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 is available in two formats, a 360˚ compass rose and a
140˚ arc.
Changing the HSI display format:
1) Press the PFD Softkey.
2) Press the HSI FRMT Softkey.
3) Press the 360 HSI or ARC HSI Softkey.
The 360˚ 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.
