sim/cockpit2/autopilot/heading_mode cannot be set?

[zoltron_rulez]

All,

 

I have the following dataref that I want to write but the value is ignored:

 

sim/cockpit2/autopilot/heading_mode

 

I try to write a value of 1 (int), but X-Plane ignores it. I tried writing to using dataref editor, same thing. How is this dataref set (for heading hold)?

 

**********UPDATE:

OK, I found out that I cannot write to this dataref, neither to this one (sim/cockpit2/autopilot/altitude_mode). Therefore, the question is, how do I control the MCP, what dataref, I cannot seem to find it.

 

Thx,

Thx Gregory, - I will give it a try. ********* Update: It worked.

P.s. Just spent reading info cmds vs datarefs from Ben's blog,- it answers a lot my questions.
