CHAPTER 1 WELCOME TO THE SN3500 EHSI
What is the SN3500
For years, pilots of large commercial aircraft have appreciated the
benefits of Electronic Flight Instrumentation Systems, commonly
known as EFIS. Full EFIS systems combine data from different
sources within the aircraft and provide the pilot with a unified
display. This greatly simplifies the instrument scan and improves
situational awareness.
The Sandel SN3500 Electronic Horizontal Situation Indicator, or
EHSI, packs the essential features of an EFIS NAV display into a
standard three-inch instrument, but at a fraction of the cost of a
traditional EFIS. By combining the functions of an HSI, an RMI, a
moving map and a Stormscope® display into one instrument, the
SN3500 ties together the critical elements of situational awareness.
And by adding to that a 3-light marker beacon and GPS annunciator
displays, the SN3500 becomes the virtual equivalent of an EFIS
NAV display, sized and priced for general aviation cockpits.
The SN3500 EHSI uses Sandel’s patented rear-projection display
technology. This technology allows the displayed image to extend
to the edges of the instrument’s bezel. This provides an image
approximately the size of a four inch primary display in a three inch
form factor.
Internally, the SN3500 uses high-speed digital converters that allow
it to receive signals from virtually every type of navigation receiver
ever installed in general aviation aircraft. A comprehensive set of
maintenance pages allows the installer to simply specify the make
and model of the installed equipment, and the SN3500 will configure
itself accordingly.
The SN3500 shatters the price and size barriers of traditional EFIS
systems. With a full color display and a simple intuitive user
interface, the SN3500 brings high-end EFIS functions to the general
aviation cockpit.
