Selected Heading - Garmin G1000:Socata Pilot's Manual

The Arc HSI is a 140˚ expanded section of the compass rose. The Arc HSI contains a Course Pointer,
To/From Indicator, a sliding deviation indicator (the To/From and deviation indicators are combined), 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 flag. 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).
