RDY (Ready)
Illuminates when the autopilot is ready for engagement. When the airplanes
Master Switch, Avionics Bus Switch and the Autopilot Master Switch are
turned on and the rate gyro RPM is correct, the RDY annunciation will be
shown indicating the autopilot is ready for the functional check and operation.
The autopilot cannot be engaged unless the RDY annunciation is shown and
the G1000 initial AHRS alignment is complete.
HDG (Heading) Mode
When HDG is selected, the autopilot will engage the HDG mode, fly the
airplane to, and hold the heading set on the HSI. For the smoothest
transition to HDG mode, it is recommended that the airplane be aligned to
within 10° of the selected heading before engaging HDG. The HDG mode
is also used in combination with the NAV mode to set up a pilot selected
intercept angle to a course.
GPSS (GPS Steering) Mode
When navigating using GPS, pressing NAV twice will cause the autopilot
to enter GPSS for smoother tracking and transitions between waypoints.
When GPSS is selected, the autopilot computer receives ground speed
and bank angle signals that are calculated and converted to a commanded
turn rate. The turn rate is then scaled and converted to a DC heading error
signal that is compatible with the autopilot. The end result is an autopilot that
can be directly coupled to the roll steering commands produced by the GPS
Navigation signal.
REV (Reverse Course) Mode
When REV is selected, the autopilot will automatically execute high
sensitivity gain for an approach where tracking the front course outbound
or tracking the back course inbound is required. The APR and REV
annunciations will be shown on the G1000 and the autopilot computer when
REV is selected.
APR (Approach) Mode
When APR is selected, the autopilot provides increased sensitivity for
approaches.
