HEADING (HDG) HOLD MODE, WINGS LEVEL
The basic lateral mode of the autopilot is heading hold. The heading
hold mode is defined as:
D Autopilot is engaged
D No lateral flight director mode is selected
D Bank angle is less than 6_.
When the three conditions are met, the autopilot rolls the aircraft to a
wings--level attitude. One second after the bank angle is less than 6_,
the flight guidance system (FGS) uses the current heading as the
heading hold reference. The primary flight display (PFD) annunciates

shows the autopilot (AP) and yaw damper (YD) on and the autopilot
altitude hold (ALT) and roll hold (ROL) modes engaged.
