Improved: The airspeed indicator now updates more smoothly at lower airspeeds.
Fixed: Magnetic heading calibration no longer sensitive to flight attitudes that are signifigantly different than those experienced in level flight. This primarily resulted in less than optimal calibrations in some taildragger aircraft. Performance will not change until a heading calibration is performed after an upgrade to 5.6.0.
Fixed: Sensor type 10 sensor characterization for UMA 1BX Oil Temperature sensors.
Fixed: Autopilot NAVSRC lost messages which caused the autopilot to drop down from NAV to TRK or HDG mode.
Fixed: Autopilot altitude hold that was offset by tens of feet from the desired target. Existing altitude offsets may take a few minutes of straight/level AP flight to self-calibrate out.
Improved: Autopilot tolerance of EFIS installations that contain higher than ideal vibration levels.
Improved: Rotax oil temperature fluctuations smoothed out (sensor type 4).
Fixed: Minor oil pressure display bug introduced in 5.4.2.
Added: Support for new Kavlico brand pressure sensors sold by Dynon.
Fixed: SETUP>SPDCAL feature for improving IAS accuracy at very low airspeeds.
Improved: Oil pressure filtering.
Added: Support for alternative 3rd party two-wire oil temperature sensors. See the support wiki for sensor details.
Improved: Autopilot pitch axis control algorithms enhanced for better performance. See updated Installation Guide for details on new adjustments that can be used to tune pitch performance.
Support Program Only: Improvements to support firmware upgrades in OEM installations such as Vans Aircraft that use locked settings files to distribute settings during firmware updates. All other customers unaffected. There has been NO CHANGE to the underlying firmware files from 5.3.
Improved: An alternate set of autopilot control algorithms which may improve roll performance in some aircraft. To try this mode simply set TRN RT LMT to 0. The autopilot will more directly control bank angle instead of targeting a specific turn rate. The maximum bank angle that the autopilot allows continues is still limited by the BANK LIMIT parameter. In this mode, set the BANK ANGLE LIMIT to the maximum value you want the autopilot to use in a turn.
Improved: Jabiru oil temperature sensor characterization
Fixed: Multiple EFISs+AP74 configurations no longer susceptible to rebooting. This fix is the firmware-based solution mentioned in this forum post.
Fixed: Oil pressure sensor type 4 now shows "---" instead of a high temperature when the sensor is electrically disconnected.
Added: Metric vertical speed info item (digital number) is now expressed in meters per second to better match the graphical tape version, which is in tenths of meters per second.
Improved: Autopilot GPS-to-HDG mode drop-downs reduced when GPS data goes momentarily bad.

Note: It is no longer recommended that Keep Alive be connected EFIS and EMS products.
Added: %SLP parameter in SETUP > AP > STATUS. Used for debugging cumulative servo slips when using the AP.
Added: Autopilot GPS Roll Steering. AP will now fly ARINC ROLL commands (GPS Steering) if the GPS provides those commands. ROLL steering will be used any time roll commands are present and AP GPS/NAV mode is selected.
Added: Autopilot status display on the 10 series' HSI page.
Added: Pitch and roll target preselect for the autopilot when used with the AP74/76. See the menu EFIS>SETUP>AP>AP74/76 SETTINGS, BUGS SYNC and CLEAR MODES ON DISENGAGE settings.
Added: Ability to disable altitude alerter audio. See EFIS>BUGS>ALTALM or ALTOFF.
Added: Autopilot NAV/VOR and NAV/LOC tracker.
Added: Data log files now have servo position and HSI parameters (NAV and BRG sources, selected course, CDI, to/from flag, glide slope, bearing pointers, dist to waypoint/dme).
Added: Display of the value knob (HS34 or AP74) setting box on all DSAB peers.
Added: GPS assist mode to ADAHRS algorithm. See the press release on our home page for details.
Added: The word "altitude" for the altitude alerter level-off alert (when audio is wired to HS34 or AP74).
Fixed: Holding the heading knob on an HS34 did not toggle the heading knob off.
Fixed: SL30 BTS now correctly reflects standby radio bearing
Fixed: Pressing and holding the COURSE knob would not properly sync the course pointer to the current bearing. Instead it would sync to 360.
Fixed: Bearings are independently selectable from NAV sourse when an HS34 is present in the system.
Fixed: Course can now be changed when an EFIS is hooked to an SL30 without an HS34 installed, and the SL30 is tuned to an active LOC or ILS.
Fixed: Display glitch on the HSI page that would momentarily display GPS0 or NAV0.
Fixed: Downloaded data log files had incorrect data for month, pitch force, and pitch trim fields.
Fixed: Nav order and GPS order may not be preserved over a power cycle.

Fixed: The display order of the bearing source pointers on the HSI page was not honoring the Nav and GPS order lists.
Fixed: When multiple GPS sources were connected to a DSAB system that did not contain an HS34, only the GPS connected to the DSAB master would be displayable.
Fixed: External tone not triggered with AP74.
Fixed: In rare instances the internal clock could get reset between power cycles, in some of these cases it was possible that the internal battery would be discharged as well.
Fixed: Possible incorrect display of available autopilot modes in the modes menu when communication with EDC-D10A is lost.
Fixed: A display problem with the EMS flaps info item.
Fixed: Display problems on the Fuel Computer page when tank name AUX is used.
Fixed: TRPRST button did not appear on TIMES page.
Improved: Accuracy of G-Meter in installations with significant panel tilt.
Improved: Autopilot out of trim indication.
Improved: GPS glitch detection inhibits invalid GPS data (groundspeed, position, ETC?) from being used or displayed by autopilot, HSI, etc.
Added: A warning is displayed if a magnetic calibration is attempted without first setting the magnetic inclination and intensity.
Added: Ability to configure an EMS contact input as a stall indicator. If AOA selected as alarm type, then audible stall warning triggered on contact activation. See: EMS > SETUP > EMS CONTACT 1/2 > ALARM
Added: Ability to perform incremental data log downloads.
Added: Alarm light output (pin 29 on EMS D-37 connector) can be repurposed as a dim control for other devices in aircraft. The dimming output is directly tied to the brightness of the screen, configured in the DIM menu. See: EMS > SETUP > GLOBAL > ALARM CONFIG > LGT BHVR.
Added: AOA voice alert added to HS34 and AP74. When SETUP > HSI/AP > AUDIO ALERTS > AOA is set to EXT VOICE the word "stall" is repeated in addition to the efis tonal output. When set to EXT TONE only the control panel generates the progressive tone. If HS34 or AP74 fails, setting reverts to EFIS TONE for direct audio output from EFIS. When set to EFIS TONE only the efis progressive tone is generated.
Added: Audible 3-tone alert on autopilot disengage, if no external voice device (HS34/AP74) installed.
Added: Data logging for selected EFIS and GPS parameters. See Support Program help for data log extraction procedure. See EFIS > SETUP > DATLOG.
Added: Elevator trim indication to the EFIS page.
Added: Support for Dynon Autopilot
Added: Support for new actively powered oil pressure sensor that comes preinstalled on newer Rotax 912 motors.
Added: Support for optional AP74. Has some functions of HS34 (audio alerts, including "Autopilot Disconnect"; VALUE knob), as well as dedicated Autopilot controls.
Fixed: Alert on HS34 contacts now works correctly.
Fixed: CDI would still appear on EFIS page even when EFIS NOT DETECTED message was displayed.
Fixed: Contact state indications reversed.
Fixed: Coolant pressure units mismatch.
Fixed: Erratic CDI as course is being adjusted with a Garmin 430 (or similar) connected.
Fixed: HS34 not handling positive mag var correctly.
Fixed: HSI with GPS input "blinks" on DSAB-connected slave screens.
Fixed: If MAP and/or RPM are set to DISPLAY: OFF in EMS, they will not display as EFIS info items. See: EFIS > INFO > ENGINE and EMS > SETUP > SENSOR > TACHOMETER/MANAIFOLD PRES > DISPLAY.
Fixed: Pressing SYNC in any of the EFIS > BUGS menus now correctly activates AND syncs the bug simultaneously.
Fixed: Pushing BRG SRC would not always allow the bearings to be adjusted.
Fixed: Re-configuring the DSAB network from a new Bus Master EFIS when another Bus Master was in the system would fail.
Fixed: Screen brightness could be "stuck" at a very dim setting if an HS34 was present and then went offline.
Fixed: Serial inputs (GPS/SL30) connected to a screen when an HS34 is also connected will be properly ignored with fail-over if the HS34 fails.
Fixed: SL30 BTS reflected BTA value.
Fixed: Tach time accumulation was wrong in some instances when the left and right PULSES/REV settings were different.
Fixed: Timers now sync correctly across DSAB.
Fixed: Voice alert test behavior fixed when tested from an EMS product with an HS34 installed.
Fixed: VSI scale display incorrect with meters and 1K scale.
Improved: DSAB status messages improved to include ACTIVE, UPGRADE REQ, LOST PEERS, STANDALONE, and OFFLINE. See: EFIS > SETUP > DSAB > STATUS
Improved: EFIS and EMS loading screens display more helpful information and support phone number.
Improved: Garmin 480 GPS/NAV compatibility.
Improved: HS34 VALUE knob functionality updated to match AP74. See: EFIS > SETUP > HSI > VALUE KNOB. Can set REQUIRE PUSH to prevent unintentional changes to ALT or BARO mode. Can set FIRST ACTION to set the first parameter (ALT or BARO) in button push rotation. Bugs can be set without entering BUGS menu. Removed IAS bug from the values affected by the VALUE knob. A pop-up value window appears when adjusting a value with HS34.
Improved: Malformed AvMap NMEA data should be handled better, resulting in magnetic variation being back-calulated from other values when it is not explicitly set. This allows a correct magnetic bearing and course to be displayed. AvMAP must have NMEA set to "processed."
Improved: Modified percent power calculation for Lycoming and Continental engines to account for engine RPM red line, not compression ratio. When EMS > SETUP > GLOBAL > ENGINE TYPE is set to LY/CON, then the Tachometer HI RED/YEL parameter is factored into the percent power calculation. See: EMS > SETUP > SENSORS > TACHOMETER > HI RED/YEL.
Improved: Pressing HEADING knob button no longer toggles the HDG bug on/off. HEADING button press now acts as a SYNC of HDG bug to current heading. Pressing and holding HEADING toggles the heading bug on.
Improved: VSI display jitter when at low speeds.
Fixed: Vulnerability during power down on EFIS and FlightDEK products.
New build with EMS-only changes
Added: 1/3 HSI on left, 2/3 EMS on right screen combination.
Added: EMS GP input can now accept an OAT for monitoring a user-named temperature.
Added: EMS General Purpose Thermocouple input can now accept a type J or K thermocouple for monitoring a user-named temperature.
Added: 1/3 EMS on left, 2/3 EFIS on right screen combination.
Added: Support for HS34 HSI Expansion module.
Improved: Various HSI page changes to support HS34 and user feedback about legibility of display elements.
Improved: EMS can now use GPS altitude for % power calculation.
Improved: Vertical guidance indicator now matches Garmin 396/496 indicator when receiving VNAV information.
Improved: EMS data can now be logged internally at 1, 10, 30, or 60 second intervals.
Improved: Back course flag on HSI page is now yellow.
Improved: Manually set OAT (available when an EFIS does not have an OAT probe hooked up) is not considered valid until it is explicitly set by the user.
Improved: Serial GPS input compatibility improved with multiple devices. See http://wiki.dynonavionics.com/GPS_Configuration_Settings for current compatibility notes.
Improved: DSAB updated to handle all communications between Dynon Avionics products. PC serial ports no longer need to be connected between EFIS and EMS units as previously required. All data and device features, except for setup functions, can now be used from any connected screen.
Improved: When the Rotax 912 engine pre-set configuration is selected via EMS menu > SETUP > GLOBAL > ENGINE TYPE, tach time is not displayed since it is not a meaningful measurement on Rotax engines. Tach time is still available when the Rotax configuration is not selected and engine parameters are configured individually.
Fixed: EMS systems displaying heading information from a connected EFIS now correctly alert if heading is lost.
Fixed: Coolant Temp Sensor Type 4
Fixed: All FlightDEK-D180 units with internal batteries should now turn on solely on the internal battery. Additionally, when the internal battery is installed and charged, removal of master power now correctly results in the unit switching to internal battery power.
Added: Manual set of GPS selected course.
If the GPS serial stream does not supply the selected course sentence, then the COURSE menu can be used to set the course on the HSI page.
Added: Type 4 coolant temperature sensor.
Added: Auto-set of kollsman window.
The current indicated altitude is preserved across a power cycle. If possible, the baro setting is adjusted at power-up so that the new indicated altitude matches the saved value.
Added: Leaning mode fuel flow difference.
After the last cylinder peaks during a leaning operation the difference in fuel flow between the first and last cylinder peaks is displayed. If the fuel flow decreases it is shown as Lean of Peak. If fuel flow increases it is shown as Rich of Peak.
Added: Fuel addition auto detection.
If enabled, at power-up an EMS will detect if fuel has been added above a percentage of the total tank volume in any tank. If detected, the EMS will prompt the pilot to add fuel on the fuel page.
Added: EMS end-user data logging.
The EMS saves many parameters for later retrieval by the Dynon Support Program.
Added: Percent power calculation.
If enabled, percent power is displayed in the color arc of the manifold pressure guage. If a fuel flow sensor is installed, then lean or rich of peak operation is automatically detected. An altitude input from an EFIS is required.
Added: Save settings on power-off.
In addition to the current logic, units will now save their settings when powered off with the front panel button.
Added: Units on airspeed threshold set menu.
The current airspeed units are displayed in the threshold set menus.
Added: Menu restore after alert acknowledge.
If navigating in the menu system and an alarm bar is raised, the current state of the menu is restored after the last alarm is acknowledged or cleared.
Added: Magnetic intensity to magnetic calibration.
As part of the EDC calibration process the pilot must enter the magnetic intensity of the location where the calibration is taking place.
Added: Setting tach and hobbs times tenths.
Tach and Hobbs times may be set in tenths of an hour.
Added: Engine parameter display on EFIS main page.
Added an EFIS info item to display engine RPM and tach if available.
Added: Mechanical style roll indication.
Added another style of roll indication that better mimics a mechanical instrument.
Added: Hooked pitch lines.
Modified the pitch lines to have hooked ends that point toward the horizon.
Added: Fuel flow dial display.
Where possible the digital only fuel flow indicator was swapped with the analog fuel pressure indicator.
Added: Fuel flow info item.
Added: GPS ground track bug.
The old triangle style heading bug on the EFIS heading tape was modified to indicate GPS ground track if available.
Added: New digital airspeed and altitude indicators.
Modified the airspeed and altitude tapes' depiction with scrolling digital numbers aligned with the current indication on the tape. The visible tape range was widened, and the position of tape and corresponding tape numbers was swapped.
Added: Airspeed and turn rate trend indicators.
Added a 6 second indicated airspeed trend bar. Modified the turn rate indicator to indicate a 6 second trend.
Added: Altitude alerter.
Toggling the altitude bug on will activate the altitute alerter function with the bug value as the target altitude. While climbing or descending toward the target altitude a level-off alert sounds when passing through 500' from the target altitude. The target altitude is considered captured when altitude is within 150' of the target. Flying more than 200' away from the target will trigger a short audio alert and alternate the bug in red and yellow as a visual alert. The visual climb or descend alert will clear after recapturing the target altitude or 30 seconds.
Added: Graphical vertical speed indicator.
Added an analog vertical speed indicator. The VSI can be selected for a 1000'/min, 2000'/min or 4000'/min maximum. The indicator bar is scaled to indicate a 6 second altitude trend when in 2000'/min mode, or in 4000'/min mode up to 1000'/min.
Added: Course deviation and glide slope indicators to the EFIS display.
Added a course deviation / cross track deviation and glide slope / vertical deviation indicator to the EFIS display. The color of the bar indicates the currently selected navigation source. The center mark of the CDI functions as the To/From indication with an upward or downward pointing triangle, or blank.
If a conflict between the CDI and the roll scale is detected, then the CDI is removed from the display until the conflict is resolved.
Added: Wind indication on EFIS.
If available, added a depiction of the wind's relative angle and absolute speed on the EFIS.
Added: New altitude and airsped bugs.
Modified the altitude and airspeed bugs' look and feel to match the heading bug on the HSI.
Added: New AOA display.
A new AOA display style was added. This display shows horizantal bars which pull away as AOA increases and turn into downward pointing arrows as AOA approaches stall. A red triangle at the top of the display will flash while AOA audio is active.
Added: User configuration of serial ports.
An HSI Setup menu was added. This menu makes it possible to override the auto detect feature of the local serial port.
Added: AOA audio threshold.
To reduced nuisance AOA audio alerts, a threshold was added under which audio is inhibited. AOA audio is inhibited at power-up. Audio will continue to be inhibited until IAS reaches the threshold (20 kts by default). The AOA bar continues to operate as normal. Once above the threshold audio will be uninhibited and will operate as normal until IAS drops below the threshold. However, if IAS drops below the threshold while audio is active (in a stall), audio will remain active as long as IAS stays alive. This does not fix a bad AOA calibration.
Added: Minimum red line on tach.
Added a minimum red line setting for Rotax engines.
Added: Minimum red line on oil temperature.
For a Rotax engine the oil temperature's arc colors are dynamically set to the fixed values defined by the manufacturer's recommendations.
Added: HSI course setting on EFIS.
The current course setting of the selected source on the HSI is displayed as a V on the heading type. The color indicates the currently selected navigation source.
Improved: Indeterminate attitude alert message.
Modified the ATITUDE INDETERMINATE alert message to be HORIZON RECOVERING...
Improved: Turn coordinator bar visibility.
The turn coordinator was modified to be more visible in all lighting conditions.
Improved: Flight time reset.
The flight time is saved and preserved across a power cycle. It is reset when the oil pressure exceeds 15 PSI for the first time after power-up.
Improved: Leaning mode temperature display.
The temperature drop reading of a cylinder now supports 3 digits so that LOP or ROP temperatures above 99 degrees can be displayed.
Improved: OAT set menu display.
The OAT set menu now display the current temperature units. The menu no longer displays a + sign for positive temperature settings.
Improved: Indicated airspeed active range.
The airspeed indicator now comes alive above 20kts and remains active until going below 15kts.
Improved: Fuel used reset.
Instead of reseting the fuel used at power up, the fuel used is saved and preserved across a power cycle. It is reset when the oil pressure exceeds 15 PSI for the first time after power-up. This means the pilot may record the value at any time prior to the next flight.
Improved: Digital heading display.
Modified the EFIS heading tape to have a digital indicator similar to the HSI.
Improved: Airspeed tape visibility.
Modified the width of the airspeed tape to give more readability to the airspeed thresholds.
Improved: Roll scale tick marks.
Modified the roll indicator scale to have tick marks at 10, 20, 30, 45, 60, and 90 to better mimic a mechanical instrument.
Improved: Heading bug display.
Modified the heading bug on the EFIS heading type to match the bug on the HSI.
Improved: Standard rate turn indicator re-scale.
The turn rate indicator does not rescale when exceeding a standard rate turn.
Improved: Look and feel of the HSI indicators.
Improved: Fuel pressure redline increments.
The fuel pressure color thresholds are now setable in tenths.
Improved: Oil pressure digital display.
Oil pressure display now supports three digits.
Improved: VSI responsiveness.
Responsiveness of VSI indication improved.
Fixed: EFIS not detected alert.
When an EMS loses communication with an EFIS the alert is now displayed properly.
Fixed: Canceling flap calibration process.
It is now possible to cancel flap calibration process before completion without affecting any currently saved calibration.
Fixed: Type 2 ammeter display.
Removed a communications glitch that caused the type 2 ammeter display to go to 99 periodically.
Fixed: Magnetic calibration completion.
Fixed a glitch which would allow the END button to be pressed at the wrong time during a magnetic calibration. This was causing the calibration to be clobbered.
Fixed: Erroneous GPS course display.
Fixed a problemw which would display a course of 360 and a distance to waypoint of 0 when no waypoint was active in the GPS.
Fixed: EMS data output.
Fixed a problem with the EMS serial data output for general purpose inputs.
Fixed: Lowrance GPS integration.
Fixed: EGT span and shock alarm display.
Fixed a problem where EGT span and shock alarms would not trigger the light.
Fixed: Distance to waypoint units.
The distance to waypoint display was using the wrong setting when deteremining units.
Fixed: EFIS display on right 1/3 at boot.
Fixed an initialization problem that caused the wrong palette to be used for a 1/3 EFIS on the right page.
Fixed: Serial output of heading.
Fixed a problem with the serial output calculation for heading which could cause a momentary wrap around condition.
Fixed: Digital display resolution of pressure in bar units.
Any pressure value which displays units with resolutions of 0.1 PSI should also display resolutions of 0.01 bars, when global pressure units are set to bars.
Added: Added HSI overlay to the DG display, supporting serial data from a Garmin SL-30 NAV/COMM or from most GPS units.
Added: DG Display with heading bug and TAS
