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.
2. INTRODUCTION Your new D1 Pocket Panel is a portable attitude indicator (artificial horizon) that is designed to be used by ALL pilots. The D1 utilizes the Dynon ARHS technology that has made us the leading supplier of EFIS (Electronic Flight Information Systems) for experimental and light sport aircraft. Unlike other portable devices and apps, the D1 displays actual aircraft attitude, along with additional auxiliary flight instruments that are derived from GPS and other sensors.
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.
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.
Product Tour 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.
Product Tour 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.
Product Tour 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.
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.

5. BEFORE FIRST USE 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).
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.
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.
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 softwarebased alignment process.
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.
Using Your D1 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 Figure 15 - Pitch Adjust Mode Figure 16 - Roll Adjust Mode With the D1 powered on, press the rocker to enter Pitch Adjust Mode.
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.
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.
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.
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.
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.
9. ADDITIONAL MOUNTING OPTIONS Other RAM® Mounts The RAM® suction cup mounting system that is included with your D1 can be adapted and customized with the use of other components. These can be purchased directly from www.rammount.com or from any of RAM’s authorized dealers. The RAM® components that come with the D1 use the B size (1" diameter) ball.
