1.2 Overview
This manual applies to the Avidyne SkyTrax 1xx and SkyTrax 2xx series of products,
which will be collectively referred to as simply SkyTrax in the remainder of this
manual. Where a specific model is being referenced, the full model name will be used.
The SkyTrax system consists of a remote-mounted receiver and one external antenna.
ADS-B, ADS-R and TIS-B traffic information is provided by all SkyTrax models.
SkyTrax models with a UAT receiver are capable of receiving FIS-B weather data. The
SkyTrax does not provide ADS-B out functionality.
The SkyTrax 1xx series of products provide ADS-B In capability for a single frequency
(either 978MHz UAT or 1090MHz). The SkyTrax 2xx series of products provides dual-
frequency ADS-B In capability.
All interfaces will be to aircraft equipment installed via separate installation approvals ;
Avidyne Corporation’s FlightMax EX600/EX500 Multifunction Display (MFD),
Avidyne IFD4XX / IFD5XX Nav/Com/GPS/displays, Aspen EFD1000 displays, and
Avidyne Release 9 Integrated Cockpit system. Function of other displays that may be
compatible based on interface type must be validated by the installer.
This installation is intended for aircraft listed in STC SA00401BO Approved Model List,
Avidyne document AVMLB-003.
Note that the AML for STC SA00401BOis restricted to Part 23 Class I and Class II
(aircraft under 6000 lbs.) airplanes.

2. Installation Considerations
2.1 Installation
This manual stipulates the requirements for an airworthy installation under STC
SA00401BO.
The Antenna must be installed no less than 2 feet from any L-Band (Transponder,
TCAS, TAS, DME) antenna. Failure to adhere to this critical installation note will result
in failure of the SkyTrax Receiver.
The STC does not support antenna installations on pressure vessels or composite
aircraft without additional approved data. If additional approved data is required,
contact Avidyne for guidance.
The STC has been evaluated to support FAR23 Class I and II aircraft in accordance with
the current Approved Model List.
Installation of the SkyTrax in other aircraft classes will require alternate means of
approval; i.e. STC, Field Approval.
2.2 Accessories and Packing List
2.2.1 Unpacking Equipment
Carefully unpack the equipment from the shipping container. Inspect the SkyTrax
Receiver unit and the package contents for evidence of shipping damage. Retain the
shipping container and packaging material for reshipment if necessary.
2.2.2 Package Contents
The items included in the SkyTrax package are listed in Tables 2-1and 2-2.

3. Equipment Description
This unit receives messages from other ADS-B Out equipped aircraft and receives TIS-B
and ADS-R messages from ADS-B Ground Stations. Models equipped with a UAT
receiver will also receive FIS-B weather data from ADS-B Ground Stations. Data
received by the SkyTrax Receiver is output to a display device.

3.3 System Configurations
The SkyTrax Receiver may be configured with a GPS position source (required for
traffic reception, but not required for FIS-B weather reception). The SkyTrax Receiver
may also be configured with an indicator (e.g. IFD4XX, IFD5XX) to display ADS-B,
ADS-R, TIS-B traffic and FIS-B weather. Figure 3-2 depicts the typical SkyTrax
Receiver system configuration.
Figure 3-2: SkyTrax Receiver with External Compliant GPS

Avidyne SkyTrax Series ADS-B Receiver Installation Manual
600-00335-000, Rev: 02 © Copyright 2021 Avidyne Corporation Page 15
3.3.1 GPS Position Source
If traffic is to be displayed, then the SkyTrax must be configured with a GPS position
source input. The GPS position source may be obtained externally via RS-232 (using
ADS-B+ G or ADS-B+ G2 format) or ARINC-743. GPS position input sources to the
SkyTrax other than from equipment identified in this manual must be verified by the
installer.
3.3.2 Display
The SkyTrax outputs traffic and weather information to compatible displays. Traffic
information can be provided using the Capstone protocol over an RS-232 interface (refer
to section 3.7.3.2), or the ARINC-735B TCAS protocol over an ARINC-429 interface
(refer to section 3.7.4). SkyTrax systems with UAT capability can also provide weather
information using the Capstone protocol over an RS-232 interface. The SkyTrax
Capstone output can be configured to provide traffic-only, weather-only or both traffic
and weather. A display with multiple available communications interfaces can take
advantage of the traffic-only and weather-only interfaces by dedicating the full
bandwidth of one interface to traffic and the full bandwidth of a second interface to
weather. The ability to display traffic and/or weather depends on the display device
and software version. The following displays support the display of traffic and/or
weather:

3.3.3 Maintenance Port
The SkyTrax provides a communication port that is used to configure and monitor the
status of the SkyTrax system via a computer. The maintenance port is required to be
used to configure the ICAO Address, NACv Value, and to manually configure the
RS232 com Tx ports if required. The SkyTrax should automatically “Discover” the
RS232 Rx inputs. The maintenance port is located on the front of the SkyTrax and is a
USB type C jack.
3.3.4 SkyTrax Configuration
The SkyTrax uses the internal Command Interface for configuration and
troubleshooting. The Command Interface can be accessed using a computer running
terminal emulation software by connecting it to the SkyTrax USB Maintenance Port. A
USB type A to USB type C cable will typically be required to connect the computer to
the SkyTrax.
3.4 Antenna Requirements
3.4.1 Antenna
The SkyTrax requires one antenna meeting the following specification: standard 50Ω
vertically polarized L band antenna rated for 978MHz and 1090MHz. Table 3-4 contains
a list of antennas that are recommended for use with the SkyTrax.
3.5 Installation
This section describes the installation of the SkyTrax Receiver and Antenna including
mounting, wiring, and connections. A post installation checkout procedure is included
at the end of this section.
3.5.1 Pre-Installation Information
Read this entire section before proceeding with the installation of the SkyTrax.
Perform the post installation checkout described in Section 3.8 prior to closing the work
area to resolve wiring, mounting and configuration issues should they occur.
Follow avionics installation practices per FAA Advisory Circular (AC) 43.13-1B, 43-13-
2A, or FAA approved revisions to these documents.
Perform an electrical load analysis on the aircraft prior to installation to ensure that the
aircraft’s electrical system is capable of carrying the SkyTrax load. Section 3.6.2
describes the power consumption of the SkyTrax.
3.5.2 Installation Overview
Installation of the SkyTrax Receiver and antenna requires determination of the location
of the Receiver, circuit breaker, antenna, and cable/wire routing to interfacing
equipment.
Installation of the identified compatible traffic/weather display is not covered in this
manual and should be installed in a manner approved by the FAA.

3.5.3 Tools Required
The D-Sub connector supplied with the SkyTrax uses crimp contacts.
Table 3-5: Acceptable crimp tooling
3.5.4 SkyTrax Receiver Mounting
Select a mounting location on a sufficiently flat surface that has the ability to withstand
the inertial forces imposed by the 1.3 pound receiver unit plus 0.5 pounds of cables. The
CG of the unit is shown in the following figures. Reference AC 43.13-2B chapters 1 and
2 for installation and support structure requirements and guidance. Modification of
primary aircraft structure will require separate approval. When locating the SkyTrax,
allow for four inches of clearance on the connector side of the unit to provide room for
wiring.
Mount the SkyTrax Receiver with 4 each AN3()A bolts, 4 each MS21083-N3 nuts and 8
each washers where the washers are placed on both the bolt and nut side. Nutplates
such as MS21059-3 or MS21076-3 may be used in lieu of the nuts, installed using
MS20426AD3 rivets. Bolt hole size should be 0.195 to 0.229 inches diameter. Refer to
Figure 3-3 for the SkyTrax mounting hole pattern.
