Using Your D3
5-4 D3 Pilot’s Guide
Mounting Your D3
Mount in the aircraft using one of the provided removable, portable mounts. When mounting the
D3, the following alignment constraints must be met:
• A small amount of roll install error (+/- 6 degrees) can be corrected during the software-based
alignment process.
• A 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 D3 must not be
pointed left or right to face you if it is not directly in front of you. Pointing the D3 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 D3 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.
• Tighten the knob to set the orientation of the cradle. Check that the mount and cradle are
secure.
• Clip the D3 into the cradle. Start with the bottom of the D3. The D3 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 D3 when it is fully clipped in.
• Check that the D3 is secure.
