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.

POWER

The EFIS-D100 requires between 10 and 30 volts DC for operation and has inputs for an external backup power supply and a keep-alive voltage. It is acceptable to have the EFIS-D100 turned on during engine start.

The EFIS-D100 can be ordered with an optional internal battery which allows the instrument to continue to operate in the event of an external power failure. This lithium-ion battery is rechargeable and is managed by the EFIS-D100. If the always-on Keep Alive circuit is connected, the EFIS-D100 continues to charge its internal battery even if the instrument is turned off. This ensures that your internal emergency battery is always fully charged. Under normal conditions, the internal battery should have a voltage between 13 and 16.8 volts. When the battery’s voltage drops below 13 volts, the EFIS-D100 displays a low battery warning. When new, a fully charged internal battery is rated for a minimum of 1.5 hours of normal operation with the EFIS-D100. If the EFIS-D100 has switched to its internal emergency battery due to a power loss in your aircraft, it is advised that you land as soon as possible.

EFIS-D100 Pilot’s User Guide

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.

DYNON SMART AVIONICS BUS

If you have multiple Dynon Avionics products in your aircraft, they may be networked together via the Dynon Smart Avionics Bus (DSAB). Units networked via DSAB have the ability to transmit information to each other. Any product's data can then be viewed on any other screen in the DSAB network. For example, an EFIS has the ability to display engine monitor information if it is connected to an EMS or FlightDEK-D180.

Note that the failure of a unit in a DSAB network may cause the loss of some or all data shared between units. In the above example, if the connected EMS/FlightDEK-D180 were to fail, the EFIS would no longer be able to behave as an engine monitor. For more information on DSAB-specific alerts, refer to the DSAB Alerts section on page 8-3.

OUTPUTS

The EFIS-D100 has an output to drive an external customer-supplied audible device for AOA (if installed) and altitude alerts.

A serial output is also provided for serial altitude encoder data. An optional Serial-to-Gray Code Converter is available for connection to Mode C Gray Code transponders.

A connected HS34 or AP74 can output voice annunciations for many of the alerts generated by the EFIS-D100.

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. The AP74’s buttons control the Autopilot operation mode (Heading Hold, Track Hold, GPS horizontal navigation, altitude hold), and allow you to engage and disengage the Autopilot.

When an HS34 is configured to control the EFIS-D100, its VALUE knob changes values when in various EFIS menus. When no menus are displayed the HS34 can adjust the barometer or altitude bug. The HS34’s HEADING and COURSE knobs affect their respective parameters on the HSI page. The HS34’s GPS and NAV buttons cycle through the available GPS and NAV sources connected to it.

ADAHRS Operation

The primary flight instruments on your EFIS display are generated using a group of calibrated sensors. All of them are solid state – that is, there are no moving parts. These sensors include accelerometers, which measure forces in all three directions; rotational rate sensors, which sense rotation about all three axes; pressure transducers for measuring air data; and magnetometers on all three axes for measuring magnetic heading. These sensors form the core of Dynon’s Air Data Attitude and Heading Reference System (ADAHRS).

The table below describes which inputs and sensors are used within the EFIS to generate the different displayed instruments. It is not meant to enable in-flight troubleshooting, but is provided to convey how much of an integrated system your EFIS is.

ATTITUDE CALCULATION

The EFIS-D100 artificial horizon display (attitude) is generated via a complex algorithm using a multitude of sensors. Your EFIS attitude is not reliant on any single external system. It

can provide an accurate attitude - even in the event of airspeed loss (due to icing or other blockage) - via a redundant GPS aiding source. In normal operation the instrument uses airspeed to provide superior attitude accuracy. If a problem develops with your airspeed reading,

a properly connected and configured GPS source acts as a substitute. When in this mode the instrument continues to provide accurate attitude.

*If a GPS is present upon the loss of airspeed, the EFIS-D100 uses the GPS ground speed in its attitude calculation. When in this mode, a magenta GPS ASSIST message is displayed over the horizon and the ground speed is displayed below the IAS indicator (as shown at right). If the connectivity with the GPS fails while in GPS assist mode, the attitude continues to be displayed, using the last known GPS ground speed as a reference. This mode is flagged on the horizon with a yellow CROSS CHECK ATTITUDE message. In the very rare case that

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. The aircraft’s compass must be installed correctly, calibrated, and operating well in all attitudes.

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.

Page – A page is a section of the screen that contains a collection of related data. Pages may occupy the total area of the screen (i.e., 100%) or share the screen with other pages (e.g., 2/3, 1/3 split). Pages that occupy 1/3 of the screen area are sometimes abbreviated versions of their full size (100% or 2/3) counterparts.

Screen Rotation – The rotation is the list of screen configurations which can be cycled to via the hotkeys. Your rotation is usually smaller than the total list of available screen configurations.

Screens contain one or two pages and pages contain groups of similar information.

3-2	EFIS-D100 Pilot’s User Guide

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.

The predefined screen configurations with their respective icons are as follows:

Icon	Left Page Area		Right Page Area

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. Press GOTO► to remove the SCREEN LIST and display the selected screen. If you wish to stay on the same screen, you may either select your currently displayed screen with the caret and press GOTO►, or press CANCEL.

Screen Cycling Using Hotkeys

With no menu displayed, press button one to cycle to the previous screen in your rotation. Likewise, press button six to cycle to the next screen in your rotation (see the figure on the next page). Cycling via hotkeys only allows you to display screens that are in your screen rotation. They are meant to give you quick access to the screen configurations that are most important to you. If you wish to access screens that are not in your rotation, use the SCREEN LIST as described above.

Hold two seconds

With no menus displayed, pressing button six for two seconds displays the SCREEN LIST menu, from which you may switch to, and set up, various screen configurations.

3-4	EFIS-D100 Pilot’s User Guide

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. Press SETUP, then press ROTATN to display the menu used to change the boot and rotation screen. Scroll through the pre-defined screens using the DOWN▼/UP▲ buttons.

Press the BOOT* button on any selected screen configuration to make it the screen that is shown immediately after the instrument is turned on. Only one screen may be designated as the boot screen. Next, press the TOGGL↕ button on any selected screen to toggle the “↕” icon. All screens that show the “↕” icon are included in the rotation. Any screen in the rotation may be accessed via the button one and six hotkeys. Press BACK to save any settings.

prev. screen		next screen

Buttons one and six cycle to the previous and next screens, respectively.

Changing the Screen List Order

You may wish to change the order in which screen configurations are displayed in the SCREEN LIST, thus changing the order they are cycled to via hotkeys. To do this, navigate to the SCREEN LIST menu page by pressing button six for approximately two seconds when no menu is present. Press SETUP, then press ORDER to display the menu used to change the screen order. Scroll through the pre-defined screens using the DOWN▼/UP▲ buttons. Press the MV DN▼

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. With no menu displayed, pressing any one of these buttons causes the menu for the page above it to show at the bottom of the screen. For example, if a screen is divided into two pages with the left page occupying 2/3 of the screen and the right page occupying 1/3 of the screen, then pressing EFIS-D100 buttons two, three, or four (all below the left 2/3 of the screen) displays the main menu for the left page and pressing button five (below the right 1/3 of the screen) displays the main menu for the right page (see the figure to the right).

FUNCTIONALITY

A menu consists of two rows of gray boxes containing text. The upper row contains one tab that denotes the currently displayed menu. The lower row contains six labels that denote the function of the button below it. Many of the onscreen elements move up to avoid the menu. This prevents the menu from obscuring useful data while it is up. Upon exiting the menu, the screen returns to its normal appearance.

The configuration of the pages on the screen determines which buttons are used to display a page's menu.

3-6	EFIS-D100 Pilot’s User Guide

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.

In any menu, press the BACK button to return to the previous menu and save any changes. In all top-level menus, button six is the EXIT button. Pressing EXIT removes the menu system and moves many of the onscreen elements down to their original positions.

FLOW

Each page has its own main menu, which may contain options for navigating to other menus or choosing and adjusting parameters. For example, the EFIS Main Page menu contains an EFIS menu tab and button labels for MENU►, BARO, BUGS, LISTS, MORE, and EXIT. Pressing MORE reveals the rest of the EFIS menu. This menu contains options for SETUP, INFO, DIM, TIMER, MORE, and EXIT. Pressing MORE on this menu simply returns you to the first part of the EFIS menu.

Each menu consists of labels above each button denoting their function.

In all top-level page menus (EFIS and HSI), the leftmost button is the MENU button. If you have opened up the left page’s menu, the label reads MENU►. Pressing the button switches the menu to display the right page’s menu, and the label switches to read ◄MENU. The arrow on this button always points to the side of the screen whose menu is displayed when pressing the button.

EFIS-D100 Pilot’s User Guide

3-7

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.

DESCRIPTIONS IN THIS GUIDE

In any menu with more options than will fit on a line, the MORE button displays the rest of the menu.

Throughout this guide, the “>” character is used to indicate entering a deeper level of the menu system. For example, “EFIS > INFO > LEFT” indicates entering the EFIS menu, pressing MORE, then pressing INFO, and then pressing LEFT to enter the left info item menu. Note that the MORE button is not included in the sequence, since pressing MORE reveals more options in the same level of the menu system.

3-8	EFIS-D100 Pilot’s User Guide

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. Refer to the EFIS-D100 Installation Manual for a list of compatible equipment.

Note: EMS-based pages use data that is obtained from Dynon’s EMS products. You may only display these pages on your EFIS-D100 if you own a Dynon EMS-based product, and the two units are connected via DSAB. Refer to the EFIS-D100 Installation Manual for details regarding proper connection between Dynon products and other devices in your system. Please see your EMS-based product’s Pilot’s User Guide for information on configuring the various displays sourced from it.

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 EFISand EMS-related info items on the left and right side of the screen. You can enable any of the non-default EFIS screens as described in the Changing the Screen Rotation section on page 3-5. Some of the displayed items described below may not be onscreen, depending on whether or not they have been enabled in the CLUTTR menu.

Beginning with firmware revision 3.0, Dynon adopted a dramatically different EFIS display format than it had previously used. If your EFIS display does not resemble the layouts shown at right, first ensure that you are using firmware version 3.0 or higher. Then, ensure that the setting at EFIS > SETUP > STYLE is set to MODERN. If you prefer the previous display style, you can change this setting to CLASSIC. The classic display format is documented in previous revisions of this manual, available on Dynon Avionics’ website at docs.dynonavionics.com. No further development will occur on the classic display format.

The following sub-sections describe the displayed items in detail.

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. The parallel lines above and below the horizon line are the pitch indicator lines, with each line indicating 5 degrees of pitch. The end of each 10º pitch indicator line has a hooked barb that points towards the horizon line to aid attitude awareness.

The roll scale has tic marks at 10, 20, 30, 45, 60, and 90 degrees of roll. In the CLUTTR menu

(described on page 5-7), you can choose between a stationary roll indicator and one that rotates along with the horizon. The stationary roll indicator (type 1 in the EFIS > SETUP > CLUTTR > ROLL menu) has an internal arrow which moves to stay perpendicular to the horizon, like a jet EFIS presentation. The moving roll indicator (type 2) rotates the scale about a stationary internal arrow which points to the current roll angle on the scale, like most mechanical attitude instrument presentations.

Please see the ADAHRS Operation section on page 2-3 for important information about the theory of operation for the attitude and external data sources.

CDI/Glideslope Indicators

When the EFIS-D100 is receiving CDI or glideslope information from a GPS or NAV radio, they can be displayed on the main EFIS display as well as the on the full HSI page (as described in the HSI Operation section on page 6-1). The data source is chosen on the HSI page using the NAVSRC button; the EFIS and HSI CDI/GS displays are always synchronized to the same source. There is no way to change the source on the EFIS screen.

On the EFIS page, these two items are enabled via the EFIS > SETUP > CLUTTR menu under a single item, which can be set to either CDI:N, CDI:Y, or CDI+GS.

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. The GS needle is green when sourced from a NAV radio and magenta when sourced from GPS, and appears only when tuned to an ILS or a GPS source with vertical guidance.

Due to screen space limitations, turning on the glideslope prevents a left info item from being displayed on the 2/3- screen EFIS page. Additionally, at extreme roll angles, the glideslope is hidden to provide space for other screen elements.

Stabilized heading tape and digital readout

Located at the top of the EFIS page, the heading indicator functions much like a standard slaved directional gyro. North,

East, South, and West directions are labeled on the tape, “N,” “E,” “S,” and “W,” respectively. The digital readout displays your current heading, while the surrounding tape scrolls beneath its arrow. You may set a yellow bug on this tape as a heading reminder. The pointer in the digital readout is hollow to allow the GPS ground track indicator, displayed as a magenta arrow, to show through. A difference between the ground track arrow and the current heading indicates that some wind is present. The currently set course heading is represented by a “V,” colored green when sourced from a NAV radio and magenta when sourced from GPS. When the CDI is centered, aligning the ground track pointer within the course pointer compensates for all wind and takes you directly to the waypoint or VOR. For course and ground track to be displayed on the heading tape, they must both be enabled in the CLUTTR menu.

Like a conventional gyro-stabilized magnetic compass, magnetic heading reacts immediately to turn rate so that heading changes are reflected immediately. It then uses magnetometer data over the long term to ensure that it remains correct. Additionally, heading is corrected for attitude so that it is accurate as you pitch and roll.

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. This means that even when you are highly banked, it still shows rate of turn in relation to the aircraft’s heading.

The turn rate indicator is scaled to indicate a 6-second heading trend. In the example above, the trend indicator is showing that the aircraft will be pointed at 17º in 6 seconds if the rate of turn does not change.

Altitude tape, digital readout, and VSI

The altitude tape scrolls beneath the altitude digital readout and arrow. The digital readout’s digits scroll up and down, simulating an analog altimeter and giving a sense of the direction of movement. Thousands of feet are displayed using large numbers while hundreds of feet are displayed in smaller numbers. The EFISD100 accurately displays altitudes from -1200 to 30,000 ft (-365 to 9144 m).

The graphical Vertical Speed Indicator is located next to the altitude tape. The magenta bar grows in the direction of – and in proportion to – the rate of climb or descent. The numbers on the scale represent thousands of feet per minute. In the CLUTTR menu, the VSI scale can be set to display 1000 ft/min, 2000 ft/min, and 4000 ft/min. The 2000 ft/min scale is linear throughout the range, while the 1000 ft/min and 4000 ft/min are non-linear as shown on the scale. When set to display 2000 ft/min, the VSI bar is scaled to indicate a 6-second altitude trend based on its position with relation to the altitude bar. When set to display 4000 ft/min, the VSI bar is scaled to indicate a 6-second trend only up to 1000 ft/min. When set to display 1000 ft/min, the VSI bar is scaled to indicate a 12-second trend up to 500 ft/min.
