Garmin G1000 Pilot’s Guide for the Diamond DA40 190-00592-00 Rev. A2-16
PRIMARY FLIGHT DISPLAY
Arc HSI
NOTE: When the Arc HSI is displayed the BRG1
and BRG2 Information Windows and pointers are
disabled.
NOTE: If the pilot makes a heading change
greater than 105˚ with respect to the course, the
CDI switches to the opposite side of the deviation
scale and displays reverse sensing.
The Arc HSI is a 140˚ expanded section of the com-
pass rose. The Arc contains a course pointer arrow, the
TO/FROM indicator, a sliding deviation indicator (the
TO/FROM and sliding deviation indicators are one and
the same), and a deviation scale. Upon station passage,
the TO/FROM indicator flips and points to the tail of the
aircraft, just like the conventional TO/FROM flag. De-
pending on the navigation source, the CDI on the Arc HSI
can appear in two different ways:
• GPS, OBS, VOR – Arrowhead
• Localizer – Diamond
