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.
