Figure 7-2: Partial Compass (ARC HSI)
The display is selected by pushing the MENU button and selecting
the HSI or HSI button if displayed. Use the HSI button to select the
360 HSI or ARC HSI.
The 360 HSI or ARC HSI compass displays consist of a compass
rose centered around the aircraft symbol. Aircraft heading is
displayed at the white lubber line triangle at the top of the compass.
Cardinal headings are labeled N, S, E, and W. Intermediate
headings at 30, 60, 120, 150, 210, 240, 300, and 330 degree
increments are labeled with one- or two- digit degree markings (for
instance, 060 degrees is 06, 330 degrees is 33). The short scale tick
markings are in 5 degree increments and the long ones at 10 degree
increments.
The 360 HSI display contains outer tick marks at every 45 degrees
except at the lubber line location. The partial compass display does
not contain outer tick marks.
The ARC HSI compass shows ±60 degrees from the current aircraft
heading.
