1. SAFETY INFORMATION
Important Safety Information
Your Dynon Avionics D3 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.
Do not expose the D3’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 D3 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 charge via included USB-C chargers. Some third-party USB-C chargers may not
charge the D3.
This device is not waterproof. It is not designed to be used in wet conditions.
Do not operate this device below -20˚C (-4˚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.

3. PRODUCT LIMITATIONS
The D3 Pocket Panel is a portable device that aids situational awareness. As the D3 does not have
TSO authorization from the FAA or other regulatory body, it can not be used to replace any
required flight instruments in type certificated aircraft.
The D3’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 D3’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 D3 is primarily a portable backup attitude indicator but also has a variety of other useful
information to improve situational awareness.
Aircraft Attitude is determined by combining information from internal solid-state rotation rate
sensors (gyros) and accelerometers. GPS-based ground speed is additionally used to ensure the
quality of the displayed attitude
indication. Like a mechanical
attitude indicator, the artificial
horizon depicted on the D3
screen displays both the pitch
and roll of the aircraft. The D3’s
attitude depiction is not GPS-
based, but a GPS fix is required
for the attitude to work
properly.

Pitch angle is read by noting the position of the indexed pitch ladder against the centered white-
outlined black square. There are extended pitch cues, also in white-outlined black to the left and
right of the primary aircraft pitch indication. In the example below, the aircraft is level in pitch.
Figure 4 - 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, 45, and 60 degrees of bank. The
triangle pointers are a dynamic estimate of the roll angle that would be required to achieve a
standard rate turn at the current speed. In the example below, the aircraft is banked
approximately 1 degrees to the left. It would take approximately 22 degrees of bank to achieve a
standard rate turn.

D3 Pilot’s Guide 4-5
GPS Ground Speed is the aircraft’s speed over the ground in knots, miles per hour, or kilometers
per hour as determined by the D3’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 6 - GPS Ground Speed
GPS Altitude is the aircraft’s altitude in either feet or meters as determined by the D3’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 7 - GPS Altitude

GPS Ground Track is the direction that the aircraft is moving over the ground as determined by
the D3’s GPS. It is displayed both numerically and as a graphical arc when using the Classic style. In
TRK Overlaid mode, it is depicted as a circular compass-style indicator overlaid on the attitude
indicator, with the numerical track above the roll scale. 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 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.
