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 30˚. Major tick marks are at 10˚ intervals and minor
tick marks 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 bug. The HSI also presents turn rate, course deviation,
bearing, and navigation source information and is available in two formats (360˚ compass rose and 140˚ 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 360˚ HSI (Figure 2-14) 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.
