Swipe left and right on the main screen to
choose between various displays.
• A small amount of roll install error (+/- 6
degrees) can be corrected during the soft-
ware-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.
MOUNTING YOUR D3 POCKET PANEL

• With the D3 powered on, Press the Menu icon in the upper-left corner, and then go to “Pitch/Roll Adjust”.
• Press the up/down arrows until the displayed pitch matches the current pitch of the aircraft. Note that this
won’t necessarily be “level”, particularly for taildraggers that are being aligned on the ground.
• Press the roll left and roll right arrows until the displayed roll angle indication matches the actual roll angle of
the aircraft. If your aircraft is perfectly level, this means that the horizon should level and the ball centered.
• Touch “Accept” to complete the alignment.
• Wait for a GPS x. When a GPS x is attained, the upper left corner of the display will show GPS signal
strength, and the main display will display ight instruments. GO FLY!
