4 AV-30-E System Information
4.1 System Description
The uAvionix AV-30-E 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-E 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 unused 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

UAV-1004233-001, AV-30-E Pilot’s Guide 9 Revision A
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.

Figure 3 – AV-30-E Aircraft Systems Interfaces – DG Mode
When installed as a DG, no audio outputs are supported, and air data
related parameters are only available when the optional OAT probe is
equipped.
5.2 Power Input (Required)
Power input is required in both AI and DG configurations and each
unit has a dedicated circuit breaker. The power input is internally
diode OR’ed with the unit’s internal battery via a processor-controlled
switch. This architecture allows the unit to continue operation if
external power fluctuates or is completely lost.
When external power is supplied to the AV-30-E, there is no
mechanism to turn the unit off. When operating on battery, the unit
may be forced off with a user interface action. Reference Section 10 -
Internal Battery Operation for more information.

UAV-1004233-001, AV-30-E Pilot’s Guide 13 Revision A
5.3 Pitot and Static Interfaces
Pitot and static connections are required for the AI, and optional for
DG installations.
Airspeed, altitude, derived angle of attack, TAS and DALT all require
pitot static connections as they are based on either altitude or
airspeed measured from those connections.
When installed as a DG, the pitot static connections are required
when the OAT probe is installed.TAS and DALT are the only air-data
related parameters that can be displayed when in DG mode.
5.4 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-E 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.
5.5 OAT Probe (Optional)
The optional OAT probe interface is compatible with the industry
standard “Davtron” probe which is mounted external to the aircraft.
OAT data is available as a textual data overlay and is used to
compute temperature dependent data such as TAS and DALT.Each
AV-30-E requires a dedicated probe and a single OAT probe cannot
be shared between multiple units.

UAV-1004233-001, AV-30-E Pilot’s Guide 14 Revision A
The OAT probe is automatically detected by the system, and when
present, allows temperature related parameters to be selected for
display. If the OAT probe is not detected, display of these parameters
is inhibited.
5.6 Audio Output (Optional)
The optional audio output provides audio alerts for the various alerting
conditions. This output is typically connected to the aircraft’s non-
switched audio input on the audio panel. Audio alerting thresholds
and enable / disable of the alerts are configured by the pilot in the
Setup Menu.
Audio alerting is only supported when configured as an AI.
5.7 tailBeaconX Control (Optional)
The AV-30-E has the option of being the transponder control interface
for an installed tailBeaconX allowing the user to change the Mode and
Squawk input to the tailBeaconX.

There are three independently customizable pages which are
selected round-robin fashion by sequentially pressing the Page
Selection button (shown as page 1 of 3 in the figures above).
A fourth, fully decluttered page allows all supplemental information to
be hidden, leaving just attitude and slip displayed.

UAV-1004233-001, AV-30-E Pilot’s Guide 17 Revision A
6.2.2 AI Mode – Attitude / Slip
The basic display of attitude and slip consists of a traditional attitude
indicator display and slip-ball as follows:
Figure 8 - AI Mode, Attitude Indicator
On initial startup the red ALIGN flag will flash,
indicating that the attitude is still stabilizing.
The aircraft should be held as motionless as
possible during the aligning process.
When the ALIGN flag is displayed, the presented attitude
may be incorrect.
6.2.3 AI Mode – Airspeed Indicator
Indicated airspeed can be configured for display on the left side of
the screen. The configured units (KTS or MPH) is displayed below
the speed value.

UAV-1004233-001, AV-30-E Pilot’s Guide 18 Revision A
Figure 9 – AI Mode, IAS Indicator
The inner arc is a color-coded v-Speed band that rotates to show the
configured v-Speed limits against the non-moving white tic-mark.
The lower arc portion below Vs1 provides a red colored slow-speed
band that is only displayed when the airspeed has been above Vs1
for a given flight.
The color of the indicated airspeed numerals will turn yellow when
operating in the yellow speed arc, red when operating in a red speed
arc, but are otherwise white.

On initial startup, the airspeed field will be dashed while

Airspeed display units and v-Speed limits are configured during
installation and are not pilot accessible.
6.2.4 AI Mode – Flight Direction Indicator
The upper portion of the AI can be configured to display direction of
flight in the form of either non-slaved DG (non-slaved heading) or
GPS track.

UAV-1004233-001, AV-30-E Pilot’s Guide 19 Revision A
Both modes support a magenta heading bug and the GPS track
mode supports a green bearing-to indicator. The heading bug is not
interfaced to the autopilot and is for reference only.
If no GPS is detected, an amber “NO GPS” will be displayed in lieu
of the track.
If either the heading bug or the bearing to bug are off the left or right
sides of the screen, a colored arrow will show the shortest-turn
direction to the corresponding bug.
Figure 11 - AI Mode, Direction Indication, Bearing To Off-Screen
6.2.5 AI Mode – Baro Corrected Altitude Indicator
Baro corrected altitude can be configured for display on the right side
of the screen and shows the baro altitude in feet. When this field is
configured for altitude display, the lower right field will be locked to
the baro setting and cannot be modified to display a different
parameter.
Figure 12 - AI Mode, Altitude Indicator
The baro setting is adjusted utilizing the rotary knob. See Section
7.1- Push-Set Window for addition details.

UAV-1004233-001, AV-30-E Pilot’s Guide 20 Revision A
Baro setting in InHg or MB units can be configured during
installation but is not a pilot accessible setting.
On initial startup, the field will be dashed while sensor
stabilization occurs.
On unit power-down, the current field elevation and
barometric pressure are stored in internal non-volatile
memory. On the next power-up, this field elevation is
utilized to reverse compute and estimated baro setting,
potentially reducing the required adjustment amount
required by the pilot. During this reverse computation
process, the baro value will be shown in light grey.
