1. SAFETY AND LICENSING INFORMATION
Important Safety Information
Your Dynon Avionics D1 Pocket Panel contains a Li-Ion battery. Li-Ion batteries are safe when used as
directed, but can also be hazardous if they are not used in accordance with their instructions.
Only charge the D1 battery with Dynon Avionics chargers that are specifically intended for use with the
D1. Using any other charger to charge the D1 battery could cause the battery to explode or cause
damage to the D1.
Do not expose the D1’s Li-Ion battery to fire or otherwise expose them to excessive heat.
The Vehicle Power Adapter must not be modified – it converts aircraft voltage to 5V that the D1 can
use. Cutting off the Vehicle Power Adapter’s base to connect it directly to ships power WILL DESTROY
your D1.
Please dispose of non-functional batteries in a responsible manner. The battery for your D1 is very
similar to mobile phone batteries and can likely be recycled wherever mobile phone battery recycling is
available. For a list of recycling locations in your area (USA only), call 1-800-8-BATTERY or see the Call 2
Recycle website at www.rbrc.org.
This device is designed to operate safely only with Dynon-supplied chargers that are specifically made
for the D1.

Internal high capacity Li-Ion battery and GPS for hours of portable use
Versatile portable mounts: RAM suction mount and 3 ⅛” panel hole “pinch” mount both
included
GPS ground speed and ground track (direction)
GPS altitude and vertical speed
Turn rate
Slip/skid ball
Dimmable display for night flight
Truly pocket sized - approximately 3½”Width x 3¼” Height x 1” Depth
D1 Pilot’s User Guide 2-1
3. INTENDED USE
The D1 Pocket Panel is a portable device that aids situational awareness. As the D1 does not have
TSO authorization from the FAA or other regulatory body, is not suitable for permanent
installation in type certificated aircraft.
The D1’s Ground Speed, Altitude, Vertical Speed, and Ground Track (direction) instruments are
GPS-derived. Their indications WILL BE DIFFERENT from the airspeed, altimeter, VSI, and heading
instruments in your aircraft panel. The D1’s GPS-based indications should not be considered
replacements for any of these primary aircraft instruments. Details about each of these
differences are described in the Product Tour section of this guide.
D1 Pilot’s User Guide 3-1
4. PRODUCT TOUR
On-Screen Elements
Aircraft Attitude is determined by combining information from internal solid state rotation rate
sensors (gyros) and accelerometers. GPS information is additionally used to ensure the quality of
the displayed attitude indication. When properly aligned to the aircraft, the D1’s attitude will
perform as well or better than a conventional mechanical gyro-based attitude indicator.
Figure 1- Full D1 Display with Attitude
D1 Pilot’s User Guide 4-1

Pitch angle is read by noting the position of the indexed pitch ladder against the centered yellowoutlined black square. There are extended pitch cues, also in yellow-outlined black to the left and
right of the primary aircraft pitch indication. In the example above, the aircraft is pitched up
approximately 1 degree.
Figure 2 - Pitch
Roll angle is indicated by the position of the yellow triangular roll pointer with respect to the arc
above it. There are tick marks on the roll arc at 10, 20, and 30 and 60 degrees of bank, and
triangles at 45 degrees of bank. In the example above, the aircraft is banked approximately 2
degrees to the left.

GPS Ground Speed is the aircraft’s speed over the ground in knots, miles per hour, or kilometers
per hour as determined by the D1’s GPS. GPS ground speed will not match your pitot/static
airspeed instruments due to wind. Since GPS ground speed does not take into account the
dynamic pressure of the air acting on the aircraft, it does not provide the information necessary to
determine if the aircraft is close to stalling. It should not be used as a reference when landing the
aircraft.
Figure 4 - GPS Ground Speed
GPS Altitude is the aircraft’s altitude in either feet or meters as determined by the D1’s GPS. GPS
altitude will not always match your aircraft’s static system-based barometric altimeter, and should
not be used as a replacement for one.
Figure 5 - GPS Altitude
GPS Ground Track is the direction that the aircraft is moving over the ground as determined by
the D1’s GPS. It is displayed both numerically and as a graphical arc. GPS ground track is adjusted
for estimated magnetic variation rather than being aligned to true north. However, GPS ground

track will not always match the heading information provided by your aircraft’s magnetic heading
instrument or compass, and should not be used as a replacement for one.
Figure 6 - GPS Ground Track
GPS Vertical Speed depicts the rate of climb or descent of the aircraft in thousands of feet per
minute or meters per second as determined by the D1’s GPS. GPS vertical speed will not always
match the indication provided by your aircraft’s static-based vertical speed indicator, and should
not be used as a replacement for one. In the example above, the GPS Vertical Speed is indicating a
400 feet per minute ascent rate.

The Slip/Skid Ball provides a visual representation of lateral acceleration. When the ball is within
the two vertical lines, the aircraft is in coordinated flight. The slip/skid ball operates
independently of GPS reception.
Figure 8 - Slip / Skid Ball
Turn Rate is displayed as a curved magenta bar along the top outside curve of the GPS ground
track arc. The bar grows in the direction that the aircraft is currently turning. The inner white
markings on the turn rate indicator indicate a half standard-rate turn of 1.5 degree per second.
The outer white markings indicate a standard rate turn of 3 degrees per second. The example
above depicts a half-standard rate turn to the left.

Before you use your D1 for the first time, please complete the following initial setup and
configuration steps:
Fully charge the battery (see following section).
Check for D1 software updates at www.dynonavionics.com.
Choose settings (see following section).
D1 Pilot’s User Guide 5-1
6. USING YOUR D1
Power On/Off
Turn the D1 on and off by holding the power button on the top of the device. The D1 will also
automatically power on any time a power is applied to the PWR port on the right side of the unit.
Charging the Battery
BATTERY INFORMATION
Only use chargers and power adapters specifically designed for the D1! Connecting other chargers WILL
CAUSE DAMAGE to the D1 that will not be repaired under warranty.
The D1 is powered by an internal Li-Ion battery that provides at least 4 hours of use from full
charge when not connected to an external power source. The amount of time that the battery will
operate the D1 from a full charge will vary with temperature, GPS visibility, use of the external
GPS antenna, and the brightness setting.
CHARGE USING THE AC POWER ADAPTER OR VEHICLE POWER ADAPTER
Only use chargers and power adapters specifically designed for the D1! Connecting other chargers WILL
CAUSE DAMAGE to the D1 that will not be repaired under warranty.
The Vehicle Power Adapter must not be modified – it converts aircraft voltage to 5V that the D1 can
use. Cutting off the Vehicle Power Adapter’s base to connect it directly to ships power WILL DESTROY
your D1.
D1 Pilot’s User Guide 6-1
Using Your D1
Plug the AC Power Adapter into a standard wall plug, or the Vehicle Power Adapter into a
vehicle DC socket. The Vehicle Power Adapter is designed to work in cars, 14V aircraft, and 28V
aircraft.
Connect the Power Adapter to the PWR port on the right side of the D1.
Leave connected for 4 hours to completely charge from empty. Less time will be needed if the
battery is partially charged. The D1 may optionally be powered off while it is charging.
To check for a full charge, disconnect the Power Adapter from the D1 and wait 60 seconds for
the battery charge indicator to stabilize. Confirm that it is fully charged.
CHARGE VIA USB
The D1 may also be charged via the mini-USB port on its left side. Any standard mini-USB power
adapter that outputs standard USB power (5V DC) may be used. Charging via mini-USB will take
considerably longer than when using an AC or Vehicle Power Adapter. The exact charge time will
vary with the capability of the mini-USB power adapter used. Additionally, note that attaching
USB power to a powered of D1 will not power it on like attaching power to the PWR port does.
If you use a computer as your USB power source, the D1’s file system can be seen on your computer.
Changing any of the D1’s files will likely cause it to become unstable or inoperable. Additionally, do not
use the D1’s file system as a storage device.
ADJUSTING SETTINGS
You can adjust settings such as ground speed units (KTS / MPH / KPH), altitude units (feet /
meters), whether or not the D1 turns off when external power is removed/lost, and whether the
D1 automatically shuts down after 15 minutes of inactivity (while also not moving). To adjust
these settings on your D1:
Press and hold the Menu Button to enter the Settings Menu.
6-2 D1 User Guide
Using Your D1
Press the Rocker to advance through different settings.
Move the rocker up and down to adjust a selected setting.
When you are finished, press the Menu Button again to exit the Settings Menu.
Mounting Your D1
Mount in the aircraft using one of the provided removable, portable mounts. When mounting the
D1, the following alignment constraints must be met:
A very small amount of roll install error (+/- 6 degrees) can be corrected during the software-
based alignment process.
A much larger amount of pitch (+/- 30 degrees) can be accommodated via software alignment.
For proper yaw alignment, the unit must be aligned so that the surface of the display is parallel
with the lateral axis (wingtip to wingtip) of the aircraft. In other words, the D1 must not be
pointed left or right to face you if it is not directly in front of you. Pointing the D1 left or right
will cause the attitude, turn rate, and slip/skid ball indications to be degraded.
RAM Suction Cup Mount
Attach the square RAM mount plate to the plastic D1 cradle using the included hardware.
Connect the above assembly to the suction base via the included short connecting arm.
Mount the suction cup to a surface that is capable of supporting the weight of the assembly. A
canopy or windscreen that has a minimal amount of curvature is ideal.
Loosen the knob on the arm to align the cradle so that it meets the roll, pitch and yaw
mounting criteria above.
D1 User Guide 6-3
Using Your D1
Tighten the knob to set the orientation of the cradle. Check that the mount and cradle are
secure.
Clip the D1 into the cradle. Start with the bottom of the D1. The D1 will positively snap into the
cradle as you press the top side in. The cradle’s wings will sit flush along the top and bottom
faces of the D1 when it is fully clipped in.
Check that the D1 is secure.
If you are using the Vehicle Power Adapter to provide continuous power to the D1, route the
wire through the channel along the bottom right of the cradle.
Pinch Mount
The pinch mount is designed to allow portable use of the D1 in an empty standard 3 ⅛” aircraft
instrument hole.
Retract the mount’s retention arms by pinching together the finger holes on the front of the
mount.
With the retention arms pinched together, place the pinch mount flush against the panel over
the instrument hole.
Let go to wedge the arms in the instrument hole.
Ensure that the mount meets the roll, pitch and yaw mounting criteria above.
Check that the mount and cradle are secure.
Clip the D1 into the cradle. Start with the bottom of the D1. The D1 will positively snap into the
cradle as you press the top side in. The cradle’s wings will sit flush along the top and bottom
faces of the D1 when it is fully clipped in.
Check that the D1 is secure.

Using Your D1
Figure 15 - Pitch Adjust Mode
Figure 16 - Roll Adjust Mode
If you are using the Vehicle Power Adapter to provide continuous power to the D1, route the
wire through the channel along the bottom right of the cradle.
When using the pinch mount, Dynon highly recommends using the optional external GPS
antenna as the D1’s view of the sky is likely to be obscured by aircraft structure.
Align the D1 for Flight
With the D1 powered on, press the rocker to enter Pitch Adjust Mode. Move the rocker up or
down until the displayed pitch matches the pitch of the aircraft.
Depress the rocker again to adjust roll. Move the rocker up or down until the displayed roll
angle indication matches the actual roll angle of the aircraft. If your aircraft is perfectly level,
this means that that you want the horizon level and the ball centered.
The roll and pitch adjust modes will automatically exit after a few seconds of inactivity.
Wait for a GPS fix. When a GPS fix is attained, the upper left corner of the display will show GPS
signal strength, and the main display will display flight instruments.
D1 User Guide 6-5
Using Your D1
If GPS lock takes too long to achieve, or you have the D1 installed in a place where it’s internal
GPS antenna is unlikely to get a lock (such as in the panel), plug in the external GPS antenna
and ensure it has a clear view of the sky. The top of the panel glare shield is usually a good
choice for GPS antenna placement.
Go Fly! ™
You may find that you need to re-adjust the roll and pitch a bit more in flight. Simply press the
Rocker to re-adjust pitch and roll.
Adjusting Brightness for Night Flight
When not adjusting pitch, roll, or any other settings, moving the Rocker up and down will increase
and decrease the backlight of the display.
Protecting Your D1
Many cases that are designed for 4.3” and 5” automotive GPS units can work well for protecting
your D1 while in your flight bag. A variety of inexpensive options are available from Amazon.
Additionally, the rugged Pelican 1020 Micro Case is known to hold the D1 securely with no
modification required.
6-6 D1 User Guide
7. PERFORMANCE NOTES
Attitude Performance
Optimal attitude performance depends on a number of environmental factors:
GPS REQUIRED
The attitude indication provided by the D1 is primarily created by combining information from
solid state MEMS-type accelerometers and rotation rate sensors, and supplemented by GPS
ground speed. In order to display as reliable an indication as possible, a GPS fix is required. The D1
will not display attitude until it has obtained a GPS fix. Once a GPS fix is obtained, it is important
that the GPS fix be maintained by either mounting the D1 in a position that affords it a good view
of the sky, or, if that is not possible (such as when using the pinch mount to panel-mount the D1),
using the included external GPS antenna.
Loss of GPS
Lapses in GPS coverage may degrade attitude accuracy, depending on the length of the outage.
During short lapses, the message GPS LOST: CROSS-CHECK HORIZON will appear at the bottom of
the display to indicate that the D1’s attitude indication may be degraded and should be
interpreted cautiously. Additionally, the indications that rely solely on GPS will be replaced with
red Xs. If the GPS signal is lost for a more substantial amount of time, the D1’s attitude will also be
replaced by a red X to indicate the D1’s inability to determine attitude.
D1 Pilot’s User Guide 7-1
Performance Notes
Figure 17 - GPS Lost
ROTATION RATE LIMIT
The D1 will operate normally with rotational rates of up to 150 degree per second around any
axis. If a rate of 150 degrees per second is exceeded, HORIZON RECOVERING will be displayed
along the bottom of the display. The D1 will continue to display attitude information, but it should
be cross-checked against other instruments while in this recovery mode. After a few seconds of
straight and level flight, the HORIZON RECOVERING message will automatically disappear when
the D1 is confident that it is showing the correct attitude.
7-2 D1 User Guide
Performance Notes
Figure 18 - Horizon Recovering After Rate Limit Exceeded
AEROBATICS AND NON-STANDARD MANEUVERS
The D1’s attitude sensing algorithm is based on fixed wing aircraft flight dynamics. Using the D1
during aerobatics or other maneuvers that are not encountered during normal fixed wing aircraft
flight may cause the D1’s attitude indicator to lag the actual horizon or be otherwise incorrect.
This will especially be true if the maneuvers being performed exceed 150 degrees per second as
described above. However, once straight and level flight is resumed for a short period, the D1 will
automatically recover and display the correct attitude. Additionally, no aerobatic flight maneuver
will cause any permanent damage to the D1’s attitude sensing ability.
D1 User Guide 7-3
8. SOFTWARE UPDATES
To update the D1’s software:
Check the version of software currently loaded on your D1. The software version is displayed
for a few seconds at the bottom of the screen immediately after you press the rocker to
acknowledge the safety message upon power on. It is also displayed in the Settings Menu.
Check www.dynonavionics.com for the latest D1 software version.
If the version number on the Dynon website is higher than the one your D1 currently has,
download the current version from the Dynon website.
Copy the downloaded .d1s file to an SD card (not included). Put the file on a blank SD card.
Firmware updates for the D1 are only a few megabytes, so any size SD card is suitable for this
operation.
Fully insert the SD card into the D1 until it clicks into place, with the SD Card label facing the
back of the D1. You may need to use a small, thin tool – a US quarter works well – to fully
engage and click the SD card in the slot.
Power on the D1.
The D1 will automatically update and display further instructions and status.
Remove the SD card once the update is complete. Restart the D1 using the Power Button.
Confirm that the software is up to date by confirming that the version number shown at power
on matches the version you downloaded from the Dynon website.

12. REQUESTING SUPPORT / REPAIR
Before contacting Dynon Avionics Technical Support, please consult the Troubleshooting section
of this guide for solutions to common issues.
In some circumstances, performing a reset may fix some issues. To reset the D1:
Plug the unit into external power.
Insert a paperclip or other similar tool in the small round RESET button hole on the left side of
the unit. Push until you feel the reset button “click”.
The D1 should now power on.
When contacting Dynon Technical Support, have your D1 at hand. If possible, have the AC Adapter
(charger) also at hand to provide power if there is a battery issue.
