GENERAL
The IG-832C Horizontal Situation Indicator (HSI) is an additional
navigation indicator option which provides a heading reference with
respect to an unslaved directional gyro, a heading reference bug, VOR
course selection, and a pictorial presentation of the airplane position
relative to VOR and localizer courses and glide slopes. This indicator is
used with Cessna 300and 400Nav
I
Comradios. Whendual Nav /Com radios
are installed, the HSI is coupled to the number 1NAV/COMand a standard
300 or 400 series VOR/LOC course deviation indicator is coupled to the
number 2 NAV/COM.
This system consists of a Horizontal Situation Indicator (HSI-Type
IG-832C) and a remote mounted VOR/LOC Converter (Type B-445A).The
indicator is unslaved and course datum is not available. When the HSI is
installed with a 300A,400Aor 400BAutopilot system, a Be light is
installed on the instrument panel, adjacent to the
IISI,
to alert the pilot of
back-course operation. Each control and indicator function is described in
Figure 1.
