Radio Flyer
Part 2
The Malibu Mirage and the Navajo Chieftain both use the
same excellent AlliedSignal - Bendix/King radio equipment as the
Cessna 172R. Operation of basic nav, comm, transponder, and
ADF equipment is exactly the same, but the nav displays use more
sophisticated instruments. In addition, depending on airplane,
some additional equipment and capabilities have been added.
HORIZONTAL SITUATION INDICATOR (HSI)
This may well be the coolest single
instrument you’ll encounter. First devel-
oped in the 1960s (and called a Pictorial
Navigational Indicator at first), the HSI
combines the functions of a gyrocompass
and a nav indicator (with OBS, CDI, and
flags built right in) to give you a “God’s-
eye-view” that lets you see and interpret
your whole navigation, or horizontal situa-
tion at a single glance.
Here’s how it works. The outer ring, calibrated in degrees, is
a gyrocompass. As with the conventional directional gyro, it rotates
as the airplane turns, with your heading always shown under the
line (called the “lubber line,” a throwback to the days of iron men
in wooden ships). Compared to the standard gyro, however, it has
an added feature: you don’t have to set it every ten minutes or so to
compensate for instrument drift. Instead, a small magnetic sensor
mounted elsewhere in the airplane (usually in a wingtip or in the
tail to get it away from all the steel in the engine) constantly corrects
the system for drift, so it points accurately to magnetic north at all
times.
