Horizontal Situation Indicator - Garmin G1000 Pilot's Manual

HORIZONTAL SITUATION INDICATOR

The Horizontal Situation Indicator (HSI) displays a
rotating compass card with letters at the cardinal points
and numeric labels every 30 degrees. Major tick marks
are at 10 degree intervals and minor tick marks are at 5
degree intervals. The HSI is displayed in a heading-up
orientation. The HSI compass can be displayed as a 360°
rose or a 140° arc by pressing the PFD softkey, followed by
the 360 HSI or the ARC HSI softkey. The HSI displays the
following information:
• Heading indication
• Turn Rate indicator
• Course Deviation Indicator
• Bearing pointers (360˚ HSI only)
• Bearing information windows (360˚ HSI only)
• Navigation source
360˚ HSI
The 360˚ HSI contains a course deviation indicator
(CDI), with a course pointer arrow, a TO/FROM arrow,
a sliding deviation bar and scale. The course pointer is a
single line arrow (GPS, VOR1 and LOC1) or double line
arrow (VOR2 and LOC2) which points in the direction
of the set course. The TO/FROM arrow rotates with the
course pointer and is displayed when the active NAVAID
is received.
