AUTOMATIC FLIGHT CONTROL SYSTEM
HEADING SELECT MODE (HDG)
Heading Select Mode is activated by pressing the HDG Key. Heading Select Mode acquires and maintains the
Selected Heading. The Selected Heading is shown by a light blue bug on the HSI and in the box to the upper
left of the HSI.
CHANGING THE SELECTED HEADING
NOTE: Pressing the HDG Knob synchronizes the Selected Heading to the current heading.
The Selected Heading is adjusted using the HDG Knob. Pressing the CWS Button and hand-flying the
aircraft does not change the Selected Heading. The autopilot guides the aircraft back to the Selected Heading
upon release of the CWS Button.
Turns are commanded in the same direction as Selected Heading Bug movement, even if the bug is turned
more than 180° from the present heading (e.g., a 270° turn to the right). However, Selected Heading changes
of more than 330° at a time result in turn reversals.
