set it (by pressing the AP DISC bar back in).
