FLIGHT INSTRUMENTS
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. The HSI presents heading, 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 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.
