C H A P T E R 1 Welcome to the SN3308
CHAPTER 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.
CHAPTER 1 Welcome to the SN3308 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.
CHAPTER 1 Welcome to the SN3308 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.
C H A P T E R 2 Display Overview
CHAPTER Display Overview 2 Information Sources 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.
CHAPTER 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.
CHAPTER 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.
CHAPTER 2 AMBER Welcome to the SN3308 ■ ■ ■ ■ ■ YELLOW ■ ■ ■ Information associated with the cross-side NAV receiver (NAV2 if in pilot configuration, NAV1 if in co-pilot configuration) Information associated with the cross-side GPS bearing pointer (GPS2 when navigating on GPS1, GPS1 when navigating on GPS2) Restricted and warning areas ■ Active leg and waypoint of flight plan ADF bearing pointer BLUE ■ Outer marker indicator PURPLE ■ MOAs MAGENTA 2-4 Heading bug and associated data GPS
C H A P T E R 3 Operational Basics
CHAPTER 3 Operational Basics 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.
CHAPTER 3 Operational Basics The following messages may be displayed on power-up and indicate an abnormal situation. These messages will require one or more acknowledgments by pressing the [ACK] softkey. 3-2 CRC Self-Test FAILED ■ Program CRC is not the expected value. The “CRC Self Test Failed” message must not appear on powerup if flight operations are predicated on the use of the SN3308 Navigational Display.
CHAPTER 3 Operational Basics DEMO MODE: NOT FOR FLIGHT TO EXIT: POWER UP WHILE HOLDING NAV-MAP-BRG ■ The SN3308 has a special software mode for use 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.
CHAPTER 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.
CHAPTER 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.
CHAPTER 3 Operational Basics For a complete discussion of the SN3308 map features, see Chapter 5. Map Memory Location Factory Defaults 1 Flight plan waypoints and courselines only. 2 Flight plan waypoints and civil airports with runways>3500 ft. long. 3 Flight plan waypoints and high-level and low-level VORs. Note: both the scratchpad memory and the memory location 4 are empty by default and will not show up in the [MAP] button rotation until edited.
CHAPTER 3 Operational Basics Displaying Stormscope ® Data If a BF Goodrich WX-500 lightning detection sensor has been installed in the aircraft, it can be configured to display on the SN3308. To turn the lightning display on and off, and to control the various functions of the WX-500 sensor, press [SHFT]>[ ] to display the related softkeys. The available WX-500 functions are listed below. For more information, refer to the WX-500 User’s Guide.
CHAPTER 3 Operational Basics WX-500 SETUP MENU FUNCTIONS SELF TEST Causes the WX-500 to execute a self-test.The result is displayed in the WX-500 status word. NOTE: ten seconds or more may be required for the test to complete. DEMO Causes the WX-500 to send a series of simulated lightning strikes to the SN3308 display. ESC Exits the sub-menu mode. NOTE: Self-test or DEMO mode may be operated in-flight if desired with no adverse affect on SN3308 operation.
CHAPTER Operational Basics 3 Displaying the Deviation Bar The small course deviation bar (or “D-bar”) display in the lower portion of the screen is visible at all times. In addition, a larger conventional D-bar can be displayed.
CHAPTER 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.
CHAPTER 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.
C H A P T E R 4 Button Operations
Button Operations Map NAV PUSH: Selects the navigational instrument supplying information to the main course indicator, CDI, and upper display area. Each touch of the button cycles through the choices, which depend on installed equipment and selections made at the time of installation. A typical sequence is NAV1, GPS1, GPS2. The selected option is displayed on-screen next to [NAV]. In some installations, tuning an ILS frequency on NAV1 will override this setting and cause NAV1 to be selected.

C H A P T E R 5 Enhanced Moving Map Features
CHAPTER Enhanced Moving Map Features 5 Overview MAP operations allow you to display navigation information in the form of a “moving map” directly on the SN3308 display.
CHAPTER 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.
CHAPTER Enhanced Moving Map Features 5 Map memory currently displayed 250 KT RNG 75nm 307˚ BUR 307˚ 27.
CHAPTER 5 Enhanced Moving Map Features 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.

CHAPTER 5 Enhanced Moving Map Features Quick Map Off During normal operation press and hold the [MAP] key. After 1.5 seconds the map display will jump to MAP OFF from any memory. You can use this feature to quickly remove all map data from the screen at any time. Note that this feature will also turn off the WX500 Stormscope display, if enabled. Map Auto-Range The SN3308 provides a one-touch automatic ranging function. Pressing and holding the [ ] key for 1.
C H A P T E R 6 Getting the Most From Your SN3308
CHAPTER 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.
CHAPTER 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.
CHAPTER 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.
CHAPTER 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.
CHAPTER 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.
C H A P T E R 7 Flags, Abnormal Conditions and Messages
CHAPTER 7 Abnormal Conditions Flags and Abnormal Conditions The SN3308 detects abnormal conditions such as flagged navigation receivers and failed directional gyro or fluxgate. It also monitors its own internal temperature and provides warnings for overtemperature or loss of cooling conditions. Condition Display NAV flag HSI display: large red “X” through the CDI scale, and the deviation bar is not displayed. Numeric bearing display shows “- - -”. RMI display: bearing pointers are not shown.
