6 AV-30-C System Information
This document provides instructions on the installation requirements for the
uAvionix AV-30-C multi-mode instrument.
6.1 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 unused 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 a 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
unused portions of the display area can similarly be configured for a variety
of textual data-overlays.

UAV-1003947-001, AV-30-C, Installation Manual 10
Rev E
In all 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 battery allows for operation for a nominal 2 hours in
the event of aircraft power loss in flight and 30 minutes minimum under all
temperature conditions.
See AV-30-C Pilots Guide UAV-1003946-001 for additional details.

7 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 §10.3 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.

Rev E
7.1 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.
7.2 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.
7.3 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.

8 Installation Limitations
The following section provides the FAA approved installation limitations.
8.1 Installation Approval Limitations
This article meets the minimum performance and quality control standards
required by an Approved Model List - Supplemental Type Certificate (AML-
STC) and when installed on aircraft approved on the AML can be
approved for return to service after installation.
If installation for an aircraft that is not listed on the AML, separate approval
must be obtained. The following installation limitations apply:
•Installation is restricted to CFR Part 23, Class I and II, single engine aircraft only
(gross take-off weight of no more than 6000 lbs, 6 seats or less, including
pilot/copilot).
•Installation is restricted to aircraft with a 25,000-foot maximum (or less) ceiling
limitation.
•Installation is restricted to aircraft with equal to or less than 300 knot Vne
airspeed.
•Installation may not be performed as part of an integrated autopilot system
including heading bug interface, attitude source or flight director display.
•Installation may not be performed as a replacement of a Horizontal Situational
Awareness Indicator (HSI).
•In installations where the primary attitude indicator is being replaced, the
existing airspeed and altimeter must remain in their factory locations.
•An electrical load analysis must be performed in association with the
installation.
•Connection to the Audio interface is not allowed for IFR approved non-metallic
aircraft due to indirect lightning protection limitations.
•A Wet compass must be installed in the aircraft.

9 Installation Locations & Operating Modes
9.1 Installation Locations
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
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 18
Rev E
9.2 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 unlocked; 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.
