HORIZONTAL SITUATION INDICATOR (HSI)
The Horizontal Situation Indicator (HSI) displays a rotating compass card in a heading-up orientation. Letters
indicate the cardinal points and numeric labels occur every 30Ëš. Major tick marks are at 10Ëš intervals and minor
tick marks at 5Ëš 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 and is available in two formats (360Ëš compass rose and 140Ëš arc).
Changing the HSI display format:
1) Select the
PFD
Softkey.
2) Select the HSI FRMT Softkey.
3) Select the
360 HSI
or
ARC HSI
Softkey.
The 360Ëš 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.
