Modes of Operation

LATERAL MODES

Heading Hold Mode

The basic autopilot lateral mode is heading hold, defined as follows:
D
The autopilot is engaged
D
No lateral flight director mode is selected
D
Bank angle is less than 6_.
NOTE: Basic autopilot modes
When the three conditions are met, the autopilot rolls the aircraft to a
wings–level attitude. The heading hold mode is not annunciated on the
PFD because it is the default lateral mode when no other lateral steering
mode is selected.
Figure 6–1 shows a PFD in heading hold mode. No command bars are
displayed until a flight director mode is selected.
