GENERAL INFORMATION
1.1 INTRODUCTION
This section contains a functional description of the BFGoodrich Avionics Systems SKY899 traffic
alert/advisory system sensor, describes the various hardware and software configurations, outlines the
main features of the system, and provides a system block diagram. The SKY899 is a new generation traffic
alert/advisory system that has different inputs and outputs and it requires different wiring than the
SKY497. Connector P1 is keyed differently to prevent connection to the wrong TRC.
NOTES
1. The SKY899 is designed to be installed as a TCAS I traffic alert system or as a TAS
traffic advisory system. The system installation differences are as follows:
• TCAS I installations requires an alternate display device (i.e., EFIS, MFD, IVSI, weather
radar indicator) FAA approved for displaying TCAS I information and the antenna must be
an NY156 directional antenna.
• TAS installations can have an alternate display device, the WX-1000/SKY497 display, or
both as the primary means displaying traffic information. Either the NY156 or NY164
directional antenna can be used.
2. Contact Field Service Engineering at 1-800-453-0288 or 1-616-949-6600 for
approved displays and software version requirements of the TRC899.
3. The SKY899 does not track intruder aircraft approaching at a closure rate greater
than 1200 knots.
4. This section provides installation information for the SKY899 using the WX-
1000/SKY497 Display. If using an alternate display device refer to manufacturer
instructions for installation details.
5. When interfacing to a weather radar indicator via the BFGoodrich Avionics Systems
RGC250 (Radar Graphics Computer) refer to the RGC250 Installation Manual for
installation instructions. RGC250 must have software version 1.5 or later.
6. When an alternate display device is installed the service menu can not be accessed
via the display, therefore a terminal device (i.e., laptop) is required for system setup
and post-installation checkout (refer to appendix E).
7. When planning ARINC-429 receiver interfaces note that:
• The equipment connected to receive channels 1 and 2 must be the same speed
(12.5 or 100 kHz).
• The equipment connected to receive channels 3 and 4 must be the same speed
(12.5 or 100 kHz).
• Channel 5 receiver is independent of the other receivers and can be set to 12.5 or 100 kHz.
8. In order to use ADS-B SKYWATCH HP requires a GPS input that is GAMA or ARINC-743A
compliant.
