Horizontal Situation Indicator (Hsi) - Garmin G1000 NXi Pilot's Manual

HORIZONTAL SITUATION INDICATOR (HSI)

The Horizontal Situation Indicator (HSI) displays a rotating compass card in a heading-up orientation. Letters
indicate the cardinal points with numeric labels every 30˚. Major tick marks are at 10˚ intervals and minor tick
marks are at 5˚ intervals. A digital reading of the current heading appears on top of the HSI, and the current
track is represented on the HSI by a magenta diamond. The HSI also presents turn rate, course deviation,
bearing, and navigation source information.
The HSI contains a Course Deviation Indicator (CDI), with a Course Pointer, To/From Indicator, and a sliding
deviation bar and scale. The course pointer is a single line arrow (GPS, VOR1, and LOC1) or a 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.
A digital reading of the current heading appears on top of the HSI. A magenta diamond on the HSI represents
the current track over the ground the aircraft is flying. To the upper left of the HSI, the Selected Heading is
shown in cyan, which corresponds to the cyan heading bug on the compass rose. The Desired Track (DTK)
is shown in magenta to the upper right of the HSI when the selected navigation source is GPS and OBS Mode
