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.
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.
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.
4. PRODUCT TOUR 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.
Product Tour 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.
Product Tour 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.
Product Tour 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.
Product Tour 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.
Product Tour Figure 11 - Battery Charge Level / External Power Source Icons 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.

Product Tour power down the D2 it must be disconnected from external power sources (both the USB and power cables). Figure 14 - D2 Top Side (left to right): Menu Button, Power Button Right Side PWR: External power via AC Power Adapter or Vehicle Power Adapter. CAUTION: Never use unapproved chargers, never connect more the 5 volts DC and never reverse the polarity of the voltage applied to the power connector or permanent damage may result.
5. BEFORE FIRST USE Before you use your D2 for the first time, please complete the following initial setup and configuration steps: Fully charge the battery (see following section). Check for D2 software updates at www.dynonavionics.com. Choose settings (see following section).
6. USING YOUR D2 Power On/Off Turn the D2 on and off by holding the power button on the top of the device. The D2 will also automatically power on any time an external power source is connected. Charging the Battery BATTERY INFORMATION Only use chargers and power adapters specifically designed for the D2! Connecting other chargers WILL CAUSE DAMAGE to the D2 that will not be repaired under warranty.
Using Your D2 Connect the Power Adapter to the PWR port on the right side of the D2. Leave connected for 4 hours to completely charge from empty. Less time will be needed if the battery is partially charged. The D2 may optionally be powered off while it is charging. To check for a full charge, disconnect the Power Adapter from the D2 and wait 60 seconds for the battery charge indicator to stabilize. Confirm that it is fully charged.
Using Your D2 Mounting Your D2 Mount in the aircraft using one of the provided removable, portable mounts. When mounting the D2, the following alignment constraints must be met: A very small amount of roll install error (+/- 6 degrees) can be corrected during the softwarebased alignment process. A much larger amount of pitch (+/- 30 degrees) can be accommodated via software alignment.
Using Your D2 If you are using the Vehicle Power Adapter to provide continuous power to the D2, 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 D2 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.
Using Your D2 Align the D2 for Flight Figure 16 - Pitch Adjust Mode Figure 17 - Roll Adjust Mode With the D2 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.
Using Your D2 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.
7. PERFORMANCE NOTES Attitude Performance Optimal attitude performance depends on a number of environmental factors: GPS REQUIRED The attitude indication provided by the D2 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 D2 will not display attitude until it has obtained a GPS fix.
Figure 18 - GPS Lost ROTATION RATE LIMIT The D2 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 D2 will continue to display attitude information, but it should be cross-checked against other instruments while in this recovery mode.
Performance Notes Figure 19 - Horizon Recovering After Rate Limit Exceeded AEROBATICS AND NON-STANDARD MANEUVERS The D2’s attitude sensing algorithm is based on fixed wing aircraft flight dynamics. Using the D2 during aerobatics or other maneuvers that are not encountered during normal fixed wing aircraft flight may cause the D2’s attitude indicator to lag the actual horizon or be otherwise incorrect.
8. WIFI OPERATION Using the D2 with WiFi Tablet Applications The D2 attitude information is continually streamed via WiFi to compatible applications. The D2 is compatible with applications supporting the Levil AHRS-G mini ™. No specific user interaction is required to enable this functionality. Technical Details The D2 device has the following WiFi characteristics: TCP/IP address - 169.254.1.1 Supported protocols - TCP/IP and UDP protocols are supported by D2.
9. SOFTWARE UPDATES To update the D2’s software: Check the version of software currently loaded on your D2. 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 D2 software version.
10. ADDITIONAL MOUNTING OPTIONS Other RAM® Mounts The RAM® suction cup mounting system that is included with your D2 can be adapted and customized with the use of other components.
