3 Installation

This section provides information and instructions for installing the Dynon D30.

3.1 Backup Battery Installation

Per shipping regulations, the D30 is shipped without the backup battery installed. Prior to unit
installation, the D30 needs its backup battery installed.

To install the D30's backup battery:

1. On back of unit, loosen captured retaining screw on access plate (see Figure 3), and then
remove access plate.

2. Connect backup battery to unit. Unit and backup battery have mating Molex connectors.

3. Gently insert backup battery and wires into unit.

4. Reposition access plate, and secure with retaining screw.

Figure 3: Backup Battery Access

Page | 3-2

D30 - Installation and Maintenance Manual, Rev A, 7/20/2023

3.2 Unit Installation

The D30 should be installed within the primary maximum field-of-view boundary, as close as
practicable to the equipment that displays Primary Flight Information (PFI). According to AC

23.1311-1C, the primary maximum field-of-view is based on vertical and horizontal visual fields
from the pilot's eye reference point that can be observed with eye movement and minimal head
movement only.

The D30 is designed to mount to the instrument panel in a standard 3-1/8"
diameter instrument hole with little modification. See installation guidelines and
specifications below for more information.

The D30 is designed as near direct-fit replacement for the Dynon EFIS-D10A.

Observe the following guidelines and specifications when installing a D30:

• Unit should be installed so its bezel is level across aircraft's lateral axis.

• Wire harness extends about 3" from the rear of the unit. (This can be reduced if 90°

connector shell is used on the wire harness.)

• A small relief must be cut at the bottom of the 3-1/8" instrument panel hole (see Figure

5).

• If retrofitting an EFIS-D10A with a D30, the holes drilled in the instrument panel for the
EFIS-D10A can be reused for the D30's bracket (see Figure 6).

• Front bezel will extend 0.5" beyond the face of the instrument panel.

• Unit will need to be accessed during service; therefore, provide enough slack in the wire

harness and the pitot and static lines to remove the unit from the instrument panel without
disconnection.

• Avoid placing the unit near sources of heat.

D30 - Installation and Maintenance Manual, Rev A, 7/20/2023

Page | 3-3

Figure 4: Volume Requirements

To mount the D30 to an instrument panel:

1. If needed, use Figure 5 as a guide to mark and drill holes in instrument panel for mount
bracket attachment.

2. Cut small relief at bottom of instrument hole (see Figure 5) to allow clearance for unit's
retaining screw.

3. Deburr cut edges.

4. Feed mount bracket through instrument hole, as shown in Figure 6, and then secure
to instrument panel with provided hardware.

5. Complete pitot and static connection (see Section 3.3) and electrical installation (see
Section 3.4).

6. Insert unit into instrument hole and mount bracket, as shown in Figure 6.

7. Use 3/32" hex wrench to tighten captured retaining screw that secures unit to mount
bracket (see Figure 7). Tighten retaining screw to 3-5 lbs.

3.3 Pitot and Static Connection

The pitot and static ports on the back of the D30 are equipped with 1/8" NPT female fittings.
Installers need to source appropriate flexible hose and AN/MS fittings for connection to existing
pneumatic tubes/hoses.

To plumb the D30 into the pitot and static systems:

1. Find an appropriate place to connect the D30 plumbing to the airplane's existing pitot and
static systems.

2. Measure and cut correct lengths of flexible hoses to connect to the airplane's pitot and
static systems.

3. Install AN/MS fittings into ends of flexible hoses for connection to the airplane's pitot and
static systems.

4. Route flexible hoses and connect them to the airplane's pitot and static systems using
AN/MS fittings.

Ensure there are no low spots in the flexible hoses that could trap
condensation and cause an obstruction.

5. On a bench, remove plugs from the 1/8" NPT fittings on back of unit (see Figure 8). Leave
the AoA pipe fitting capped.

6. Apply appropriate thread sealant to AN/MS fittings and hand-thread them into the 1/8"
NPT fittings on back of unit.

7. When AN/MS fittings are snug, place a wrench on the unit's 1/8" NPT fittings to prevent
them from rotating, and then carefully tighten.

DO NOT overtighten! If the unit's 1/8" NPT fittings rotate during tightening
it may damage its internal components.

8. Connect flexible tubes to the corresponding AN/MS fittings on back of unit.

5.7 Zero-pressure Calibration

This calibration samples pitot and static pressures. This calibration needs to be performed during
initial setup to calibrate airspeed, and as needed if airspeed indicator appears incorrect.

This calibration should be performed in a windless environment to provide the best possible
Indicated Airspeed (IAS) readings at very low airspeeds.

To perform zero pressure calibration:

1. Enter Setup Menu (see Section 3.5.2), and then select Calibration.> Zero Press Cal.

2. Touch Acquire, and then follow on-screen instructions.

5.8 Pitch/Roll Angle Check & Adjustment

This section provides instructions for checking and adjusting the pitch and roll angles on the
attitude indicator to compensate for a tilted instrument panel or unlevel installation. This
calibration should be considered a configuration step that does not need to be performed
routinely.

Pitch angle calibration is not the same as a parallax adjustment on a mechanical attitude
indicator. Additionally, this calibration should not be used to "zero-out" pitch when the airplane
is at an attitude other than level.

Pitch angle can be adjusted 30° to compensate for tilted instrument panels;
roll angle can be adjusted 6°.

To check and adjust the pitch and roll angles:

1. Level airplane according to manufacturer's instructions.

2. View attitude indicator on screen.

• If attitude indicator is aligned with horizon indicator, no further action is required.

• If attitude indicator is not aligned with horizon indicator, complete remaining steps.

3. Enter Setup Menu (see Section 3.5.2), and then select Calibration > Pitch/Roll.

4. Tap up/down arrows to increase or decrease angle as needed to correct pitch on attitude
indicator.

5. Tap left/right arrows to increase or decrease angle as needed to correct roll on the Attitude
indicator.
