INDEX
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 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).
