Heading BUG

[asnamara]

Hi Everyone ,
When I want to set the heading, I use the Heading Knob in the center console. It changes the left one but not the right one. What am i doing wrong. Could not find anything in the manuals.
Regards,
Amara

It only controls one side at a time, and that side is whichever Flight Control Computer is currently set at the AP source.

From page 63 of the manual:

The heading rotary knob is used to adjust the heading reference bug for whichever Flight Control Computer (FCC) is currently selected as the autopilot source with the “AP XFER” button on the Autopilot Panel (APP). Pressing the center of the knob will synchronize the heading reference with the aircraft’s current magnetic heading.
