TRK
In this mode, the roll axis will fly the selected GPS ground track via the TRK (track) bug.
The TRK bug value is not synchronized unless you manually synchronize the TRK bug or utilize
Control Wheel Steering (see section below for detail). This allows you to pre-select headings in
an IFR environment before you want to actually fly to them.
NAV
In this mode, the roll axis will track the selected HSI source from a GPS, VOR, localizer (LOC) or
GPS roll steering (GPSS).
If the HSI CDI is not already near-centered, NAV mode will be armed, not immediately
activated. The pilot then manipulates the autopilot via TRK, HDG, or Roll Hold mode to
command an intercept of the HSI course guidance. As the CDI centers, the autopilot will
automatically sequence and activate NAV mode.
When the autopilot mode sequences, the autopilot annunciation in the top bar will blink for 10
seconds.
When your HSI source is a radio-based VOR or LOC, SkyView uses GPS position
information to help the autopilot correct for wind effects. If no GPS is available to
SkyView, VOR and LOC sources can still be flown by the autopilot, but the
autopilot’s ability to perfectly track the course guidance may be reduced.
Roll Hold
In this mode the roll axis will fly the target aircraft roll angle. The roll target is the current roll
angle of the aircraft at the time roll hold is activated. The roll target can be adjusted with
Control Wheel Steering (see section below for detail).
