General Information
1.1 INTRODUCTION
This section contains a functional description of the 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 for the SKY899 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 a
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. If the SKY899 is connected to a WX-1000 processor and a WX-1000/SKY497 display, an
alternate display can not be connected to the soft-key inputs. Having both displays connected to
the soft-key inputs could result in conflicting input commands to the SKY899 and the WX-1000
processor.
3. For a list of compatible alternate displays refer to Service Memo 114. For additional assistance
contact Field Service Engineering at 1-800-453-0288 or 1-616-949-6600.
4. The SKY899 does not track intruder aircraft approaching at a closure rate greater than 1200 knots.
5. When interfacing to a weather radar indicator via the Radar Graphics Computer Model RGC250
with Enhanced Interface or RGC350. The RGC must be installed in accordance with the
installation manual supplied with each unit.
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 F).
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.
9. Software version 1.8 (or higher) and Mod D adds Verbal Intruder Positioning (ViP™),
SKYWATCH HP’s new extended audio callout feature. The ViP™ extended audio adds range,
relative altitude and relative bearing callout to the aural TA’s.
