SkyTrax Operations 1-3
1 System Overview
This manual assumes that the pilot is appropriately licensed, is
proficient in operation of the aircraft and its equipment, and is in
compliance with all Federal Aviation Regulations (FARs).
All images contained in this manual are for reference use only,
and are subject to change.
Boxed areas marked as NOTE within this manual identify certain
situations or areas of operation having heightened safety
implications. While it is important for the operator to be familiar
with all of the information in the manual, it is essential to the safe
use of the SkyTrax that pilots give careful attention to the material
contained within these NOTEs.
The Avidyne SkyTrax system consists of a remote-mounted
receiver and one external antenna. The SkyTrax provides ADS-B,
ADS-R and TIS-B traffic information. SkyTrax models equipped
with a UAT receiver are also capable of receiving FIS-B weather
data. The SkyTrax does not provide ADS-B out functionality.
The SkyTrax may also be connected to the ARINC-429 traffic
output from a TAS or TCAS I system. When connected, the
SkyTrax will merge the TAS/TCAS traffic with the ADS-B traffic so
that only the best source of data for each target is displayed.
Interfaces will be to existing compatible displays such as Avidyne
Corporation’s FlightMax EX600/EX500 Multifunction Display
(MFD), Avidyne IFD4XX / IFD5XX Nav/Com/GPS/displays, and
Avidyne Release 9 Integrated Cockpit system. Other compatible
displays and display interfaces are described in the SkyTrax
Installation Manual 600-00335-000. Operation of the displays
including control of data products provided by the SkyTrax
receiver will be described in the operating instructions for those
separately approved displays.
This installation is intended for aircraft listed in an Approved
Model List, Avidyne document AVMLB-003.
Note that the AML for this STC is restricted to Part 23 Class I
and Class II airplanes (aircraft under 6000 lbs).

EQUIPMENT DESCRIPTION
This SkyTrax receives ADS-B messages from other UAT and/or
1090ES equipped aircraft and receives TIS-B/ADS-R/FIS-B
messages from ADS-B Ground Stations. Data received by the
SkyTrax Receiver is output to a compatible display device.
SkyTrax Receiver
The SkyTrax performs the following functions:
•ADS-B In (978MHz and/or 1090MHz)
oReceives ADS-B from target aircraft
oReceives ADS-R and TIS-B from ground stations
•Receives FIS-B Weather (if equipped with 978MHz)
•Receives traffic from a connected TAS or TCAS-I
•Merges all traffic sources into a single combined view
•Outputs ADS-B Traffic over an ARINC-429 port
•Outputs ADS-B Traffic over an RS-232 port
•Outputs ADS-B Weather over an RS-232 port
