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. 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) Select the PFD Softkey. 2) Select the HSI FRMT Softkey. 3) Select 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. 17 16 15 1 2 14 3 13 4 5 12 6 11 10 7 9 8 1 Turn Rate Indicator 2 Selected Heading 3 Current Track Indicator 4 Lateral Deviation Scale 5 Navigation Source 6 Aircraft Symbol 7 Course Deviation Indicator (CDI) 8 Rotating Compass Card 9 OBS Mode Active 10 To/From Indicator 11 Course Pointer 12 Heading Bug 13 Flight Phase 14 Selected Course 15 Turn Rate and Heading Trend Vector 16 Current Heading 17 Lubber Line Figure 2-15 Horizontal Situation Indicator (360˚ HSI) 56 Garmin G1000H™ Pilot's Guide for the Bell 407GX 190-01255-00 Rev A
