I've noticed on both the 747-400X and the Dash 8 that I can't get the airplane to fly the heading set in "heading select".  Flew the 400 in FS9 for many years and that was never an issue but not so in FSX.  Any ideas?

 

Thanks in advance.

 

 

Should work fine.

 

Problem must be at your end.

 

Is the flight director commanding the correct heading?
