FLIGHT INSTRUMENTS
The Arc HSI is a 140˚ expanded section of the compass rose. The Arc HSI contains a Course Pointer,
combined To/From Indicator and a sliding deviation indicator, and a deviation scale. Upon station passage,
the To/From Indicator flips and points to the tail of the aircraft, just like a conventional To/From indicator.
Depending on the navigation source, the CDI on the Arc HSI can appear in two different ways, an arrowhead
(GPS, VOR, OBS) or a diamond (LOC).

The selected heading is shown to the upper left of the HSI for three seconds after being adjusted. The cyan
heading bug on the compass rose corresponds to the selected heading. While the HSI is displayed as an arc, if
the heading bug is adjusted off the shown portion of the compass rose, the digital reading is displayed.
Adjusting the selected heading:
Turn the HDG Knob to set the selected heading.
Press the HDG Knob to synchronize the bug to the current heading.
The Selected Course is shown to the upper right of the HSI for three seconds after being adjusted. While the
HSI is displayed as an arc, the Selected Course is displayed whenever the Course Pointer is not within the 140˚
currently shown.
Adjusting the Selected Course:
Turn the CRS Knob to set the Selected Course.
Press the CRS Knob to re-center the CDI and return the course pointer to the bearing of the active waypoint or
