Revision notice
The “Effectivity, Errata, and Revision History” allow the use of this Pilot
Guide with a specific software release. The “Effectivity, Errata, and
Revision History” specifically lists the software to which this Pilot’s Guide
applies and corrects any errors or omissions in this revision of the Pilot’s
Guide. Document number 82009-PG-ERR, Effectivity, Errata, and

Operational and legal issues
The information displayed on the SN4500 is generated by external
equipment. It is the pilot’s responsibility to ensure the correct
configuration and use of the external equipment. The SN4500 is subject to
all legal and operational limitations of the equipment supplying data to it.
Always refer to your approved Aircraft Flight Manual Supplement for
operation and limitations on the use of installed equipment.
Note: Because aircraft vary in their installed equipment, it is important to
note that what is displayed on the SN4500 may vary depending on the
presence or absence of equipment.
Please keep in mind that it is required by Federal Aviation Regulations to
have on board current charts appropriate to the flight. The moving map on
the SN4500 does not fulfill this requirement. A current internal database is
not required but is recommended. The internal database supplies
supplemental data only (such as nearest airports, navaids and airspace).
Flight plan waypoints and IFR approaches are supplied to the SN4500 by
the associated IFR approved GPS receiver. Supplemental data is intended
for positional awareness only and should not be used for primary
navigation.

WELCOME TO THE SN4500
82009-PG, REV F SANDEL SN4500 PILOT’S GUIDE PAGE 1-1
CHAPTER 1 WELCOME TO THE SN4500
What is the SN4500
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 SN4500 Primary Navigation Display is an enhanced Electronic
Horizontal Situation Indicator (EHSI) which packs the essential features of
an EFIS NAV display plus enhanced features into a standard four-inch
instrument. By combining the functions of an electromechanical HSI, an
RMI, a moving map, data link weather, TCAS and a Stormscope® display
into one instrument, the SN4500 ties together the critical elements of
situational awareness.
The SN4500 uses Sandel’s proprietary LED backlit rear-projection display
technology for brilliant image quality and long operating lifetime.
Internally, the SN4500 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 SN4500 will configure itself accordingly. In
addition, an internal recorder can be enabled that will record up to the last
10 hours of flight data. This data can be used by Sandel to assist in
troubleshooting.

Figure 2-1 SN4500 Physical Features
The following section of the manual describes the appearance of the
SN4500 display and identifies each functional element. Detailed
descriptions of these elements and a tutorial guide to their use are
presented in later sections as noted in Figure 2-1 above.
Display Areas
The primary display area shows either a 360-degree FULL view or a 70-
degree ARC view, as indicated by the white compass ring. The cyan
airplane or triangle represents the aircraft’s current position. The primary
display area may also depict the current GPS flight plan, airports, navaids,
intersections, airspace, traffic, FIS-B datalink weather and/or Stormscope®
data if the map feature has been enabled. Several indicators (see below)
are also presented within the primary display area.

DISPLAY OVERVIEW
82009-PG, REV F SANDEL SN4500 PILOT’S GUIDE PAGE 2-2
Figure 2-2 Display Areas
The upper display area presents data from the selected course navigation
instrument. The data displayed depends upon the navigation source
(VOR/DME or GPS) but it will generally include bearing, distance, and
ground speed, if available. The upper display area also includes
information on the map status, WX-500 Stormscope® status (if installed),
and an annunciation on whether the VOR NAV display is currently
receiving either a localizer or a full ILS (localizer/glide slope) signal.
The lower display area presents the numeric data associate with the two
bearing pointers. This includes the NAV source, bearing and distance (if
available). The right section of this area contains a display of the marker
beacon lights if configured and heading data during LNAV operations. The
left section includes GPS annunciators, if configured.
Indicators
Several different symbols, or indicators, are used in each of the display
areas. These are described below:
Lubber line [white]: Points to the magnetic heading. It is always
at the top of the display.
Heading bug [orange or white]: This can be set to a desired
heading by rotating the Heading Select knob (right knob).
