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.

C H A P T E R 1 Welcome to the SN3308
What is 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 pistonengine 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.

Operational and Legal Issues
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.

Conventions Used in This 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 aviationminded 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.”

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.
Appendix 2 of this manual contains fold-out pages with full-color illustrations of SN3308 displays. You may want to fold these pages out for reference while reading this manual.
Display Areas
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.
2 - 1
C H A P T E R 2 Display Overview
The lower display area presents the numeric data associated with the two bearing pointers. This includes the nav source, bearing and distance (if available). The upper section of this area also contains a display of the marker beacon lights and the GPS annunciators, if configured.
Indicators
Several different symbols, or indicators, are used in each of the display areas. These are described below: The white symbol is the
“lubber line,” pointing to the magnetic heading. It is always at the top of the display.
The amber symbol is the heading bug. This can be set by rotating the Heading Select knob or pressing [SYNC]. When the display has been set to 70-degree ARC mode using the [VUE] button, it is possible for the heading bug to be positioned off the screen. When this happens, the heading bug “parks” at the side of the screen nearest to its actual position, with the symbol displayed smaller than normal and close to the edge of the screen.
The symbol is the course pointer. By rotating the Course Select knob, you can set the course pointer to the desired course to a VOR nav source. When a long-range nav source is selected, the course pointer can automatically rotate to the desired track being sent by the nav source (i.e. “Auto-Slew”). The Course Deviation Indicator, or “CDI” (also known as a deviation bar or “D-bar”) is the movable center section of the course pointer which depicts deviation to the left or right of course. The CDI is also repeated at the bottom of the display. Note that the center CDI is not visible when the map display is enabled or if it is disabled in the [SHFT]>[NAV] function. When the display is in 70-degree ARC mode, it is possible for the head of the course pointer to be positioned off the screen. When this happens, the course pointer “parks” at the side of the screen nearest to its actual position, with the symbol displayed smaller than normal and close to the edge of the screen.
2 - 2
C H A P T E R 2 Display Overview
The single and double arrow symbols are the two bearing pointers. Depending on user-selected settings, these pointers may show the bearing to a VOR, ADF, or GPS waypoint. The numeric information from the instruments assigned to these pointers is displayed in the lower display area. The information is displayed in the same color as the bearing pointer with which it is associated. Also note that the tail of each pointer can be used to determine the bearing from the selected nav source.

You can configure and control the SN3308 to provide exactly the information you need at any point in the flight. Configuring the
SN3308 refers to connecting the appropriate data to a given display.
For example, a bearing pointer can be driven by either the VOR or the GPS receivers. Controlling the SN3308 refers to tailoring the display to suit your information needs. For example, you may decide to turn off a bearing pointer completely during the enroute portion of the flight and use it only during an approach.
Power-up Displays
On initial power-up, several different messages may be displayed on the SN3308. These messages are displayed along the top of the display. Some of the more urgent messages will require your acknowledgement by pressing the flashing [ACK] softkey. (VUE button)
The following messages are displayed on power-up under normal conditions, and do not require acknowledgment.

C H A P T E R 3 Operational Basics
DEMO MODE: NOT FOR FLIGHT
■
The SN3308 has a special
TO EXIT: POWER UP WHILE software mode for use
HOLDING NAV-MAP-BRG with the Sandel demonstrator chassis. This message should never appear on an instrument installed in an aircraft. When in DEMO mode, certain installation-specific items such as gyro settings, calibrations, etc. are erased.
If the message occurs, do not use the unit for flight until it has been reset by an avionics shop and a complete ground check has been performed.
In addition to these power-up messages, Chapter 7 describes a complete list of both normal and abnormal messages which can be displayed on the SN3308 at any time.
Selecting the Data
Sensor data is data that comes from various devices within the aircraft. This includes primary navigational instruments such as the
VOR, ADF and GPS or loran receivers, as well as instruments such as the directional gyro (DG), fluxgate compass and Stormscope
®
.
Heading data from the directional gyro and fluxgate compass is always applied directly to the SN3308’s compass card display, while other types of sensor data can be displayed in several different ways.
You can control these displays by configuring the course pointer, the bearing pointers, the map data and the weather data. See illustrations in Appendix 2.
3 - 3
C H A P T E R 3 Operational Basics
Selecting the Primary Nav Source
The SN3308’s course pointer and CDI (or “D-bar”) can be driven from VOR, GPS or loran data.
In some installations, the [NAV] button on the SN3308 is used to select the primary nav source. In others, an external switch performs this function and the [NAV] button has no effect. Refer to your
Aircraft Flight Manual Supplement for the details of your installation.
If external switching is used, this section does not apply.
If external switching is not used, then pressing the [NAV] button repeatedly will cycle through the available choices, which are specific to your aircraft and were configured by your installer. Selecting a primary navigation source also connects it to the autopilot, if configured.
Numeric data from the primary nav source, such as distance, bearing and groundspeed is displayed in the upper display area. If the selected nav source is a VOR receiver with a localizer frequency tuned, a status message of “LOC” appears at the upper left of the display as a reminder. If a valid glideslope signal is also being detected, the status message changes to “ILS”. The message is turned off if the VOR receiver is tuned to a normal VOR (omni-bearing) frequency.
In some installations, the ILS Lockout function may be enabled on the SN3308. This function forces the selection of the NAV receiver when an ILS frequency is selected. Refer to your Aircraft Flight
Manual Supplement to see whether ILS Lockout has been enabled for your installation.
NOTE: the following ONLY applies if ILS Lockout is enabled:
Tuning the number 1 VOR receiver (NAV1) to an ILS frequency will cause the SN3308 to override the nav source selection and will force
NAV1 as the selected nav source. The nav source will return to the previous selection after the ILS frequency is de-tuned.
While NAV1 is tuned to an ILS frequency and the nav source selection override is in effect, pressing the [NAV] button will not change sources. Instead, the following message is displayed: “NAV1 TUNED
TO LOC”. To defeat the override and restore the function of the
[NAV] button, simply select a non-ILS frequency in the NAV1 receiver.
3 - 4
C H A P T E R 3 Operational Basics
Selecting the Bearing Pointer 1 & 2 Nav Source
The SN3308 provides two independent bearing pointers which function in much the same way as a traditional radio magnetic indicator (RMI).
The head of each bearing pointer indicates the bearing to the nav source, and the tail of each pointer indicates the bearing from the nav source. Either pointer can be connected to any available navigation source: VOR, GPS/loran, or ADF. When GPS, loran or other long-range nav system is selected as the nav source, the bearing pointer indicates the bearing to the current active waypoint.
To select which nav sources are connected to either bearing pointer, press [SHFT]>[BRG]. The resulting menus provide choices for each pointer including nav source, OFF, and AUTO. AUTO will automatically select the same source as that selected for the primary course pointer.
The currently selected nav source is bracketed with asterisks (e.g.*AUTO*).
Displaying the Map Data
Map data consists of flight-plan waypoints from the LNAV receiver
(either GPS or loran), as well as nearby airports, navaids, intersections and airspace from the SN3308’s internal database. The map display is controlled by pressing the [MAP] button to cycle through the different map memory locations and by pressing the [ ] and [ ] buttons to zoom the map in and out. Pressing and holding the [MAP] button for
1.5 seconds will turn off both the map display and the WX-500
Stormscope display, if enabled.
A map memory is a list of which map items are to be displayed and which are not. There are four preset map memories, labeled 1 through
4. The factory default settings of the preset map memories are listed in the table below. There is also a scratchpad memory, labeled “S”, which you can change at any time. To save a particular configuration of scratchpad memory into one of the presets, press [SHFT]>[MAP] and then [COPY] to select the desired memory location.
To change the display items in the scratchpad memory, press
[SHFT]>[MAP]. Move the cursor up and down with the [MAP] and
[BRG] buttons, and enable or disable the desired items along the bottom row of the display. The contents of scratchpad memory will be retained until you make further changes, even after cycling the power.

Controlling the Display
The SN3308 is capable of displaying a tremendous amount of data at once. Using the SN3308 effectively means balancing desirable redundancy against undesirable clutter. This section describes the controls available to help you achieve that balance.
ARC View and 360-Degree View
As with sophisticated EFIS systems, the SN3308 allows you to switch between a traditional 360-degree view of the compass rose (see illustration 1 in Appendix 2) and a forward-looking ARC view (see illustration 2 in Appendix 2). The ARC view places the airplane symbol at the bottom of the screen and the heading indicator along an ARC of approximately 70-degrees around the top of the screen. Arc view maximizes the display of the ground track ahead of the aircraft and provides the greatest amount of screen area for map data.
Press [VUE] to switch back and forth between ARC and 360-degree views. This action only affects the screen display – all navigation sources, bearing pointers, and other settings remain the same.

Stormscope display is turned on, “MAP OFF” will not appear even though the map is deselected. To turn off both the map and the
Stormscope display simultaneously, press and hold the [MAP] button for at least 1.5 seconds.
Displaying the Course Pointer
The course pointer itself can be removed from the display to allow navigating on the courseline from your LNAV receiver. Press
[SHFT]>[NAV], then the [CRS PTR] softkey to toggle the setting between “AUTO” and “ON”.
When set to “ON”, the course pointer is always displayed.
When set to “AUTO”, the course pointer will be turned off under the following conditions:
■
■
■
An LNAV receiver (GPS or loran) is selected for navigation, and
A waypoint or flight plan is entered, and
Flight plan waypoints are enabled on the current map memory.
When NAV is selected for navigation, the course pointer is always displayed.

C H A P T E R 3 Operational Basics
Auto-Slewing the Course Pointer
One unique feature of the SN3308 is its ability to automatically rotate the course pointer to the desired course being sent digitally from a
GPS or loran. This feature is called “auto-slewing,” and is especially useful during a GPS approach or while flying a complex flight plan.
To enable auto-slewing, press [SHFT]>[NAV], then press the softkey labeled “AUTO SLEW” to toggle this feature on and off. With autoslew set “ON”, the course pointer will be set to the desired track being sent by the selected GPS or loran. Turning the course select
(OBS) knob has no effect, other than displaying the message
“LEG/AUTO (AUTO SLEW) IS ON”. With auto-slew set “OFF”, the course select knob rotates the course indicator in the same way as a conventional HSI.
Note that certain GPS receivers such as the King KLN-90B and Garmin
GNS 430 support an ‘OBS’ or ‘HOLD’ mode which when active will override auto-slew.
Centering the Heading Bug or Needle
To rapidly set the heading bug to the aircraft’s present heading, press [SYNC]. To rapidly set the course pointer to the current
Direct-to course (i.e., to center the CDI), press [SHFT]>[SYNC].
When no valid course is available, such as when flying a LOC/ILS approach, [SHFT]>[SYNC] rotates the course pointer to the lubber line (current heading) instead.
Setting the Map Range
Whenever map data is being displayed, the [ ] and [ ] buttons are available to zoom the image in and out. Each press of either button selects the next higher or lower map range. The map range refers to the depicted distance, in nautical miles, from the airplane symbol to the outside of the compass tick marks. The current map range is displayed at the upper right portion of the screen and is selectable between 1 and 1000 nautical miles.
3 - 1 0
C H A P T E R 3 Operational Basics
When either a direct-to waypoint or a full flight plan has been entered on the LNAV, a one-touch auto-ranging function is available on the
SN3308. Pressing and holding the [ ] button for at least 1.5
seconds will cause the map range to increase smoothly until reaching a setting at which the entire flight plan is visible. Similarly, pressing and holding the [ ] button for at least 1.5 seconds will set the map range to a value at which only the current waypoint is visible.
A-B Function
A unique feature of the SN3308 is its ability to maintain two different groups of display settings and to quickly swap back and forth between them. This allows you to set up a particular screen display and memorize the settings for later use. For example, your preferred
“enroute” setup might be ARC view with only bearing pointer 1 displayed, connected to a VOR navaid. Your “approach” setup might be in 360-degree view with bearing pointer 2 displayed, connected to an ADF (to monitor the locator outer marker). In this case, you would simply set up either display, press [A-B], and then set up the other display. Pressing [A-B] repeatedly will then switch between the two displays. The current display setting in use is indicated by the letter “A” or “B” at the top of the screen.
Press [SHFT]>[A-B] to make both displays identical. Whichever display is visible at the time [SHFT]>[A-B] is pressed will be copied into the non-visible display. At this point, pressing [A-B] will have no apparent effect (other than changing the “A” or “B” legend) since both displays have the same content.

PUSH: The SN3308 can display either of two presentations of information, referred to as A and B. [A-B] cycles the display between these two presentation memories, each of which retains the selected values for:
■ Map range
■ Map selection
■ Bearing pointers ON or OFF
■ [VUE] selection
The only user settings not retained are the primary nav source selection and the actual course pointer and heading bug settings. No user action is required to store changes to A or B. Any change to the above parameters that is made while A is active become part of A. Any changes made while B is active become part of B.
Pushing [A-B] swaps the active screen for the inactive screen. Either A or B is displayed at the top of the display indicating which memory is currently active.
This two-view option can be used in a wide variety of ways. It can do something as simple as flip-flopping between screens that differ only in the map range depicted; or it can be used to switch from a simple HSI view to a full EFIS-like display.
HOLD: No action performed.

Overview
MAP operations allow you to display navigation information in the form of a “moving map” directly on the SN3308 display. You have extensive control over what kinds of navigation information are displayed on the map:
■
■
■
■
■
■
Airports/Runways
Controlled and Special Use Airspace
VORs
NDBs
Intersections
GPS Flight Plans (with or without course line)
Within each of these classes of map objects you may fine tune exactly which items you want displayed. For example, you may choose to exclude military or private airports, or those with unpaved runways or runways shorter than a particular length. Similarly, you may elect not to display terminal VORs or low-powered NDBs, or to display
Class B airspace and Restricted Areas but exclude Class C airspace and
MOAs. As you’ll see, the SN3308 offers great flexibility in how you configure your moving map display.
Finally, you may store up to four different map configurations, and then quickly switch from one to another as appropriate to your phase of flight. For instance, when cruising at FL180 or higher, you might want to display only high-altitude VORs (but not Terminal or Lowaltitude VORs), Special Use Airspace (but not Class B or Class C), and only airports with paved runways of 6,000 feet or longer. The
SN3308 allows you to save such a map configuration in one of its four map memories and then recall it as needed.
All the airports, navaids and intersections on the moving map, except for GPS flight plan fixes, come from the internal database of the
SN3308 and are color-coded amber. GPS flight plan fixes come from the GPS receiver and are color-coded magenta/white. Controlled and
Special Use Airspace also comes from the internal database, and are color-coded according to its type (Class C and Class B in green, MOAs in purple, Restricted and Warning Areas in yellow, and Prohibited
Areas in red).

C H A P T E R 5 Enhanced Moving Map Features
Note: The SN3308 requires a connection to a GPS receiver in order to display the moving map. The map display, including the flight plan from the GPS1 receiver, will also be shown when NAV1 or NAV2 is selected as the primary
Nav source.
Internal Database
Non-flight plan data including airspace is referred to as the “internal database” and is stored in the SN3308’s internal memory. The internal database can be periodically updated from a Windows-based
PC or laptop. The expiration date of the internal database is shown during the power on sequence. As this database is for supplemental use only and not intended for primary navigation, it is not required to be kept up to date. Database updates are available directly from
Sandel Avionics, and may be purchased online at www.sandel.com.
Newly manufactured units may not contain an internal database when shipped from the factory. Your avionics installer should obtain and install the most recent database prior to completion of a new installation. The SN3308 will operate normally without an internal database except that only GPS flight plan waypoint information will then be displayed.
Map Controls and Displays
Information associated with control of the map is displayed as follows:

Map Memories
The [MAP] pushbutton cycles from MAP OFF through a maximum of four possible map memory locations, or memories, plus a scratchpad memory. The map memory you are currently displaying is shown at the top of the map status bar and will show S, 1, 2, 3 or 4.
Any memory which is empty is skipped during the MAP rotation sequence. In the default setup of the SN3308, memories 1, 2 and 3 contain factory settings, and memories S and 4 are empty.
Map memory S has been designated the scratchpad memory and the remaining memories 1-4 are designated as preset memories. All onscreen changes are made to S but can be copied to memories 1-4 as desired. The purpose of having a separate scratchpad is to allow you to quickly add or delete items from your map display to attend to a current flight situation, without changing presets you may already have made.
The map setup function, described on page 5-7, shows how to make changes to the map memories. The following table lists the 24 items that can be independently configured for each map memory:
There are a large number of selection items. However, the organization of the SN3308 is intended to make the map setup process as easy as possible. You should experiment often with the map settings until you develop the style of operation best suited to your flying.

Prohibited airspace is shown in Red and cannot be turned off on the map display.
Flight plan waypoints can be selected to show as facility icons (such as
VOR or INT icons) or to show as waypoint icons only using map setup page 8. Most RS-232 GPS receivers are limited to showing waypoint icons only.
Runways below a selectable minimum length may be masked from the display by pressing the MIN LEN softkey. This parameter may be set to 2000', 2500', 3000', 3500', 4500', 5500', 6500' or ALL.
TACAN is a single setting which will affect all of the map memories.
This can be set from within any map memory and will affect all map displays.
Getting Started – Example
The Factory Default SN3308 map memories are set up as follows:
S: Empty
1: Flight plan only with courselines
2: Flight plan and paved civil airports over 3500' in length
3: Flight plan and HI and LO VORs
4: Empty
To get started, we recommend you try some operations on the ground. Ensure that your GPS receiver is operating, and enter a flight plan using its normal procedures. You can use the simulator mode of your GPS receiver if it has one, or if it does not, make sure the flight plan you enter is near the airport where you are located.
Press [MAP] until “1” shows at the top of the map status bar. With this setting, you should see the waypoint icon next to the [MAP] key, indicating that flight plan waypoints are enabled on the display.
Use the [ ] or [ ] key to adjust the display range, which is the number of miles between the symbolic airplane and the outer compass ring.
You should see your GPS flight plan on the display. The active leg and waypoint will be shown in magenta and the other waypoints and courselines will be shown in white.
5 - 6
C H A P T E R 5 Enhanced Moving Map Features
Set the map range to 30 nm, and press [MAP] so that “2” is displayed.
The display should show your flight plan as above, overlaid with local airports with runways over 3500'. Note that the airport icon shows on the map status bar indicating airports are being displayed, and that on-screen airports are shown in amber. The amber color indicates that the source of the airport data is coming from the internal database. The flight plan information, coming from the GPS receiver, is displayed in magenta and white.
Lower the map range to 10nm, and notice that as the display zooms in any airport shown will change from the airport icon into a runway
(or multiple runways). Below 7nm the runway numbers will also be added so that as you zoom in you can plainly see the airport identifier, runways, and runway numbers. During flight, the display will rotate and update with the aircraft in real-time.
Press [MAP] to change to memory 3. Notice that airports will be removed and instead local LO and HI VORs will be shown in Amber.
Note that on the map status bar the airport icon will be removed and the VOR icon will display, indicating that VORs are enabled.
Pressing [MAP] again will skip memory 4, because it is empty, and jump directly to MAP OFF. All the map information will be removed from the screen. Further presses of the [MAP] key will again cycle through map memories 1, 2 and 3 and then back to MAP OFF.
Map Setup
We are about to change what is displayed on the map, using memory
1 as the baseline. Start by pressing [MAP] until “1” shows at the top of the map status bar.
Press [SHFT]>[MAP] to enter Map Setup. All settings in memory 1 are copied to S (the scratchpad memory), and you can now make non-permanent changes with the softkeys. Notice that you are editing memory S. If you want to save these changes back into memory 1, you can use the COPY function, described on page 5-9.

C H A P T E R 5 Enhanced Moving Map Features the map display. Assuming you are in a location with nearby Class B or C airspace, you should see the airspace boundaries on your display.
Notice that you are displaying scratchpad memory S, and you have added airspace depiction.
Note: During map setup operations the SN3308 continues to operate normally. The compass and deviation displays are still active, and the HDG and CRS knobs still operate.
Escaping Map Setup
Note the flashing ESC softkey. Pressing this softkey will immediately exit the map setup page, and the map display will remain as you programmed it. You should see both your flight plan and airspace on the map display.
Setting Other Items
Using [SHFT]>[MAP] again, try changing other items on different map setup pages and observe their effects. Note that you are not changing memories 1-4 by these actions. In fact, if during normal operation you are displaying any memory 1-4, you can press
[SHFT]>[MAP] to create a new baseline for the scratchpad memory.
Copying Settings into Preset Memories 1-4
Map settings can be retained for future use by storing them into one of the four memory presets. This is done by copying the scratchpad memory into one of the presets using the COPY function.

Automatic Decluttering
It is possible for the SN3308 map display to become too cluttered to read, such as by turning on all possible map items. This also has the undesirable side effect of slowing down the display update rate.
The SN3308 will automatically remove items from the display if the total number of items is too great to display. When this occurs, it is indicated by a color change in the associated icon in the map status bar. Normally these icons are amber, but any item which is not showing all possible occurrences because of an automatic decluttering will change the icon color to yellow.
Normally the SN3308 will allow up to approximately 50 icons before this action occurs, but this number may be smaller if complex airspace is simultaneously being displayed. When auto-decluttering occurs, it occurs first to the objects closest to the aircraft. When the display is zoomed-in, these objects will reappear and the associated status bar icon will turn back to amber.
Maximum Range of Internal Map Data
During normal operation, the SN3308 only displays items from its internal database which are within 150 nm of the current aircraft position (300nm for VORs), even when the selected range is larger.

The SN3308 provides a one-touch automatic ranging function.
Pressing and holding the [ ] key for 1.5 seconds will cause the
SN3308 to zoom to the lowest map range at which the current waypoint is still visible. Conversely, pressing and holding the [ ] key will zoom to the highest setting needed to display the full flight plan.

C H A P T E R 6 Getting the Most From Your SN3308
If you have never flown with an HSI, you’ll find that the combination of heading information and selected nav course is a powerful tool. If you have never flown with an RMI, you’ll find that a simple bearing pointer can greatly improve your situational awareness. And if you have never flown with an SN3308, with its combination of HSI, RMI and moving map in a single display, you’re about to discover how the whole can be greater than the sum of its parts. Please refer to the color fold-out pages of this manual while reviewing the following.
Using the HSI
A horizontal situation indicator (HSI) is basically a VOR needle superimposed over a directional gyro (DG) ring, or heading indicator.
On a conventional VOR display, a course deviation indicator (CDI) indicates left or right deviation, and an Omni-Bearing Select (OBS) knob allows selection of the desired course. On an HSI, the OBS knob turns a course pointer which rotates until it is pointing to the desired course on the DG ring. The center section of the course pointer swings left and right to perform the CDI function. A glideslope
(vertical deviation) scale is displayed on the right side of the course pointer, and the TO/FROM flag is a white triangle displayed next to the course pointer, either above or below the CDI.
By using the heading indicator as a background for the entire course pointer/CDI combination, an HSI gives you an immediate visual indication of the location of the desired radial. You can see at a glance your intercept angle to the desired radial, whether or not you have flown through the radial, and whether you are tracking inbound or outbound.
In normal operations, you should connect the HSI course pointer to your primary navigation source. Do this by pressing the [NAV] button until the desired source is annunciated.
When the nav source is a VOR receiver, turn the OBS knob until the course pointer is set to the desired radial. To immediately center the needle and proceed DIRECTLY TO the VOR station, press
[SHFT]>[SYNC]. If the receiver is tuned to a localizer frequency, set the course pointer to the published inbound course. Even though the
OBS setting doesn’t affect the CDI when a localizer is tuned, it is very
6 - 1
C H A P T E R 6 Getting the Most From Your SN3308 important to maintain the correct visual orientation on the HSI.
In addition, the autopilot will be using the OBS to obtain a course reference. Pressing [SHFT]>[SYNC] when a localizer frequency is tuned rotates the course pointer to align with the present heading.
When the nav source is a long-range nav receiver such as GPS or loran, the SN3308’s course pointer can auto-slew, or automatically point to the correct course. The auto-slew function can be enabled or disabled by pressing [SHFT]>[NAV] and toggling the AUTO SLEW softkey. If enabled, when the nav receiver sequences to subsequent waypoints on a flight plan or an approach, the course pointer will auto-slew to each course in turn. Simply use standard intercept and tracking techniques to keep the needle centered.
Bearing Pointers (RMI)
Conceptually, a Radio Magnetic Indicator (RMI) is even simpler than an HSI. A traditional RMI provides one or two independent pointers which point to the navigation station, much like an ADF display. But instead of using a fixed compass card like many ADF displays, an RMI automatically rotates the compass card so that the current heading is always at the top of the display. Thus, each pointer indicates the actual bearing TO the station (reading the head of the pointer) or FROM the station (reading the tail of the pointer).
The two bearing pointers on the SN3308 are especially useful because they can be connected to a VOR receiver, an ADF receiver, or a GPS/loran receiver. Since all three types of navigation signals are converted to a common display format in this case, the SN3308’s bearing pointers make excellent crosschecks against your primary nav source.
To make the best use of the Bearing Pointers we recommend that you select “AUTO” as the source for bearing pointer 1, and that it be displayed at all times.
6 - 2
C H A P T E R 6 Getting the Most From Your SN3308
The bearing pointers are useful in the following situations:
Cross-check Bearing pointer uses a different nav source to track the same waypoint as the HSI. Bearing pointer aligns with course pointer if both receivers agree.
Expanding CDI scale Bearing pointer is set to the same nav source as
HSI. If CDI needle is pegged, the bearing pointer will give a visual indication of how soon until intercept. Especially useful when intercepting a localizer or close-in to a VOR station when the CDI is most sensitive.
Crossing radial
ADF tracking
Bearing pointer is connected to a VOR or NDB abeam the desired track. Use to cross-check DME fixes and identify step-down fixes or changeover points.
Bearing pointer is connected to the ADF and used for primary navigation. The HSI course pointer cannot be connected to an ADF.
Example: Flying an ILS
In this example, we’ll fly a full ILS approach with a standard configuration. We’ll see how the SN3308 can be set up to provide course guidance both outbound and inbound, as well as crosschecking of navigation data. The fictional approach is depicted below:
Assume that we are approaching the airport from the northwest, heading 140 degrees. We are told to proceed direct to the locator outer marker (LOM), and are cleared for the ILS to runway 36. The procedure is to navigate to the marker using the ADF, track outbound on the localizer, perform a procedure turn, and then reintercept the localizer inbound.
To configure the SN3308 for the approach, we will select the following nav sources: NAV1 for the HSI course pointer, ADF for bearing pointer #1, and GPS for bearing pointer #2. The NAV 1 receiver should then be tuned to the localizer, the ADF should be
6 - 3
C H A P T E R 6 Welcome to the SN3308 tuned to the locator outer marker, and the GPS should be given the airport as the “direct-to” destination. Rotate the OBS knob until the head of the course pointer is aligned with the inbound course of 360˚.
In this configuration, the HSI course pointer will track the localizer, bearing pointer #1 will point to the outer marker, and bearing pointer #2 will point to the airport just as a general reference and final cross-check.
To begin the approach, keep bearing pointer #1 at the top of the display. Assuming zero wind, this will track you directly to the LOM
(in the presence of a crosswind, use standard ADF tracking techniques). As you near the localizer course, the CDI needle will start to swing inward. Because you are flying the localizer outbound, the tail of the course pointer is near the top of the display and the left-right sense of the needle is correct. As the needle centers, the
OM light will start flashing and a few seconds later, the #1 bearing pointer should swing around to the bottom of the display. These are all confirmations that you have passed the outer marker and are established on the localizer outbound.
As you keep the CDI centered on the outbound leg, both bearing pointers should line up with the head of the course pointer at the bottom of the display. You are now using VHF nav, ADF and GPS simultaneously to verify the proper outbound course. In addition the
LOC-DME distance from the threshold (if available) is displayed in the upper left corner, and this can be cross-checked by the GPS distance from the airport in the lower left corner.
Perform the procedure turn by simply turning to a heading that puts the course pointer at the desired angle, usually 45˚. After holding this heading for the desired time or distance and then turning a full 180˚, the aircraft will be inbound on a 45˚ intercept to the localizer. Now the course pointer and both bearing pointers will be in the upper half of the display. If the CDI needle is pegged to the left, bearing pointer
#1 will give a visual indication of how soon to expect an intercept.
Again, as the CDI begins to move inward, bearing pointer #1 will be approaching the head of the course pointer.
6 - 4
C H A P T E R 6 Welcome to the SN3308
Tracking the localizer inbound, keep the CDI centered using standard techniques. Outer marker passage will be marked by the flashing OM display and bearing pointer #1 will swing to the bottom of the display. LOC-DME and GPS distance can be used as a cross-check.
If the procedure terminates in a missed approach, especially one in which ATC issues multiple vectors, bearing pointer #2 becomes especially useful. It simply points at the airport, which can greatly improve your situational awareness.

Messages
The Sandel SN3308 displays different messages to alert the pilot.
The messages are initiated by the Pilot, the Built In Self Test (BIST), the Power On Self Test (POST) or by the System. Most of the Pilot initiated messages are shown on-screen for two seconds and are removed automatically. Error messages which are considered critical are places on-screen permanently until acknowledged. The
Acknowledgment is done using the ACK soft-key which will appear and flash when such a message appears. It also monitors its own internal temperature and provides warnings for over-temperature or loss of cooling conditions.

BIST is Built In Self Test. This runs continuously while the SN3308 is operating.
The internal temperature is continuously monitored. An overtemp condition will only occur if the cooling fan failure occurs first (the fan stops turning) or the cooling fan filter is clogged or obstructed. As the temperature rises a warning will be issued approximately 10 minutes prior to shutdown as a warning. If shutdown occurs the
SN3308 will shut off the projection lamp and continue operating, and resume normal operation as the internal temperature falls.
The Inverter failure messages will only appear if a master inverter is installed.
Gyro Failures will only be annunciated if the installed Gyro has a valid flag output. If the
"Fluxgate Failed" message appears check the
Gyro circuit breaker which is usually the source of Fluxgate power.
All other functions of the SN3308 continue to operate normally when the map has failed.

A P P E N D I X 1 Technology of the SN3308
The Sandel Avionics SN3308 is the first member of an entire family of products to be based on a new, state-of-the-art display technology.
This new type of display, along with a reduced instruction-set (RISC) microprocessor and highly integrated peripheral chips, makes it possible to acquire and display data from many different cockpit instruments.
Traditional electronic cockpit displays have been based on either cathode-ray tube (CRT) or direct-view liquid-crystal display (LCD) technology. One disadvantage of both CRTs and LCDs is that neither can display an image out to the very edge of the screen. This becomes especially significant when the outside dimension is constrained to only three inches across! In a 3 inch cockpit instrument, the amount of unusable display area on a traditional CRT or LCD can approach 50%.
The SN3308 solves this problem by using a much smaller LCD as the heart of an image projection system. The light beam from a ruggedized halogen bulb is first passed through a series of color splitters, with each color beam aimed at the corresponding set of pixels in the LCD. The resulting high-intensity color image is then projected through a magnifying lens onto a high-contrast optical screen. The final result is a crisp, clear color image which spans the full height and width of the instrument.
Internally, the physical design of the SN3308 is as unique as the display. Circuit boards are mounted lengthwise, close to the metal case, to keep clear of the light path between the projection lens and the screen. The nine pushbuttons are actually at the ends of long connecting rods which curve back to their switches so as not to cast a shadow on the screen. Even the two knobs actually turn long segmented shafts connected by universal joints, which provide a precise mechanical connection while remaining clear of the light path.
The display flexibility of the SN3308 is made possible by the highspeed digital conversion of all analog signals coming into the unit.
Heading gyro input, ADF bearing, and even composite VOR signals are received, conditioned, and immediately converted into a common digital format. This allows completely different types of navigation signals, such as VOR, ADF, and GPS, to be displayed simultaneously.
