1. SAFETY AND LICENSING INFORMATION
Important Safety Information
Your Dynon Avionics D2 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 D2 battery with Dynon Avionics chargers that are specifically intended for use with the
D2. Using any other charger to charge the D2 battery could cause the battery to explode or cause
damage to the D2.
Do not expose the D2’s Li-Ion battery to fire or otherwise expose them to excessive heat.
Please dispose of non-functional batteries in a responsible manner. The battery for your D2 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 D2.
This device is not waterproof. It is not designed to be used in wet conditions.
Do not operate this device below -15˚C (5˚F) or above 60˚C (140˚F). Prolonged sunlight exposure may
result in excessively high temperatures.
Do not drop this device, especially onto hard surfaces or from great height.
Do not attempt to modify or repair this device. There are no user-serviceable parts inside. Doing so will
void the warranty.

2. INTRODUCTION
Your new D2 Pocket Panel is a portable attitude indicator (artificial horizon) that is designed to be
used by pilots of certified, light sport and experimental aircraft. The self-contained design of the
D2, not requiring permanent installation in an aircraft, makes it an ideal backup instrument for
certified aircraft.
Features
Proven Dynon MEMS-based (MicroElectroMechanical Systems) attitude sensors
Accurate pitch and roll: A true artificial horizon
Backup attitude instrumentation for all certified, experimental and light sport aircraft
WiFi interface for remote attitude display on Tablet devices
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), 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

3. PRODUCT LIMITATIONS
The D2 Pocket Panel is a portable device that aids situational awareness. As the D2 does not have
TSO authorization from the FAA or other regulatory body, it is not suitable for permanent
installation in type certificated aircraft.
The D2’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 D2’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.

On-Screen Elements
The D2 is primarily a portable backup attitude indicator but also has a second screen that displays
the aircraft load factor (G meter). Switch between the two displays with a press and release of
the menu button.
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.
Like a mechanical attitude
indicator, the artificial horizon
depicted on the D2 screen
displays both the pitch and roll
of the aircraft.
Figure 1- Full D2 Display with Attitude
Pitch angle is read by noting the position of the indexed pitch ladder against the centered yellow-
outlined 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.

4-2 D2 Pilot’s Guide
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.
Figure 3 - Roll
GPS Ground Speed is the aircraft’s speed over the ground in knots, miles per hour, or kilometers
per hour as determined by the D2’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

Product Tour
D2 Pilot’s Guide 4-3
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 D2’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 D2’s GPS. It is displayed both numerically and as a graphical arc. GPS ground track is oriented
to magnetic north - not true north - similar to your magnetic compass. However, due to winds,
GPS ground track will usually not exactly match the heading provided by your aircraft’s magnetic
heading compass/instrument. Therefore, the GPS Ground Track indication should not be used as a
replacement for a magnetic heading instrument.

Product Tour
4-4 D2 Pilot’s Guide
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 D2’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.
Figure 7 - GPS Vertical Speed

D2 Pilot’s Guide 4-5
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
below depicts a half-standard rate turn to the left.
Figure 9 - Turn Rate
GPS Signal Strength is depicted in the upper left corner of the display. “Ext” is displayed to the
right of the GPS Signal Strength indication when the external GPS antenna is connected.
Figure 10 - GPS Signal Strength
Battery Charge Level is depicted in the upper right corner of the display. This indication turns into
an AC plug icon when connected to an external power source.

Load Factor (G Meter) is determined by accelerometers and displayed as an analog-style gauge.
Configurable settings are provided for the color coded (red/yellow) ranges for both positive and
negative G loads.
The D2 Load Factor (G meter)
display has two selectable ranges
to meet the needs of Normal
Category aircraft and Aerobatic
Category aircraft.
The caution (yellow) and warning
(red) ranges are selectable from
the settings menu in 0.1 G steps.
The yellow range will always end
at the start of the red range. The
default values are shown.
Maximum positive and negative
G loads are displayed and may be
reset by pressing in on the jog
wheel on the right side.
