Depressing either control yoke trim switch will also disengage the
autopilot.
ST (Stabilizer) Mode
- Turning the Mode Select Knob left or right in
ST (Stabilizer) mode will provide left/right steering commands to the
autopilot proportional to the knob displacement. Steering command is
limited to a standard rate turn maximum.
HD (Heading) Mode
– When HD is selected, the autopilot responds to
heading changes made using the HDG knob on the DG or HSI. If the
airplane heading is within 5° of selected heading when the mode is
selected, the autopilot will turn the airplane to the heading and then
follow the heading. Subsequent heading changes can be made using
the HDG knob on the DG or HSI.
TRK (Track) Mode
– When TRK LO is selected, the autopilot will
provide low system gain for comfortable cross country tracking of GPS
or VOR courses. When TRK HI is selected, the autopilot will provide a
higher level of system gain for more active tracking of GPS, VOR, or
Localizer front course signals.
ALT
(Altitude Hold), mode and the
TRIM UP,
and
TRIM DN
annunciators are not functional with the System Twenty Autopilot.
Flag Window
– A red flag indicates insufficient electrical power (less
than 24 VDC) to the Turn Coordinator rate gyro. The turn coordinator
has its own backup power supply.
