1. INTRODUCTION Thank you for purchasing the Dynon Avionics EFIS-D100. This section provides some important cautionary information and general usage instructions for this manual. Before You Fly We strongly recommended that you read this entire guide before attempting to use the EFIS-D100 in an actual flying situation. Additionally, we encourage you to spend time on the ground familiarizing yourself with the operation of the product.
Introduction Warning Dynon Avionics’ products incorporate a variety of precise, calibrated electronics. Except for replacing the optional internal backup battery in EFIS-based products per the installation guide, our products do not contain any field/userserviceable parts. Units that have been found to have been taken apart may not be eligible for repair under warranty.
Introduction The following icons are used in this guide: Any text following this icon describes functionality available only with the HS34 HSI Expansion Module connected to your system. Any text following this icon describes functionality available only with the AP74 Autopilot Interface Module connected to your system. Any text following this icon describes functionality that is possible when multiple Dynon Avionics products are networked together via the Dynon Smart Avionics Bus (DSAB).
2. PRODUCT OVERVIEW This section provides a general overview of the various parts of the EFIS-D100 as well as a theory of operation. The information in this section serves as a reference only and helps familiarize you with the inner workings of the unit. It should not be used for diagnostic or reparative work. EFIS-D100 Hardware The EFIS-D100 uses solid-state sensors to provide accurate and reliable information about your flying environment in an easy-to-use interface.
Product Overview SENSORS AND INPUTS Attitude information is obtained from 3 solid-state gyrometers, 3 solid-state accelerometers, and the airspeed pressure sensor. Heading information is obtained from 3 solid-state magnetometers housed in the EDC-D10A. Airspeed, altitude and angle of attack are obtained from three separate pressure transducers. HSI information can be displayed when connected to Dynon’s HS34, a Garmin SL30, or a compatible GPS unit.
Product Overview DISPLAY The display is a 7-inch, 854 by 480 pixel, 400 nit or 800 nit LCD screen, depending on the model. BUTTONS AND KNOBS User interaction takes place via the six buttons along the bottom of the front panel of the unit. When an AP74 Autopilot Interface Module is configured to control the EFIS-D100, its VALUE knob changes values when in various EFIS menus. When no menus are displayed the AP74 can adjust the barometer, altitude bug, and heading bug.

Your EFIS attitude is not reliant on any single external system.
Product Overview this sequence of event occurs, the EFIS-D100’s attitude accuracy is reduced; use other references in the aircraft to crosscheck against the EFIS-D100’s attitude. COMPASS ACCURACY AND AUTOPILOT PERFORMANCE If you are using your EFIS-D100 to control Dynon’s Autopilot, it is critical that the magnetic heading be as accurate as possible for comfortable operation in HDG mode and radio-based VOR/NAV mode.
3. PRODUCT OPERATION After reading this section, you will be familiar with the basics of how to use your EFIS-D100. For details regarding specific procedures (e.g., adjusting display brightness, changing the altimeter setting, setting the clock, etc.) please refer to the EFIS Operation section. Front Panel Layout All normal operation of the EFIS-D100 happens via the front panel. The front panel contains buttons and a display. Buttons – There are six buttons on the front panel of the EFIS-D100.
Product Operation Display The EFIS-D100 display is the most obvious and commonly used output of the device. It is capable of displaying EFIS, HSI, and/or engine data simultaneously. SCREENS AND PAGES The terms in the following bulleted list are used in this section and are defined as follows: Screen/Screen Configuration – Screens consist of one or two pages from the EFIS-D100 or from another DSABconnected Dynon Avionics product.
Product Operation The EFIS-D100 has several pre-defined screen configurations. The basic layout of a screen configuration is represented by one of three icons on D100-series product. The table at right shows the three icons and their meaning.
Product Operation CYCLING BETWEEN SCREENS There are two methods for cycling between pre-defined screens: via the menu and via hotkeys. Screen Cycling Using the SCREEN LIST Navigate to the SCREEN LIST menu by holding button six for at least two seconds when no menu is present (see the figure to the right). Note that if you only press button six momentarily, the display cycles to the next screen in your screen rotation. Use the DOWN▼/UP▲ buttons to move the caret (>). The caret denotes the selected screen.
Product Operation Changing the Screen Rotation You may use the out-of-the-box screen rotation or define your own. If you desire to use the initial rotation, no user configuration is required. If you desire to use a custom cycling order, then user configuration is necessary. To configure a custom rotation, navigate to the SCREEN LIST menu page by pressing button six for approximately two seconds when no menu is present.
button to move the selected screen down in the screen list. Likewise, press the MV UP▲ button to move the selected screen up in the screen list. Menus All interaction with the EFIS-D100 is accomplished through the use of its menu system. The menu system is accessed and navigated via the six buttons located on the front of the unit. PAGE-SENSITIVE MENUS On a screen where no menu is already present, buttons two through five are used to display a menu.
Product Operation Pressing a button either displays another menu or adjusts a parameter. If there is no text above a button, then that button does not have a function in the context of that menu. Occasionally, a button label spans two or more buttons. In this case, any button below the label invokes the command. If a menu contains more options than there are buttons, the MORE label is displayed over button five. Pressing this button shows you the next set of options in the current menu.
Product Operation For example, if you press the BUGS button on the EFIS menu, there are options for HDG, IAS, ALT, and EXIT. Pressing HDG, IAS, or ALT allows the user to configure heading, indicated airspeed, or altitude bugs, respectively. To exit the menu system, press the BACK button as many times as is needed to reach an EXIT button. This varies based upon how deep you are into the menu system. In any menu with more options than will fit on a line, the MORE button displays the rest of the menu.
4. AVAILABLE PAGES The EFIS main pages use various tapes, digital displays, and other indicators overlaid on an artificial horizon. On the 2/3 and full-screen pages, you may also display up to two “info items” on the left and right side of the main page. HSI pages use text and a DG style compass by itself or overlaid with lines and arrows of different colors. Note: HSI pages use data that is obtained from a source external to the EFIS-D100.
Available Pages EFIS Main pages Available in 1/3, 2/3 and full formats The EFIS-D100 default screen rotation includes only 2/3 EFIS pages combined with the various EMS and HSI pages described below. However, you may also choose screen configurations that use 1/3 and full-screen pages. The 2/3 and full-screen pages can display EFIS- and EMS-related info items on the left and right side of the screen.
Available Pages Horizon line, pitch and roll indicators Bounded on the top by blue, and on the bottom by brown, the horizon line behaves in much the same way as a traditional gyro-based artificial horizon. Unlike a mechanical artificial horizon, the EFIS-D100’s horizon has no roll or pitch limitation. The horizon line stays parallel to the Earth’s horizon line regardless of attitude.
Available Pages The CDI is located just above the slip/skid ball when displayed, and behaves much as described in the HSI Operation section on page 6-1. The CDI needle is green when sourced from a NAV radio and magenta when sourced from GPS. When to/from information is available, the center of the CDI is an arrow; when on an ILS, it is a filled-in square. The glideslope indicator is located to the left of the roll scale tape, and behaves much as described in the HSI Operation section on page 6-1.
Available Pages Turn rate indicator Centered just below the heading digital readout, the turn rate indicator displays the aircraft’s current rate of turn with respect to the ground. The magenta bar grows in the direction that the aircraft is currently turning, and is anchored at a white vertical anchor line. The brackets on either side of the bar’s anchor line represent the turn rate which results in a standard rate turn. Turn rate takes attitude into account.
Available Pages During the first 30 seconds of operation, the altitude tape and digital readout are not displayed as the unit needs a small amount of time before altitude measurements are deemed accurate. Elevator trim indicator Located in the lower right corner of the EFIS page, the elevator trim indicator displays the relative trim of the elevator in graphic form.
Available Pages the AOA display. To judge when a stall will occur, remember that the AOA indicator is showing actual AOA, and the stall AOA changes with configuration. Because of this, a stall could occur anywhere inside the yellow range, but will occur at the same point every time given a specific configuration. Refer to the EFIS-D100 Installation Guide for more information on calibrating the AOA indicator.
Available Pages Your airspeed, heading, or altitude is at its set bug value when the bug’s inverted triangle encloses the triangle of the digital readout’s pointer. The altitude bug also acts as an altitude alerter; see BUGS – Setting Bug Markers on page 5-2 for more information. When a Dynon Autopilot is installed and configured, the heading and altitude bugs are repurposed as the target heading (in HDG mode), ground track (in TRK mode), and altitude (in ALT mode).
Available Pages Autopilot Status Indicator When a Dynon Autopilot is installed and configured, an AP Status Indicator is displayed at the bottom left of the EFIS page. It provides information about whether the Autopilot is engaged and what mode(s) it is engaged in. See Autopilot Operation on page 7-1.
Available Pages Times Page Available in 1/3 format There are two different versions of the Times Page. The EFIS version includes two sections of times and the EMS version includes three sections. There are some times that are common to both EFIS and EMS Times Pages. The Times Page is divided into three sections: TIME, TIMERS, and ENGINE TIMERS. Native to both EFIS and EMS, the TIME section shows the present time (both local and Zulu) and can be displayed in either standard or military time formats.
Available Pages Lists Pages Available in 2/3 format This page displays user-defined checklists and data panels to be used for waypoint information, lists of radio frequencies, or other informational purposes. You may define up to twenty-five lists. Each checklist/data panel can contain up to 14 lines of text and 40 characters per line. Checklists/data panels must be defined and uploaded to the EFIS-D100 as described by the Dynon Product Support Program, available at downloads.dynonavionics.com.
5. EFIS OPERATION This section guides you through each of the EFIS main page menu selections and their sub-menus. To enter the EFIS menu system, press any button (except for buttons 1 and 6) directly beneath an EFIS main page. If no EFIS main page is displayed, you must switch to a screen configuration that includes and EFIS main page as described on page 3-4.
EFIS Operation The BARO setting can be changed using the HS34’s VALUE knob, depending on the configuration settings in EFIS > SETUP > HSI > VALUE KNOB. The BARO setting can be changed using the AP74’s VALUE knob, depending on the configuration settings in EFIS > SETUP > AP > VALUE KNOB. The current indicated altitude is preserved across a power cycle. When powered down, the instrument saves the indicated altitude.
EFIS Operation In the HDG/TRK bug menu the value-setting box is displayed in the lower part of the display. Press SEL► to select which digit to change and DEC- and INC+ to change the selected digit. Press the SYNC button to synchronize the heading/track bug to your current heading or track. As you increment or decrement the bug value it rolls over at 360 degrees, returning the value to 001. If you have the heading or track bug displayed, the marker moves left or right along the tape as you change its value.
EFIS Operation The airspeed bug can be adjusted on any EFIS page in the system and is synchronized across all EFIS-based units. When in the BUGS > IAS menu, rotate the AP74’s or HS34’s VALUE knob to quickly change the bug’s set value. ALTITUDE In the BUGS menu, press ALT. Press the TOGGLE button to turn on or off the altitude bug display on the altitude tape. In the ALT bug menu the value-setting box is displayed in the lower part of the display.
EFIS Operation red and yellow as a visual alert. When below the 200-foot window, a rising tone is sounded; when above the 200-foot window, a descending tone is sounded. The visual climb or descend alert clears after recapturing the target altitude or 30 seconds. Flying back inside the 150-foot capture window re-arms the alerter without any user interaction. If your system is configured to output voice via an HS34 or AP74 module, the voice alerts “climb” or “descend” are sounded, instead of tones.
EFIS Operation you display a checklist, the right 2/3 of the screen displays the checklist while the left side displays a 1/3 format EFIS page. See the Dynon Support Program for more detailed information on entering checklists and data panels. It can be downloaded from our website at downloads.dynonavionics.com.
EFIS Operation SETUP – Setting Preferences Enter the EFIS > SETUP menu to make changes to preferences. Many of the settings in this menu should only be changed by the installer, and are described in the EFIS-D100 Installation Guide. The preferences and settings that are relevant to the pilot and in-flight operation are explained below. CHANGE DISPLAYED UNITS In the UNITS submenu, you may change the system-wide displayed units for the following units.
EFIS Operation In a DSAB network, you can only set the Zulu time on the DSAB master, and only if it is not synchronized to GPS time. You can set the local time on all units individually. To change the local clock when moving through time zones or to enter daylight saving time, simply change only the hours (and, if necessary for the time zone, the half-hour offset) for the local time.
EFIS Operation corresponding to one of these options turns the respective onscreen item on or off. The following table summarizes the display item abbreviations and their function.
EFIS Operation Abbreviation GTRK Display Item Ground Track WIND Winds Aloft ASTRND VSI Airspeed Trend Vertical Speed Indicator CDI Course Deviation Indicator 5-10 Function Toggles the display of the ground track indicator on the heading tape. The track indicator is a magenta arrow and is only displayed when the EFIS-D100 is receiving valid GPS data from an external source.
EFIS Operation Abbreviation CRS Display Item Course Pointer TRIM Elevator Trim Function Toggles the display of a “V”-shaped course pointer on the heading tape. Like the CDI, this can only be displayed when the EFIS-D100 is receiving a valid course from the NAV source selected on the HSI page. If the CRS button status displays “Y” and no course pointer is displayed on the heading tape, the EFIS-D100 cannot detect your NAV radio or GPS, there is no active course set, or there is no NAVSRC chosen.
EFIS Operation The voltmeter displays 3 rows of information corresponding to the three power inputs on the EFISD100. The first row, labeled M, displays the Master Switch voltage. The second row, labeled E, displays your optional external backup voltage. The third row, labeled I, displays the EFIS-D100 internal battery voltage. If any of the 3 voltage inputs are not present, 00.0V is displayed for the respective voltage values.
EFIS Operation OAT (Outside Air Temperature) The EFIS-D100 supports the connection of an OAT to its EDC-D10A. If no OAT is connected to the EFIS-D100, or to any other device in a DSAB system, you may manually set the outside temperature. The OAT info item displays 3 lines of text, containing outside air temperature, density altitude, and true airspeed. To use the TAS/DA calculator without an OAT installed, manually enter the outside air temperature in the EFIS > OATSET menu.
EFIS Operation All screens in a DSAB network share a common dim level. Pressing BRITR or DARKR on one unit changes the brightness level on all screens if the change is possible. If you have any D100-series bright screen units in the system, you must press BRITR on any bright screen unit to get the bright screen units to their final step of brightness.
EFIS Operation To start the timer, press START. Once started, the button’s label changes to STOP. To stop the timer, press STOP. To set the down timer, press HOUR, MIN, and SEC to adjust the timer to the desired value. You may not have an up timer and a down timer running at the same time. Multiple Dynon products connected via a DSAB network share one timer. Starting, stopping, or configuring the timer on one instrument causes all other instruments to reflect the change.
EFIS Operation “all data” and “MIN/MAX”. Both logs can be downloaded using the “Retrieve Logged Data” option of the Dynon Support Program. On certain Dynon Avionics EFIS and EMS units, a “SNAPSHOT” log is also recorded and can be downloaded. The snapshot log records the value of all parameters anytime an alert occurs. To activate internal data logging, enter the EFIS > SETUP > DATLOG and set RECORDING to ON. Set the INTERVAL depending on how frequently you wish data to be stored.
6. HSI OPERATION This chapter explains how to use the EFIS-D100’s HSI functionality. Required Connections To display an HSI on the screen, an external receiver is needed. The currently supported data sources are a Garmin SL30 Nav/Comm radio via a serial connection (Nav data), a Garmin GNS-430/530 GPS/Nav/Comm (GPS data), or any GPS that outputs in either NMEA-0183 or aviation format. Please refer to the EFIS-D100 Installation Guide for instructions on how to connect these devices to your Dynon network.
HSI Operation All HSI screens in a DSAB network share their configuration and are identical to one another at all times. Changing the source of information on one HSI page affects all units, as does changing scaling, bugs, or bearing pointers. It is not possible to show a NAV radio on one screen and a GPS on another screen. HSI Display Basics There are three possible sources of information on the HSI page: GPS, NAV, and internal EFIS data.
HSI Operation d. "LOC" in green text. This indication means that the radio is tuned to a localizer. The glideslope scale is visible as well, but may be flagged invalid. e. "BC" in yellow text. This indication means that the radio is tuned to a localizer and is in back course mode. The glideslope scale is visible as well, but may be flagged invalid. Note: when flying a back course on an HSI, no reversal is needed since the CDI indicator spins with the DG.
HSI Operation 6. Winds aloft. This indicator, located at the bottom of the HSI page, appears only when you have GPS data and true airspeed available to the instrument. The arrow is the wind direction relative to your aircraft. It is always the same size and only indicates wind direction. The numbers below are absolute wind direction (magnetic) and absolute wind speed. Below that, labeled as "XW" is the crosswind component of the wind.
HSI Operation externally using the knob that is on the SL-30 when in VOR mode. When in ILS mode, the SL-30 disables the OBS knob, and thus you must use the soft keys below the HSI in order to set the course. When using the HS34 you can set the OBS using the COURSE knob. When properly configured, the HS34 sends course information to the NAV radio, just like a mechanical HSI or CDI does.
HSI Operation 6. Glideslope flag. This appears when the radio is tuned to a localizer and the glideslope is not valid. When this is active, there is no indicator mark on the GS scale. 7. Bearing To indicators. These arrows show you the bearing to the active and standby VORs. This is the direction that you would need to fly to go directly from where you are to the transmitter. When flying directly on course, your bearing and course lines overlap one another.
HSI Operation GPS Overlay The figure at right shows an HSI page with information sourced from a GPS receiver while the GPS has an active flight plan between two points. The various elements are described below. 1. Text displays. In this area a variety of information is displayed in text format. Displayed here is the ground track (TRK), the course (CRS), ground speed (SPD), distance to next waypoint (DTW), and up to two bearing pointer selections. 2. Course indicator.
HSI Operation 4. To indicator. There is no "from" indication with GPS data, since the GPS is the source of the course line. This arrow always points the same way as the course line, as indicated in the small oval in the previous figure. 5. Vertical Guidance Indicator. When connected to a Garmin 396/496 the glideslope indicator mimics the GPS’s vertical guidance display. This appears only when a VNAV profile is active on the GPS.
HSI Operation When the HS34 is hooked to a GPS unit via ARINC-429, the system can read the scaling from the ARINC-429 connection. When connected this way, the scaling auto-updates and follows the GPS. The indication on the screen for mode and range should match the mode and range of the GPS at all times. When in this mode, the range is not limited to just 5/1/0.3nm, as the GPS may slide between scales, so it would not be unexpected to see a number such as 0.8 on the screen.
HSI Operation BUG - This is the same menu as EFIS > BUGS > HDG. This menu allows you to adjust and toggle a heading bug that appears on the DG display as well as the EFIS heading tape. The heading bug can be adjusted at any time by rotating the HS34’s HEADING knob. If the bug is currently toggled off, rotating the HEADING knob causes the bug to be displayed on the HSI display. To sync the bug to your current heading, press the HEADING knob briefly.
7. AUTOPILOT OPERATION This section guides you through the indicators and operation of Dynon’s EFIS-based Autopilot (AP) system. This section assumes that the AP has already been installed, configured, and tuned according to the EFIS-D100 Installation Guide. Additionally, it assumes that you are already familiar with the operation of the EFIS-D100 menu system, documented throughout this guide.
Autopilot Operation normal business hours, the Forum is a convenient way to interact with Dynon Avionics Technical Support. The Forum also allows online sharing of wiring diagrams, photos, and other types of electronic files. All Dynon instruments connected via DSAB must be running the same firmware version. This applies to the servos and AP74 as well, which are updated via the Bus Master EFIS.
Autopilot Operation only a pitch or only a roll servo is installed, that axis’ indicator is shown just to the right of the “AP:” display. When either the roll or pitch axis is engaged, the entire indicator has a black background. The following table describes the different states for each axis and the relevant text descriptions in the AP status indicator.
Autopilot Operation AP Status Indicator Modes AP State Roll Display Pitch Display Warning: Servo slipping Mode display with yellow background Mode display with yellow background AP Status Indicator Errors AP State Warning: Servo has been calibrated but not tested (See: SETUP > AP > SERVO TEST) Warning: Airspeed outside min or max airspeed. See: SETUP > AP > PITCH SERVO. Warning: Servo error condition detected, or servo not found. Check DSAB configuration, wiring, and servo power.
Autopilot Operation If, while flying in HDG mode and compass data is lost, the AP fails over to TRK mode (if valid GPS data is present). If, while flying in NAV or TRK mode and GPS data is lost, the AP fails over to HDG mode (if valid compass data is present). BUGS DISPLAY (LOWER RIGHT CORNER) Whenever either the heading or altitude Bug is toggled ON (via the BUGS menu or the AP74) its current value is displayed in the lower right corner of the EFIS page.
Autopilot Operation HDG: HEADING MODE – ROLL SERVO When the AP is engaged in Heading Mode, it uses the roll servo to control the aircraft’s magnetic heading, with the goal of following the heading bug. You may adjust the heading bug, causing the AP-controlled aircraft to turn toward the new target heading. The AP’s goal in the roll axis is to align the triangle of the numeric magnetic heading box with the inverted triangle of the heading bug.
Autopilot Operation NAV: VOR NAVIGATION MODE – ROLL SERVO NAV/VOR mode is available whenever a NAV radio source is selected as the HSI page’s NAVSRC and the CDI reads TO or FROM. NAV/VOR mode is indicated by the annunciation “VOR” in the AP LAT:LON status. NAV/VOR mode intercepts from any position relative to the station and flies the radial specified on the OBS. It may not be able to complete an intercept within 10 miles if the aircraft is far from the desired course.
Autopilot Operation ALT: ALTITUDE MODE – PITCH SERVO When the AP is engaged in Altitude Mode, it uses the pitch servo to control the aircraft’s aircraft’s altitude. You may adjust the altitude bug, causing the AP-controlled aircraft to climb or descend toward the new target altitude at the average vertical speed defined during setup. In Altitude Mode, the AP’s goal in the pitch axis is to align the triangle of the numeric altitude box with the inverted triangle of the altitude bug.
Autopilot Operation AP Control Methods The AP can be controlled and monitored in a number of ways (described in detail in the sections below): EFIS menus: Set HDG or TRK and ALT bugs (AP targets), change AP modes, engage/disengage AP AP74 AP Control Panel: Set HDG or TRK and ALT BUGS (AP targets), arm AP modes, engage/disengage AP HS34 HSI Control Panel: Set HDG or TRK and ALT BUGS (AP targets) Disengage/Control Wheel Steering (CWS) pushbutton: engage/disengage AP EFIS Autopilot Control This sect
Autopilot Operation (HDG, TRK, or NAV)OFF/ON: The menu label also reflects the currently active lateral mode, and whether or not the AP is engaged in that mode. Pushing this button toggles between ON and OFF, activating and deactivating the roll servo in the specified mode. ALT and HDG or TRK modes can be enabled independently of each other. When the Autopilot is engaged in HDG or TRK mode, the heading bug is synchronized to the current heading or ground track, respectively.
Autopilot Operation AP74 Autopilot Control This section describes how to control the Autopilot via the AP74. When an AP74 is installed, the Autopilot can still be controlled via the EFIS-based AP menu. The AP74 has all the functionality of the EFIS > AP menu, while providing a more efficient way to interpret and use the Autopilot. It also provides some additional features, such as the ability to arm modes prior to engagement, and easy adjustment of AP targets via its dedicated knob.
Autopilot Operation AP Button: When its indicator is off, pressing the AP button engages the AP in the pre-armed mode(s) indicated by the Horizontal and Altitude Mode button indicators below. Depending on how you have configured bug synchronization, the AP may synchronize the bugs for pre-armed HDG, TRK, or NAV modes upon pressing the AP button. Read Pre-select Configuration on page 7-14 for more details on configuring this behavior for your needs.
Autopilot Operation When its indicator is on, pressing the button disarms/deactivates the roll servo and turns off the button’s indicator. NAV Button: When its indicator is off, pressing the NAV button arms the roll servo in Navigation Mode and turns on the indicator. If the AP is already engaged, pressing the NAV button activates the roll servo in Navigation Mode. In Navigation Mode, the AP flies the aircraft based on the navigation information displayed on the HSI page.
Autopilot Operation FIRST ACTION mode. A second push of the VALUE knob within 5 seconds after rotating the knob de-activates the VALUE knob and closes the pop-up window. If there is no further action (either a knob push or knob rotation), the VALUE knob automatically de-activates (times out) after 5 seconds and closes the pop-up window.
Autopilot Operation NEVER: The HDG and ALT bugs are never automatically modified by turning on the AP or changing AP modes. Be aware that the bugs are highly likely to be set far away from the current heading and altitude at the time of AP engagement; this will result in the AP immediately commanding a turn and a climb or descent at time of engage. When using this mode, we recommend that you verify the EFIS’ bugs settings prior to EVERY Autopilot engage.
Autopilot Operation HOLD TO ENGAGE Setting HOLD TO ENGAGE to Y allows you to engage the Autopilot by holding the Disengage/CWS Button for more than 2 seconds. This allows for a convenient alternative to engaging the Autopilot via the menus and/or AP74 AP button. Default is N. When this mode is active, anytime the autopilot is disengaged you can engage it by pressing and holding the Disengage/CWS Button for more than 2 seconds, then releasing.
Autopilot Operation If CWS mode is engaged and during this time airspeed exceeds AIRSP MAX (SETUP > AP > PITCH SERVO) releasing the AP Disengage/CWS Button will not re-engage the AP. The Autopilot can only be re-engaged when airspeed is below AIRSP MAX. Optional Preflight Checklist If you desire an Autopilot preflight test, the following can be used as a baseline. 1. 2. 3. 4. With the circuit breaker for the servos powered OFF, test the controls for proper operation of the control surfaces.
8. ALERTS Alarm Indicators Any time a built-in or preconfigured alarm set point is exceeded, you are alerted to the fact via the alarm bar and menu at the bottom of the screen. When an alarm is triggered, the following things occur: A red alarm bar appears at the bottom of the screen with a message identifying the out of range measurement Below the alarm bar, the alarm menu gives you options for what to do next.
Alerts When configured for voice alerts, the HS34 reads out an alarm that occurs, such as “CHT 1 HIGH” or “LOW FUEL.” These voice alarms can be acknowledged and silenced just like the EMS tone. SHOW PAGE If the alarming measurement is not displayed on your current screen, or is available on a page which displays it better, a SHOW [PAGE] button is included in the alarm menu. [PAGE] is replaced with the name of the actual page that is displayed when you press the button.
Alerts Multiple Alarms Any time multiple alarms occur in quick succession, they are handled in the following way: 1. 2. 3. 4. 5. Each numeric value and gauge posts its alarm by turning red, blinking, bringing up the alarm bar, and triggering the external light and audio alert. Alarm messages in the alarm bar are stacked into memory and presented in the order in which they occurred, unless a higher priority alarm occurs. Removal of the Alarm Bar requires separate pilot acknowledgement of each alarm.
Alerts NETWORK CONNECTION LOST: This error means that all network communication has stopped. In this event, no instruments share data or settings until the cause of the communication problem is resolved and all units are power cycled. Individual units that are powered on and functioning continue to function using their internally-derived data.
9. APPENDIX This appendix contains information not covered in the main section of the manual.

See the following list of alert messages displayed by the EFIS-D100.
Appendix Alert Message ATTITUDE RECOVERING… TEMPERATURE UNSTABLE TEMPERATURE OUT OF SPEC Description This alert is displayed anytime the unit is rotated at a rate faster than 150 degrees/second or the unit is powered on with airspeed applied. Rotating the unit faster than this threshold will saturate the gyros, leading to potentially erroneous display. The blue/brown horizon indication will turn grey and black to indicate that the artificial horizon is not currently a trusted source.
Appendix Alert Message INTERNAL BATTERY LOW Description You will see this alert only when operating the unit solely off the internal backup battery. When its voltage has dropped below a certain threshold, you will see this alert. Additionally, the voltmeter will be displayed onscreen. When you see this alert, it is advisable that you turn the unit off by pressing the POWER button in Main Menu 1. REMOTE COMPASS NOT DETECTED The EFIS-D100 is unable to communicate with the EDC-D10A.
Appendix Alert Message OAT SENSOR NOT DETECTED Description This alert appears when the EFIS has an OAT connected and then loses that connection for some reason. Either the EDC-D10A has become disconnected, or the OAT sensor itself has become disconnected from the EDC-D10A. EFIS-D100 Pilot’s User Guide End condition Double-check your wiring between the EFISD100 and the EDC-D10A as well as that of the OAT sensor.
