Errata
1. Northstar GPS/Loran: As of this date the Northstar
GPS or Loran will only draw a courseline on the
SN3308 when a flight plan is activated. A courseline
will not be drawn when using a direct-to.
Also, please note that there may be as much as a 30
second delay in auto-slewing on the SN3308 when
sequencing waypoints in a Northstar flight plan.
2. BFG WX-500 Stormscope®: The following
information is in addition to that presented in Chapter 3
of the Pilot’s Guide:
a) The indicated strike rate applies only to the visible
area of the display. Zooming in the map range may
cause the indicated strike rate to decrease, since
active weather areas may no longer be visible.
b) No lightning strikes will be displayed when the
current map range is less than 20 nm.
The above items are standard operating features of the
WX-500.
c) Error messages from the WX-500 are indicated on
the SN3308 are indicated by a message ‘Exx’ where
‘xx’ is a two digit code. Refer to your WX-500
User’s Guide for interpretation.

d) A fatal fault on the WX-500 is indicated by a
message ‘FLT’. Please see your authorized
Stormscope dealer for service.
3. Back Course Approach Operation:
When flying a back course approach, the course pointer
should be set to the published front course. In software
versions 2.10 and later, the bottom CDI will
automatically reverse sense when the course pointer is
more than +/-90 Deg from the lubber line. The label
‘BC’ will appear above the bottom CDI during a back
course approach as a reminder to the pilot as shown in
the diagram below.
4. Appendix 2: Selected Course and Current Waypoint,
Bearing & Distance callouts are reversed on page A2-4.

5. Page 7-1: For condition of Loss of Gyro and fluxgate,
Display Column should read “Compass rose color
changes from white to amber.” Applies to version 2.11
software and later.

Whatis it?
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 positional
awareness.
Unfortunately, EFIS is rarely found in smaller General Aviation (GA)
cockpits. The cost, complexity, and sheer physical size of most EFIS
systems usually relegate them to jets, turboprops, and large piston-
engine twins. EFIS screens of 5" x 7" are not uncommon, and the
system cost can equal or exceed the entire value of a recent-vintage
Bonanza, for example.
The Sandel Avionics SN3308 packs the essential features of an EFIS
nav display into a standard three-inch instrument, at a fraction of the
cost of a full EFIS. By combining the functions of an HSI, an RMI, a
moving map and a Stormscope®display into one instrument, the
SN3308 ties together the critical elements of situational awareness.
And by adding to that a 3-light marker beacon and GPS annunciator
displays, the SN3308 becomes the virtual equivalent of an EFIS nav
display, sized and priced for GA cockpits.
Sandel’s unique electro-optical technology eliminates the unusable area
surrounding the display in most CRT and LCD displays. With a usable
image spanning the entire instrument, the 3-inch SN3308 actually
provides more viewing area than most 4-inch CRT displays.
Internally, the SN3308 uses high-speed digital converters to allow it
to receive signals from virtually every type of navigation receiver ever
installed in a GA aircraft. A comprehensive set of maintenance pages
allows the installer to simply specify the make and model of the
installed equipment, and the SN3308 will configure itself accordingly.
The SN3308 shatters the price and size barriers of traditional EFIS
systems. With a full-color display and simple, intuitive user interface,
the SN3308 brings high-end EFIS functions to the GA cockpit.

CHAPTER

Operationaland LegalIssues
Because aircraft vary in their installed equipment, it is important to
note that what is displayed on the SN3308 will vary depending on
the presence or absence of equipment such as GPS, Stormscope®,
DME, etc. At a minimum, the aircraft equipment should include a
heading system (remote directional gyro and fluxgate compass), a
VHF (VOR/LOC) nav receiver and a long-range navigation receiver
such as GPS or loran.
Please keep in mind that you are required by Federal Aviation
Regulations to have on board current charts appropriate to the
flight you are undertaking. The moving map on the SN3308 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 and navaids). IFR
flight plan waypoints and courselines are supplied to the SN3308 by
the associated IFR GPS receiver through the receiver’s serial data
link. Supplemental data is intended for positional awareness only
and should not be used for primary navigation. Check your Aircraft
Flight Manual Supplement for any additional specific operational
requirements of your installation.
Also keep in mind that the SN3308 is only a display device; it does
not determine the aircraft’s heading or sense the aircraft’s position.
All information displayed on the SN3308 is generated by external
radios and instruments. It is the pilot’s responsibility to correctly
configure and utilize these external devices. The SN3308 is subject
to all legal and operational limitations of the devices supplying it
data. For example, if your GPS receiver is limited to VFR use only,
you cannot configure the SN3308 to display only GPS data during
an IFR flight. Always refer to your Aircraft Flight Manual
Supplement for any limitations on the use of installed equipment.

CHAPTER

ConventionsUsed inThis Manual
The name of a button is always placed within square brackets when
the button is described in text. For example, “...push [SYNC] to
align the heading bug...”
In some cases, the text will describe a two-button sequence, for
example, “...push [SHFT]>[SYNC] to center the needle...”. This
means that the buttons are to be pushed consecutively, not held
simultaneously.
This manual will use terms which should be familiar to aviation-
minded readers, such as “selected radial” and “magnetic heading.”
Terms which are specific to the SN3308 will be placed in italics, for
example, “ lower display area .”

InformationSources
The SN3308 will display data from some or all of the following
instruments:
■NAV1 and NAV2 receivers
■DME1 and DME2
■LNAV1 and LNAV2 (GPS or loran)
■Marker beacon receiver
■Weather detection (WX-500 Stormscope®)
■ADF1 and ADF2
■Directional gyro and fluxgate
The following section of the manual describes the appearance of the
SN3308 display, and identifies each functional element. Detailed
descriptions of these elements and a tutorial guide to their use are
presented in later sections.

DisplayAreas
The primary display area shows either a 360-degree or a 70-degree
ARC view, as indicated by the white compass ring. The white airplane
represents the aircraft’s current position. The primary display area
may also depict the current GPS flight plan, airport, navaids,
intersections, airspace and/or Stormscope®data if the map feature
has been enabled. Several indicators (see below) are also presented
within the primary display area.
The upper display area presents data from the selected course
navigation instrument. The actual data displayed depends on the
navigation source (VOR/DME, GPS, or loran) 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 of whether the
VOR nav display is currently receiving either a localizer or a full ILS
(localizer/glideslope) signal.
