Which knob is used to adjust the heading reference in HDG mode?

P-SYNC knob

NAV knob

Cyclic trim

HDG P-SYNC knob

In HDG mode, the heading reference is adjusted with the HDG P-SYNC knob. This control is dedicated to setting and synchronizing the heading the autopilot will hold. Rotating it changes the heading reference, and using the P-SYNC function aligns that reference to the current nose heading so switching into HDG mode doesn’t produce an abrupt, unintended turn due to compass drift. The NAV knob is for navigation source selection, not the heading reference; the cyclic trim is for rotor control trimming, not heading settings. So the knob labeled HDG P-SYNC is the correct control for adjusting the heading reference in HDG mode.
