4 AV-30-C System Information
4.1 System Description
The uAvionix AV-30-C is a fully digital multi-mode instrument that
mounts in the legacy 3 1/8” round instrument panel. It can be field
configured as either an Attitude Indicator (AI) or a Directional Gyro
(DG) indicator. It is fully self-contained with dual-precision inertial and
pressure sensors and allows for a wide variety of pilot customization.
Figure 1 - AV-30-C Multi Mode AI/DG – Basic Display
When configured as an AI, primary attitude and slip are always
displayed. The un-used portions of the display area can be customized
by the pilot to show a variety of textual and graphical data-overlay
fields. Three pages may be customized by the pilot while a fourth page
presents a fully decluttered view of only attitude and slip.
When configured as a Directional Gyro (DG), direction of flight
information is presented. The flight direction can be configured to be
presented as non-slaved heading or inertially stabilized GPS track
when connected to an external GPS navigator. Multiple display
presentations, including compass rose, GPS HSI, and GPS Arc views
can be selected by the pilot. The un-used portions of the display area
can similarly be configured for a variety of textual data-overlays.
In both operating modes, the pilot may select from multiple visual styles
which are intended to improve visual compatibility with legacy aircraft

instrumentation and preserve the look-and-feel of older aircraft
applications.
A wide variety of supplemental functions, including audio alerting,
derived angle of attack presentation, g-load display, and more are
provided. An internal, rechargeable LiPo battery allows for operation
for a nominal 2 hours in the event of aircraft power loss and 30 minutes
minimum under all temperature conditions.

5 Certification
This installation manual provides mechanical and electrical information
necessary to install the AV-30-C. The content of this manual assumes
use by competent and qualified personnel using standard maintenance
procedures in accordance with Title 14 of the Code of Federal
Regulation (CFR) and other related accepted procedures.
The certification basis for the AV-30-C is 14 CFR Part 23, Amendment
23-61. Installation is approved as a Level A system and is robust to
High Intensity Radiated Field (HIRF) and lightning levels applicable for
both metallic and non-metallic aircraft.
The AV-30-C is approved for primary Attitude, Slip and
Direction of Flight.
All other functionality is supplemental in nature and may not satisfy
regulatory requirements for required instrumentation.
The installer must ensure that all installation limitations as
defined in this document are observed.
The internal battery capacity has been tested and verified to provide 30
minutes of operational capacity (with reserve), and meets the
requirements defined in CFR 23.1311(a)(5) and 23.1353(h), allowing
independent operation from the primary electrical power system.
See Section 8.3 Internal Battery Operation for additional battery
operational characteristics.
For aircraft capable of acrobatic flight, the AoA indication may
become unreliable for operation in inverted flight and maneuvers
exceeding ±8 G.

UAV-1003947-001, AV-30-C, Installation Manual 12 Revision C
5.1 Mechanical Instrument Replacement
Approval is granted to replace legacy mechanical instrumentation as
follows:
 Installation of the AV-30-C (Dedicated AI mode) as the primary
source for attitude and slip. Installation replaces the existing
stand-alone vacuum or electrically powered attitude indicator.
 Installation of the AV-30-C (Dedicated DG mode) as the primary
source for direction-of-flight. Installation replaces the existing
stand-alone vacuum or electrically powered non-slaved directional
gyro indicator.
Note that when installed as a DG, a reversionary AI is available for
display. This functionality is supplemental only and does not satisfy
requirements for a backup or standby attitude, turn and slip, or turn
coordinator.
5.2 Non-Required Instrument Addition
Approval is granted to install the AV-30-C as a non-required
instrument, augmenting existing required instrumentation. In this
configuration, the AV-30-C must not replace an existing required
instrument.
5.3 Vacuum System Removal
The aircraft’s vacuum system typically may be removed under a field
approval process (FAA form 337) if no other systems or equipment
requires it. The AV-30-C installation approval does not address this
alteration.

The following figure shows a typical “six-pack” and one possible
arrangement of instrument locations:
AI
DG AI/DG
Figure 2 – Mechanical Gauge Replacement
Note that the physical arrangement in many aircraft varies from the
traditional “T” configuration shown above. The AI/DG locations are
examples of installation locations as a non-required instrument.
The existing mechanically based altimeter and airspeed
indicator must remain in their factory locations for this
installation configuration.
Installation as a pilot configurable AI/DG may not replace a
primary instrument.
The replaced instruments may NOT be part of an autopilot or primary
navigational display, such as an integrated autopilot system, autopilot
heading bug source, attitude source, CDI, HSI or flight director display.
Reference CFR 23.1321 Arrangement and Visibility for
additional FAA guidance on instrument installation location.

UAV-1003947-001, AV-30-C, Installation Manual 16 Revision C
7.2 Operating Mode Configuration
The AV-30-C operating mode is configured during installation and can
be set as follows:
 Unit locked as a dedicated Attitude Indicator (AI Mode)
 Unit locked as a dedicated Direction Indicator (DG Mode)
 Unit can be toggled between AI and DG mode by the pilot
Installations where dedicated functionality is required must have the
associated setting configured in the setup procedures. This setting is
mandatory and non-pilot accessible.
If the functionality is not locked, pressing and holding the rotary knob
will toggle between AI and DG mode. This mode is only applicable for
installation as a non-required instrument.
An AV-30-C that replaces the Attitude Indicator must have the
operating mode locked as an AI.
An AV-30-C that replaces that Directional Gyro must have the
operating mode locked as a DG.
An AV-30-C installed as a non-required indicator may be
configured in any operating mode based on pilot preference.
Replaced instruments may NOT be part of an autopilot system such as
the rate-of-turn source for an autopilot or display of flight director
information from an autopilot.

UAV-1003947-001, AV-30-C, Installation Manual 19 Revision C
8.2.1 Power Input (Required)
Power input is required and connects to the aircraft’s power bus.
Input range is compatible with both 12V and 24V aircraft. Internally,
this power is diode OR’ed with the internal battery via a processor-
controlled switch. This architecture allows the unit to continue
operation if external power fluctuates or is completely lost.
Each AV-30-C must have a dedicated, properly labeled, pilot
resettable circuit breaker as part of the installation. Power for the
unit may be supplied from either the avionics bus or the main battery
master relay.
8.2.2 Pitot and Static Interfaces (Required/Optional)
In addition to directly displayable data such as airspeed and altitude,
pitot and static inputs are utilized within the probeless Angle of
Attack algorithm and provide the underlying source for various air-
data type data overlays (TAS & DALT).
When installed as a DG, pitot and static connections are not required
unless TAS and DALT are desirable (also requires a dedicated OAT
probe). See the detailed wiring diagram for more information.
8.2.3 Outside Air Temp Input (Optional)
The optional outside air temperature interface requires a dedicated
external analog probe. This port connection is compatible with the
Davtron P/N C307PS (not supplied).
This is a differential two-wire current source based on the Analog
Devices AD590KH component and supplies a current that
corresponds to the ambient temperature.
If two displays are connected to the same probe, the current
will be split between the two and incorrect readings will be
shown by both.
The sensor reading must be trimmed during the installation process
to compensate for probe-to-probe variations.

UAV-1003947-001, AV-30-C, Installation Manual 20 Revision C
The OAT probe is automatically detected by the system, and when
detected, allows temperature related parameters to be selected for
display by the pilot.
If the OAT probe is not detected, display of these parameters will
automatically be inhibited.
8.2.4 Audio Output (Optional)
The optional audio panel connection is a low-voltage analog output
that is designed to connect directly to an audio panel (typically a
non-switched input). High power outputs capable of directly driving a
cockpit speaker are not provided.
When installed as a DG, no audio alerting is supported, and this
output should remain disconnected.
In non-metallic, IFR capable aircraft, this connection MUST
remain disconnected due to lightning strike limitations.
8.2.5 GPS Interface (Optional)
The GPS interface is an optional RS-232 serial input that is
compatible with the industry standard “Moving Map” output provided
by most panel mounted GPS units, and NMEA serial interfaces
provided by most hand-held GPS units.
This is a text/binary protocol output by the GPS navigator that
contains situational awareness information such as ground speed,
track, distance to destination, cross track, etc, and is typically utilized
by remote mapping/display products to provide additional pilot
awareness.
This output does not provide IFR compliant lateral or vertical
guidance, therefore all deviation related data presented is for VFR
operations only.
The AV-30-C does no computations or operations on the data
obtained from the GPS navigator, and simply displays the received
data in a textual or graphical format as configured by the pilot.
